1.3 Ink Stains
1.3.1 Ink path
Be careful not to touch the ink path as it may stain your hands, clothes, printer, work
table etc., during servicing.
The ink path consists of the BJ cartridge nozzles, head cap, waste ink tube, head
wiper, cleaner unit, maintenance jet receiving section, and waste ink absorber.
CAUTION
Although the ink and ink optimizer for plain paper are not harmful to the human body, they contain organic solvents indicated on the package. Avoid getting the ink into your mouth and eyes, and store out of reach of children. If ink does get into your eyes, wash with plenty of water and consult a doctor. If for some reason a large amount of ink is swallowed, consult a doctor immediately. Give the doctor the information on the BJ cartridge package. This ink contains dyes, that cannot be removed from clothing, etc.

The joints and ink outlets of the respective ink tanks of the photo BJ cartridge [BC­62e Photo] and color BJ cartridge [BC-61] are also part of the ink path and must be handled with care. Unless absolutely necessary, do not remove the ink tanks from a BJ cartridge, since air may enter the ink path and have a negative effect on print quality.
The BJC-7100 uses a variety of inks and an ink optimizer for printing on plain paper. The ink optimizer is an almost colorless, transparent fluid. We will refer to the ink optimizer for plain paper simply as ink optimizer or just optimizer for simplicity purposes. We will also refer to the various colored inks and the ink optimizer for plain paper simply as "inks".
1.3.2 Ink mist
The BJ cartridge ejects ink onto the paper. After prolonged or heavy-duty use of the printer, a small amount of ink mist splattered during printing can dirty the printer such as the platen. Turn off the power, open the front cover, and clean the dirty parts with a soft moist cloth. This is to prevent dirtying the paper, your hands, and clothing from touching these parts.

1.4 Live Parts
When the plug of the printer's AC adapter is plugged into a live power outlet, the power supply unit of the printer is live regardless of the power being set to ON or OFF using the
POWER
button. Be careful not to get on electric shock if you are checking the printer operation with the covers off.
CAUTION
Do not attempt to dismantle the AC adapter. The mains AC voltage is supplied to the primary side of the AC adapter. To prevent risk of electric shock, do not attempt to dismantle the AC adapter to check its operation, etc.
If faulty, the AC adapter must be replaced as one unit (service part). The structural components, including the case, are not available individually as service parts. Do not attempt to dismantle the AC adapter.

Part 1: Safety and Precautions
Figure 1-6 AC Adapter
1.5 BJ Cartridge Metal Plate
Do not touch the BJ cartridge's metal plate as it may be very hot. The metal plate heats up during printing and becomes particularly hot during heavy duty printing.
CAUTION
Danger! High Temperature! Do not touch.
The printer has the following protective mechanisms to detect overheating:
1. Overheat detection when replacing cartridge
If overheating is detected, a beeper sounds four times and the carriage does not return to the replacement position. This is to prevent the user from touching the BJ cartridge's metal plate. Resume the cartridge replacement after leaving the cartridge to cool for several minutes.
2. Overheat detection during normal printing
The carriage movement and the paper eject operation are continued while the printing is stopped. Depending on the outcome of the ink-out detection after completion of printing a page, a beeper sounds to indicate the status of the error.
Ink available: BJ cartridge overheat error (beeper sounds 7 times)
Ink out: Ink-out error (beeper sounds 3 or 4 times) When a BJ cartridge overheat error occurs, leave the cartridge to cool for several minutes then press the
RESUME
button. These protective mechanisms are based on the temperatures detected by the sensors in the BJ head.
If the protective mechanism is activated and normal operation cannot be resumed after cooling the head for several minutes, see
"Part 5: 6.
TROUBLESHOOTING" (page 5-13)
.
For details of ink-out detection, see
"Part 4: 5.2.3 Ink-out detection" (page 4-48)

2. MACHINE PRECAUTIONS

2.1 BJ Cartridge Handling
2.1.1 Unpacking the BJ cartridge
Do not unpack the BJ cartridge until you are ready to use it. Before installing the BJ cartridge in the printer, remove the cap protecting the nozzles and gently peel off the protective tape. Do not attempt to reuse the cap or the tape after they have been removed, as doing so may cause faulty printing.
If you replace the cap on the color BJ cartridge or photo BJ cartridge, the sponge in the cap may cause the colors to bleed into each other. The nozzles may also become clogged.
Always move the carriage to the BJ cartridge replacement position before attempting to remove or install a cartridge. Failure to do so may result in damage to the BJ cartridge.
2.1.2 BJ cartridge protection
To prevent the nozzles from clogging, never touch or wipe the nozzles, joint pipes, or ink tank outlets with your bare hands or with tissue paper, etc. After removing the cap and peeling off the protective tape from a BJ cartridge, promptly install the cartridge in the printer or store it in the cartridge holder. If the BJ cartridge is not capped or stored in the cartridge holder, the nozzles may clog due to dried out ink or dust, etc. Do not attempt to leave color BJ cartridges or photo BJ cartridges with their ink tanks removed. BJ cartridges cannot be disassembled, reassembled, or washed.
Clogged nozzles cause faulty printing. If this problem persists even after the nozzles are cleaned, replace the BJ cartridge.

2.1.3 Power on/off
When the printer is turned off with the
POWER
button, the printer automatically caps the BJ cartridge's nozzles for protection and to prevent ink leakage. If the AC adapter is unplugged before the printer is turned off with the
POWER
button, the nozzles may not be capped. In this case, plug the AC adapter again, start up the printer and turn off the printer with the
POWER
button before unplugging the power cord. Note that, if you unplug the power during the recovery operation and then leave the printer, the purge unit may be damaged.
If the nozzles are not capped, the ink might dry out and clog the nozzles or leak from the cartridge.
2.1.4 When not using the printer
Keep the BC-60 BJ cartridge installed in the printer even when the printer is not in use. The BC-62e Photo and BC-61 BJ cartridges can be left installed in the printer or stored in the cartridge holder. This also applies when carrying, transporting, or storing the printer.
If the BJ cartridge is taken out of the printer, dried ink or dust may clog the nozzles, resulting in inconsistent printing. If the printer is moved or transported with no cartridge installed, ink may leak from the cap mechanism.

2.1.5 Ink electroconductivity
The ink used in the BJ cartridge can conduct electricity. If any ink leaks into the printer's mechanical parts, use paper towels, etc., to wipe clean. If the ink leaks onto the printer's electrical components, use tissue paper, etc., to wipe clean. If the ink gets to the IC chips on the PCB, or if it is too difficult to thoroughly clean off the ink, replace the respective parts.
Never connect the printer's power cord if ink has leaked inside the printer. It may damage the circuitry.
2.2 Ink Tank Handling
2.2.1 Unpacking the ink tank
Do not unpack the ink tank until you are ready to use it. Before installing it in the color BJ cartridge, remove the cap covering the ink outlets.
2.2.2 Preventing clogging
To prevent poor ink suction due to clogging of the joints in the BJ cartridge, never touch the ink tank's ink outlets. After removing the cap from the ink tank, promptly install the ink tank in the BJ cartridge to prevent the nozzles from clogging due to dried-out ink, dust, etc. Do not remove an ink tank from a BJ cartridge unless you are replacing it.

2.3 Printer Handling
2.3.1 Spurs
Take care not to bend the tips of the spurs. The spurs that transport and eject the paper after printing are very small and can easily be deformed. If a spur is deformed, its contacting surface with the printed paper increases, creating a dotted line.
2.3.2 Damage due to static electricity
The static charge accumulated by your body from clothing can damage electrical components and alter their electrical characteristics. Never touch the carriage contacts or BJ cartridge contacts.

2.3.3 Ink leakage and dry-out
Make sure a BJ cartridge is installed before turning off the power, using the
POWER
button. When you turn off the printer using the
POWER
button, the printer automatically
performs the following operations:
Cleaning
Any ink left in the purge unit or in the nozzles of the BJ cartridge is removed.
Capping
To prevent ink dry-out, the BJ cartridge's nozzles are capped automatically and the
carriage is locked in position. If you unplug the AC adapter by mistake, plug the power cord again, turn the power on and then off again using the
POWER
button, then unplug the AC adapter. If you turn the power off or unplug the AC adapter when the BJ cartridge has been removed, the nozzles will not be automatically capped or the carriage locked in position, and hence there is a risk of ink leaking or dry-out.
If the power cannot be turned on due to some failure, manually move the carriage belt or the carriage itself to the capping position. For details, see
"Part 3: 2.2 Manual Capping" (page 3-13).
2.3.4 Carrying the printer
Hold both sides of the bottom of the printer to carry it. Note that inserting your hand into the paper outlet may dislodge or damage the paper guides.

3. NOTES ON SERVICING

3.1 EEPROM Data
The printer stores the function settings and keeps track of various information including the total sheets printed, the number of cartridge replacements, the total waste ink amount, and the head position adjustment values. The data is stored in the EEPROM on the logic board. Note the following precautions during servicing:
1) Before servicing
You can check the EEPROM data with a test print. The total sheets printed can give you an idea of how much the printer has been used.
2) During logic board replacement
Always replace the waste ink absorber when replacing the EEPROM. If you do not replace the waste ink absorber, the data on waste ink amount will differ from the amount of ink that can be absorbed by the waste ink absorber. There is therefore a risk of ink leaking. When replacing the logic board, be sure to reset all the data. Because the data on new EEPROMs is undefined, they cannot be used until they are reset. For details of handling EEPROMs, see
"Part 3: 3.4 EEPROM" (page 3-19)
.
3) After waste ink absorber replacement
After replacing full waste ink absorbers, reset the EEPROM's waste ink counter.
4) If you accidentally reset the EEPROM's waste ink amount data or all data
Once reset, the EEPROM data cannot be restored. If you accidentally reset the EEPROM, you must take the same steps as when replacing the logic board.
After the EEPROM is reset, the data it contained cannot be printed out with a test print. If you want to check the stored data, be sure to make a test print before resetting the EEPROM. Note that you cannot reenter the data from the printer's control panel or by using a computer. If the EEPROM is faulty, or all data is reset, all data is lost. Whenever possible, restore all data such as the head alignment to the user's settings.
During operation, the waste ink amount (EEPROM data) is automatically updated. An error message is displayed and operation halted when the waste ink absorber is nearly full. If this occurs, refer to
"Part 5: 6.
TROUBLESHOOTING" (page 5-13)
.
See
"Part 3: 3.8.3 Printing EEPROM data" (page 3-23)
for how to make a test print of the stored data. You can choose to either reset the waste ink counter or all data. See
"Part
3: 3.8.2 Resetting EEPROM data" (page 3-22)
for details.

3.2 Service Mode of Printer Driver
There are certain printer driver control functions, described below, that are, in principle, hidden from the end user. These service mode functions, which must be used with caution, are provided for service purposes only. See
"Part 3: 3.3.2 Service mode of printer driver" (page 3-18)
for details.
3.3 Protecting the Power Supply
The power supply for the BJC-7100 printer consists of an AC adapter and a power supply circuit on the logic board. Provided the AC supply is connected, the printer power supply is live whether or not the power is set ON or OFF using the
POWER
button. Always unplug the AC adapter from the power outlet before connecting it to or disconnecting it from the printer. Ignoring this warning can result in damage and failure of the printer power supply.
When moving the carriage by hand when, for example, manually capping the ink nozzles or releasing the carriage lock, do so slowly while paying attention to the operation of the carriage motor; the back electromotive force generated by moving the carriage horizontally may damage the motor control board. If it is necessary to move the carriage horizontally fairly frequently, such as when replacing or adjusting the carriage, temporarily disconnect the carriage motor connector from the control board.

3.4 Static Electricity
The electrostatic charge accumulated in clothing can damage electrical components and alter their electrical characteristics. Before disassembling the printer to service it, use a wriststrap or other grounded metal object to discharge the static electricity. The following parts must not be touched before you have discharged the static electricity from your body:
• Logic board, carriage board
• Motor control board
• Cable connectors and contacts
• BJ cartridge signal contacts

3.5 Disassembly and Assembly
3.5.1 Parts that cannot be disassembled
Do not disassemble the ribbon cable to the head on the carriage unit. The position in relation to the contacts with the BJ cartridge is factory adjusted, and cannot be readjusted during printer servicing. In addition, do not attempt to disassemble the AC adapter, BJ cartridge, or ink tanks. In principle, do not loosen any of the screws painted red in the printer mechanism (except when adjusting the head gap using the jig). The red screws hold the adjustable plate that determines the gap between the nozzles of the BJ cartridge and the platen. This gap is adjusted to the optimal value when the printer leaves the factory.
In addition to the above, do not attempt to disassemble any parts not shown disassembled in the exploded diagrams in the parts catalog. Failure to observe this warning may result in those parts not functioning as originally intended after they are reassembled.
3.5.2 Parts requiring careful attention during disassembly and assembly
The printer has many parts that can be damaged during disassembly and assembly. For details, see
"Part 5: 4. DISASSEMBLY AND REASSEMBLY" (page 5-4)
. Please read this section carefully before attempting to disassemble and assemble the printer. The printer also has many plastic parts. When disassembling the printer, take care not to break or bend the plastic hooks.
Some plastic parts contain glass fibers for extra rigidity and precision, but since their viscosity is low, the plastic hooks can break easily when excessive force is used. Do not pull a plastic hook with excessive force while unhooking it.
3.6 Self-Diagnosis
The printer has a self-diagnosis feature to detect hardware defects. The results of the self-diagnosis are indicated on the LED on the control panel, and by the beeper. For details, see
"Part 3: 3.1 Error Indications" (page 3-14).

1. PRODUCT OUTLINE

1.1 Outline
The BJC-7100 is a personal desktop color bubble-jet printer that uses a new 600dpi BJ cartridge and technology to achieve outstanding print quality and photographic realism. The printing process uses an ink optimizer to enable water resistance printing on plain paper. The BJC-7100 printer uses new accurate photo BJ cartridge BC-62e Photo and new paper eject mechanisum to achieve high speed printing with high quality print. The BJC-7100 printer, which is easy to operate under Microsoft Windows, and is compatible with the Internet and multimedia tools such as digital cameras, is targeted at a wide range of users in the small-office and personal-computer environments who require high-quality full color printing.
The ink optimizer is an almost colorless, transparent fluid. For simplicity in this manual, we refer to the ink optimizer for plain paper simply as ink optimizer or just optimizer. We also refer to the various colored inks and the ink optimizer for plain paper simply as "inks".

1.2 Features
1. The new 600dpi BJ cartridge provides high-resolution printing at up to 1200 (H) ×
600 (V) dpi when using the exclusive printer driver. There are three types of new BJ cartridge: BC-60, BC-62e Photo, and BC-61. (Note that the BJ cartridge configuration differs according to the country.)
2. The printer is equipped with two BJ cartridges. The BC-60 is normally installed in the printer and either the BC-62e Photo or BC-61 is installed as required for the type of printing to be carried out.
3. The print process uses an ink optimizer to enable maximum water resistance when printing on plain paper (and envelopes). In this new printing process, the surface of the paper is coated with the ink optimizer prior to being printed. The ink optimizer is discharged from the special BJ head of the BC-60.
4. The straight manual insertion path allows printing on a wide variety of papers. In addition, the automatic platen-head adjustment mechanism obviates the need for levers for selecting papers and platen-head gap.
5. The printer performs high speed print; HQ: 5.8ppm, HS: 7.6ppm (BK; PC magazine)
6. The printer is equipped with an ink-out detection function based on the conduction of static electricity. An electrical signal is input to the ink path in the BJ cartridge. This signal is picked up by the electrode on the carriage, and the signal level is used to determine the existence or absence of ink.
7. The printer is equipped with an IEEE1284-compatible bidirectional parallel interface. This interface is compatible with nibble mode and ECP mode.
8. The built-in control mode is the Canon extended mode. The host computer sends print signals in Canon extended mode, generated by the special printer driver.
9. The printer is supplied with Windows 3.1, Windows 95 and Windows 98 special printer driver.
10. The printer is powered by an AC adaptor, installed by manufucturing.
The ink optimizer printing process can be used in both monochrome and color printing when the printer driver is set to plain paper (including postcards and envelopes) in all but Draft mode. It cannot be used if the driver is set to other than plain paper (special papers and film, etc.).
The ink-out detection mechanism confirms that the BJ cartridge is out of ink. The mechanism does not measure the amount of ink remaining in the cartridge and therefore does not necessarily indicate an error at the point where print quality deteriorates as the ink runs out.

1.3 BJ Cartridge
1.3.1 Black BJ cartridge (BC-60)
The BC-60 BJ cartridge is used for monochrome printing and for printing using the ink optimizer. It is a head and ink tank integrated type, disposable BJ cartridge consisting of a unified BJ head and ink tanks for black ink and ink optimizer. There are two parallel BJ heads, each with 304 nozzles. One head supplies ink while the other supplies the ink optimizer. Replace the BJ cartridge if either the black ink or ink optimizer runs out, or if satisfactory printing cannot be achieved even after the stipulated cleaning operations have been performed. Also replace the cartridge if more than 12 months has elapsed after the seal is broken. The BC-60 BJ cartridge will print approximately 870 pages of a standard 1500­character print pattern (Default setting of Text mode).

1.3.2 Photo BJ cartridge (BC-62e Photo)
The BJ head for the BC-62e Photo has been modified to considerably improve the ink jet emission precision. The BC-62e Photo BJ cartridge is used for photo-realism (super photo mode) (when printing photographs with substantial numbers of half-tones and light colors). The cartridge consists of a main unit that separates the BJ heads, and disposable ink tanks (BCI-62 photo). There are two parallel BJ heads, each with 240 nozzles. One head supplies color inks while the other supplies photo inks. Both BJ heads have three vertical rows of 80 nozzles each for yellow, magenta, and cyan. The total 6 ink tanks for color and photo inks are integrated. The BC-62e Photo BJ cartridge works by layering the photo inks, which are about 1/3rd the density of the color inks, thereby enabling pale colors and halftones to be printed. The color inks are used to print denser colors and fill larger areas with one color. Replace the ink tanks if any of the 6 inks runs out, or if satisfactory printing cannot be achieved even after the stipulated cleaning operations have been performed. If you still cannot obtain satisfactory print quality, replace the BJ cartridge. Also replace the cartridge if more than 12 months has elapsed after the seal is broken. (Replace the ink tank 6 months after the seal is broken.) The BC-62e Photo BJ cartridge will print approximately 90 pages per tank of a standard photo print pattern (Reference data).

1.3.3 Color BJ cartridge (BC-61)
The BC-61 BJ cartridge is used for color printing (denser colors and filling larger areas with color). The cartridge consists of a main unit that separates the BJ heads, and disposable ink tanks (BCI-61 Color). The BJ head has 240 nozzles supplying the color inks. There are three vertical rows of 80 nozzles each for yellow, magenta, and cyan. The 3 ink tanks are integrated. Replace the ink tanks if any of the 3 inks runs out, or if satisfactory printing cannot be achieved even after the stipulated cleaning operations have been performed. If you still cannot obtain satisfactory print quality, replace the BJ cartridge. Also replace the cartridge if more than 12 months has elapsed after the seal is broken. (Replace the ink tank 6 months after the seal is broken.) The BC-61 BJ cartridge will print approximately 275 pages per tank of a standard color print pattern.
1.3.4 BJ cartridge vs print mode
The inks are used in different ways according to the selected print mode, as shown in the table below.
: Used ▲: Used only for plain paper, envelopes ✕: Not used
When you use the BC-62e Photo BJ cartridge to print in color using only the normal color inks and not the photo inks, the normal color inks will run out and the ink tanks will have to be replaced before the photo inks are used up.
The estimated print quantity for the BC-60 (approximately 870 pages in monochrome) is for printing only in monochrome and assumes that the ink optimizer is not used up by color printing. If the ink optimizer is used in color printing, the cartridge may not print as many pages and it may be necessary to replace the BC-60 even if you do not print in monochrome at all.

7) Description of input/output signals Compatible Mode
Data Strobe [Input]
This signal is used to read DATA1 to DATA8. The signal becomes valid after the BUSY signal goes Low and the printer outputs an ACKNLG signal. This signal is normally High. After it goes Low, the printer receives data. When the signal remains Low, the printer does not operate until it goes High.
Data1 to 8 [Input]
The printer receives data with the DATA STROBE signal. The state of each bit of the signal must be maintained for at least 0.5µs from the rising edge of the DATA STROBE signal.
Acknlg [Output]
This signal is a response signal to the DATA STROBE signal. The host computer does not send the next DATA STROBE signal until this signal is sent. When the power is turned on or the BUSY signal goes Low for the input of the INIT signal, this signal is sent regardless of the DATA STROBE signal.
Busy [Output]
When this signal is High, the printer is BUSY; when Low, the printer is READY. The printer receives data at least 1 Byte when Data Stobe signal is input in the case Busy signal goes to "H" regardless of receiving data. The signal is High in the following cases:
• When receiving data
• When input buffer is full
• When INIT signal is input
• When carriage is in cartridge replacement position
• During manual cleaning
• When an error occurs (paper-out, paper jam, etc.)
• During soft power on/off sequence
• During internal initialization
PE [Output]
This signal goes High when the printer cannot feed paper. The BUSY signal goes High and the SELECT and FAULT signals go Low. This signal goes Low when the reset key was pressed and paper is loaded and fed. The FAULT and SELECT signals then go from Low to High. If paper is not ejected (paper jam) after an eject operation, this signal and the BUSY signal go High, and the SELECT and FAULT signals go Low. In this case, the signals do not change even if the paper is removed manually.
Select [Output]
The printer is READY when this signal is High. This signal goes Low when an error occurs (paper-out, paper jam, etc.) or when the carriage is in the cartridge replacement position. Fault signal goes to low 50ms after Busy signal goes to high.
Auto Feed XT [Input]
This signal is only used for the transition from compatible mode to negotiation mode.
Part 2: Product Specifications
BJC-7100
2-14
Init [Input]
When it changes to Low, this signal sets the printer in the BUSY state, then resets the printer by changing from Low to High. The pules width of this signal is requiired longer than 5 micro seconds. On completion of initialization, the head retreats to the home position and the default print mode is selected.
Fault [Output]
This signal changes to Low when the printer detects an error and when the carriage is in the cartridge replacement position to inform the host computer of the error state.
Select in [Input]
This signal is only used for the transition from compatible mode to negotiation mode.
Nibble Mode
HostClk [Input]
This is the STROBE signal to read DATA 1 to DATA 8. When in negotiation phase this is the trigger signal to send the protocol confirmation to the printer. In nibble mode, this signal is always High so that the printer does not fetch data.
Data 1 to 8 [Input]
The data bus is not used in nibble mode.
Ptr Clk [Output]
The printer requests the host computer to read the data by making the Ptr Clk signal Low in the reverse data transmission phase. After finishing reading, the host computer notifies the printer of completion of data receiving by making the Host Busy AUTO FEED XT signal High.
Ptr Busy [Output]
This signal outputs the data to be sent to the host computer in the reverse data transmission phase. First, bit 3 of the transmission byte data is output, followed by bit 7.
Ack Data Req [Output]
This signal outputs the data to be sent to the host computer in the reverse data transmission phase. First, bit 2 of the transmission byte data is output, followed by bit 6. This signal is used as the trigger signal to inform the host computer of the printer’s condition in the negotiation phase.
This signal outputs the data to be sent to the host computer in the reverse data transmission phase. First, bit 1 of the transmission data is output, followed by bit
5. This signal informs the host computer whether the printer supports nibble mode in the negotiation phase. The printer supports nibble mode when this signal level changes to Low at the same time the Ack Data Req (PE) signal rises.
2-15
BJC-7100
Part 2: Product Specifications
Host Busy [Input]
Indicates that the host is ready to receive the data from the printer by making the Host Busy signal Low in the reverse data transmission phase. After that, it goes High when data is received from the printer to verify receiving data. This signal changes to High in response to the PtrClk (ACKING) signal changing to Low to change to the reverse data transmission phase.
Init
This signal is not used in nibble mode.
DataAvail [Output]
This signal outputs the data to be sent to the host computer in the reverse data transmission phase. First, bit 0 of the transmission data is output, followed by bit
4. Informs the host computer if there is reverse transmission data or not in the negotiation phase. If data is ready to be sent to the host computer, this signal changes to Low.
1284 Active (Input)
This signal confirms that the printer is an IEEE 1284-compatible device. This signal goes High at the start of the negotiation phase and remains High in nibble mode to indicate that the printer is operating in bidirectional mode. It changes to Low in the termination phase.
ECP mode
HostClk [Input]
This is the signal used in handshaking with PeriphAck (BUSY) signal when data is sent from the host computer to the printer. This signal changes to Low when data has been output to the data bus (Data1 to 8) This signal changes to High in response to the PeriphAck (BUSY) signal rising. It remains High in the reverse data transmission phase.
Data 1 to 8 [Input/Output]
These are input data signals when data is sent from the host computer to the printer. In the reverse data transmission phase, these are output signals, and the printer outputs data to the host computer using this data bus.
Periph Clk [Output]
This signal is always High when data is sent from the host computer to the printer. In the reverse data transmission phase, this signal changes to Low to indicate that data is output to the host computer. This signal changes to High in response to the HostAck (AUTO FEED XT) signal changing to High.
Periph Ack [Output]
When data is sent from the host computer to the printer, this signal changes to Low when the printer is ready to receive data. When the data has been received from the host computer, this signal changes to High. In the reverse data transmission phase, this signal indicates if the information output from the printer to the data bus is command information or data (Low: Command information; High: data).
Part 2: Product Specifications
BJC-7100
2-16
Ack Reverse [Output]
This signal remains High when data is sent from the host computer to the printer. It remains Low in the reverse data transmission phase. When switching from the forward to reverse data transmission phase, this signal changes to Low, to indicate that a request to switch modes has been received, in response to the fall of the Reverse Request (INIT) signal, which is sent by the host computer to request the switch. This signal changes to High, to indicate that the request to switch modes has been received, when the Reverse Request (INIT) signal rises.
This signal is always High in ECP mode.
Host Ack [Input]
When data is sent from the host computer to the printer, this signal indicates whether the signal information on the data bus is data or command information (Low: Command information; High: data). In reverse data transmission, this signal is used for handshaking with the Periph Clk (ACKNLG) signal. When the host is ready to receive data from the printer, this signal changes to Low, then changes to High when the data has been received.
Reverse Req [Input]
This signal changes to Low during the recovery phase (resending data) when data is sent from the host computer to the printer. This signal changes to High in response to the lowered Ack Reverse (PE) signal. This signal changes to Low on transition from the idle state in the forward data transmission phase to the reverse data transmission phase (when data is sent from the printer to the host computer). When Low, this signal indicates reverse data transmission. The signal changes to High on transition from reverse data transmission to forward data transmission.
Periph Req [Output]
This signal changes to Low when, during forward data transmission, the printer requests reverse data transmission. When the host computer changes from forward data transmission to reverse data transmission, this signal changes to High at the same time as the Ack Reverse (PE) signal in response to the fall in the Reverse Request (INIT) signal, which requests the switch in modes by the host computer.
1284 Active (Input)
This signal goes High at the start of the negotiation phase and remains High in ECP mode to indicate that the printer is operating in bidirectional mode. It changes to Low in the termination phase on exiting ECP mode.

1.3.3 Installing the BJ cartridge
1) Removing the BJ cartridge protectors
Remove the BJ cartridge from the package, then remove the cap and tape on the nozzles, as shown in the figure.
Do not reuse the cap and tape. It can clog the nozzles or mix the ink colors. Do not touch the nozzles when removing the tape as doing so may result in the head becoming scratched and dirt adhering to the head, resulting in poor printing. Do not shake the BJ cartridge after removing the cap and tape as doing so may result in ink spillage.
2) Installing the BJ cartridge
Open the printer’s front cover and install the BJ cartridge on the carriage. Install the BC-60 on the left holder and the BC-62e Photo (or BC-61) on the right holder. After installing the cartridge, press the

3) Aligning the print heads
Because two BJ cartridges are installed in the printer, differences in how they are secured and in the cartridges themselves can shift the way ink is ejected onto the paper. To even out any differences and ensure satisfactory print quality, follow the procedure below for adjusting the relative positions of the print heads after completing the setup procedure on the PC.
1) Load two or more sheets of standard A4-size plain paper into the sheet feeder.
2) Following the instructions on the Printer Driver's control sheet, print a Print Head Alignment Pattern.
3) Check the printed patterns to select the optimum A (vertical), B (horizontal), C (bidirectional 1) and D (bidirectional 2) alignment values.
4) Following the instructions on the Printer Driver's control sheet, print a High­Resolution Adjustment Pattern.
5) Check the printed pattern to select the optimum E (horizontal 1), F (bidirectional
1), G (horizontal 2) and H (bidirectional 2) adjustment.
6) Following the instructions on the Printer Driver's control sheet, quit the print head alignment procedure.
7) You can print the nozzle check pattern to check the print head alignment values after completing this procedure. To print the nozzle check pattern, refer to

1.3.4 Replacing the ink tanks
You can replace the ink tanks of the BC-61 and BC-62e Photo BJ cartridges (not the BC-60 BJ cartridge). Replace the ink tanks as described below.
1) When to replace the ink tank
Replace the ink tank in any of the following cases: the ink runs out, the ink tank is out of its package for over six months, and the printing quality does not improve even after the head is cleaned. The color ink tanks of the BC-61 and BC-62e Photo contain multiple colors; if one ink color runs out, the entire color ink tank must be replaced.
2) Removing an ink tank
Press the
REPLACE
button to move the carriage to the cartridge replacement position (you can also use the printer driver). As shown in Figure 3-8, lift the front of the ink tank to remove the ink tank from the holder. Do not touch or let your clothing come in contact with the ink feeds on the ink tank.
3) Installing an ink tank
Remove a new ink tank from its box, then remove the cap from the ink feeds as shown in Figure 3-9. Install the ink tank in the holder in the reverse procedure from that described above. After installing the ink tank in the holder, press the
REPLACE
button to return the
carriage to the capping position.

1.3.5 Cartridge container [SB-60]
The printer is supplied with a container for storing the BC-61 or BC-62e Photo BJ cartridges for users who are using both the BC-61 and BC-62e Photo. (Note that the BC-60 cannot be stored in the container.) When the BC-61 is installed in the printer, the BC-62e Photo is stored in the container, and vice versa. The container can be mounted on the back of the printer.
When storing the BC-61 or BC-62e Photo in the container, make sure the ink tanks are installed in the BJ cartridge holder. Make sure that the cartridge faces the correct way in the container. Do not shake or drop the container, as ink may spill.
The BJC-7100 use a range of inks and, when printing on plain paper, an ink optimizer for plain paper is used. The ink optimizer is an almost colorless, transparent fluid. For simplicity in this manual, we refer to the ink optimizer for plain paper simply as ink optimizer or just optimizer. We also refer to the various colored inks and the ink optimizer for plain paper simply as "inks".

1.4 Turning Printer Power On and Off
1.4.1 Turning the power on
When the printer is connected to a power supply, press the
POWER
button to turn it ON. The beeper sounds once and the printer initializes itself. If no BJ cartridge has been installed, the
POWER
indicator blinks to show that the printer is waiting for the cartridge to be installed. If a BJ cartridge has already been installed when the power is turned on, the
POWER
indicator lights to show that the printer is in standby mode. When the printer is first turned on after leaving the factory, it automatically performs a cleaning operation. This operation takes about 2 minutes during which the
POWER
indicator blinks to show that cleaning is being performed.
1.4.2 Turning the power off
If the printer is ON, press the
POWER
button to turn the printer OFF. When you turn the printer off, the printer automatically caps the BJ cartridge. During this sequence, the
POWER
indicator continues to blink. The
POWER
indicator turns off on completion of the power off sequence. Before unplugging the power cable from the wall outlet, make sure that the
POWER
indicator is off.
Do not unplug the power cable from the wall outlet before turning off the printer using the
POWER
button. If you unplug the power cable to disconnect the power, the BJ cartridge capping will not be performed and ink may leak and dry on the nozzles, deteriorating the print quality.
If you press the
POWER
button to turn off the power during a cleaning operation, the
POWER
indicator will continue to blink until the cleaning operation has been completed. The power turns off after the cleaning operation has been completed and the nozzles have been capped. Note that any errors occurring after the start of the power off sequence are ignored.

1.5 Loading Printer Paper
To obtain optimum print quality, either use the auto sheet feeder or the manual feed on the back of the printer, depending on the type of print paper you are using. Because this printer automatically adjusts the platen-head gap according to the paper being used, there are no paper selection or head gap levers. Note that the paper rest can also be extended to support larger paper sizes.

AC Adaptor and Power Cable
Once installed on the printer, the user does not need to remove the AC adaptor when disconnecting the power cord. Plug the power cable into a wall outlet.

2. TRANSPORTING THE PRINTER

When carrying or transporting the printer, keep the BJ cartridge installed in the printer or stored in the cartridge container. This prevents the ink from leaking and drying out in the nozzles. Also when both BC-61 and BC-62e Photo are in use, keep one cartridge installed in the printer and the other in the container.
2.1 Transporting the Printer
When transporting the printer, follow the procedure below:
1) Press the
POWER
button to turn off the printer.
2) Disconnect the interface cable.
3) Unplug the AC adaptor power cable from the wall outlet.
4) Open the front cover and check that the carriage is locked in the capping position (right side of printer). If a fault has occurred and the carriage is not in the capping position, move it manually to the capping position. (See below: Operations performed only by service personnel) If a fault has occurred and the user has moved the printer without the carriage being locked in the capping position, tape the carriage to the opposite side (left side) of the printer as an emergency measure.
5) Close the front cover
6) Pack the printer in its original packing materials. Be sure to use cushioning materials.

3. PRINTER SERVICING FUNCTIONS

3.1 Error Indications
The indicators in combination with the beeper indicate the nature of any error. There are two types of errors: operator call errors, which can be corrected by the user, and service call errors, which cannot be corrected by the user. The indicators show which type of error has occurred. If an operator call error occurs, the indicators light; if a service call error occurs, the indicators repeatedly blink a specific number of times, depending on symptoms.
3.1.1 Operator call errors
The error is displayed on the computer screen via the printer driver, and you can check the status of the error as shown in the table below by the number of times that the beeper on the main unit sounds. If the error is not corrected by the apparent means, as indicated by the error display, the fault may be elsewhere. In this case, refer to
"Part 5: 6. TROUBLESHOOTING" (page 5-13)
.
*1: A waste ink error (service call) will occur if you continue to use the printer.
When using a bidirectional parallel interface (Nibble or ECP Modes), a description of the error is displayed on the host computer’s screen.

TABLE 3-3 SERVICE CALLS
3.2 Warning Indications
The printer warns the operator of less serious error states by printing out messages and sounding the beeper. Printing is not forcibly stopped while warnings are displayed.
BJ cartridge mismatch warning
If you select the photo ink system using the printer driver controls and start printing with a color BJ cartridge [BC-61] installed, the printer functions as described below. If you select the standard color ink system using the printer driver controls and start printing with a photo BJ cartridge [BC-62e Photo] installed, it is possible to print, but a message is displayed indicating that it would be preferable to replace the BC-62e Photo cartridge with the BC-61 cartridge.
1) Windows 95/98
After the printer has received the print data, it displays a warning message on the host computer’s screen. Printing does not start. Replace the BC-61 with the BC-62 Photo, then start the print operation.
2) Windows 3.1
Only the data that can be printed with the color BJ cartridge is printed. By checking the printed page, the operator can see that there has been a BJ cartridge mismatch. Replace the BC-61 with the BC-62e Photo, then start the print operation.
BJ cartridge overheat warning (cartridge replacement-inhibited temperature)
This warning message is displayed when you press the
REPLACE
button or you select BJ cartridge or ink tank replacement via the printer driver’s controls but the head temperature sensor has registered a temperature greater than that prescribed for the head. When this warning is displayed, the printer beeper sounds 4 times and cartridge replacement is halted. The printer resumes operating when the head temperature has dropped to the prescribed value, or the head has been left for a minimum of 60 seconds without further heating.

3.3 Function Settings
This printer has no function selector for setting functions. Use the Windows driver to make the respective settings. For details, see the Windows Driver Guide included with the printer.
3.3.1 Items set by control function
Procedure
1) Open the printer driver control dialog box.
2) Select "Custom Setting" to open the custom setting dialog box.
3) Change the parameter of the appropriate setting. (The item is ON when a check mark appears in the checkbox.)
Settings
a) ECP mode
This setting selects whether or not to be used ECP mode when printing. "OFF": No ECP mode (default) "ON": ECP mode
b) High speed printing
This setting specifies whether or not to print at high speed by reducing the response of the printer. "OFF": Normal speed printing "ON": High speed printing (default)
c) Pause page
This setting specifies whether or not to use the function to prevents ink transfer between sheets by specifying a fixed waiting time after printing each page. "OFF": No pause after printing each page (default) "ON": Pause after printing each page

Figure 3-18 Windows 95 Driver Control Sheet (Sample)
3.3.2 Service mode of printer driver
There are certain printer driver control functions as service mode. These service mode functions, which must be used with caution, are provided for service purposes only. Procedure
1) Open the printer driver control dialog box.
2) Select "Custom Setting" while pressing down the shift key to open the custom setting dialog box. The dialog box contains the normal and service mode control settings.
3) Change the parameter of the appropriate setting. (The item is ON when a check mark appears in the checkbox.)
Settings
a) Pause scan
This setting specifies whether the carriage pauses between scans (the horizontal travel of the carriage) during printing. It takes ink longer to dry on transparencies and other special papers than on plain paper, and there is therefore a risk under certain ambient conditions of a drop in print quality. If the pause is set ON under such circumstances, the ink has a chance to dry between scans. However, printing takes much longer.
b) Economy cleaning (skip first power-on cleaning)
This setting determines if cleaning is performed when the power is first turned on after the power is connected.
"OFF": First power-on cleaning performed (default)
"ON": First power-on cleaning not performed If the AC power supply is frequently disconnected (such as when the printer is linked to a computer’s power supply), setting economy cleaning ON reduces ink consumption and minimizes the startup time by omitting the first power-on cleaning. When economy cleaning is set ON, the power-on cleaning using the 72­hour timer is also omitted, and there is a serious risk of a drop in print quality if the printer is left unused for a relatively long time.
c) Ink-out detection
This setting determines if the ink out detection function is on or off.
"ON": Ink out detection function on (default)
"OFF": Ink out detection function off Make sure the ink out detection function is on unless dealing with a user who does not want this function or you are checking for malfunctions in the detection system.

3.4 EEPROM
The EEPROM stores data such as the total page count, BJ cartridge installation/removal count, total waste ink amount, and customsettings. The page count and waste ink amount indicate the frequency with which the printer is used. The EEPROM must be reset when the logic board, EEPROM, or waste ink absorbers are replaced. See
"Part 5: 4.3 Waste Ink Absorbers" (page 5-6)
for details of replacing the waste
ink absorbers.
3.5 Cleaning the BJ Cartridge
If the printed page shows faults such as white lines or fragmentation, print a nozzle check pattern to see if the print head nozzles are clogged. If they are, operate cleaning function for the BJ cartridge to clear the nozzles, as described below. In addition to cleaning the print heads using online operations via the printer driver, the BJC-7100 also allows you to manually clean the heads using the
RESUME
button. Note, however, that if you perform manual cleaning, the heads of both BJ cartridges installed in the printer are cleaned. (You can clean just one of the heads if you use the printer driver.)
Manual Print Head Cleaning
1) With the printer power ON, press the
RESUME
button until the beeper sounds
once.
2) The
POWER
indicator blinks. (Any paper in the printer is ejected.)
3) Both BJ cartridges installed in the printer are cleaned.
4) On completion of cleaning, the beeper sounds and the
POWER
indicator lights
continuously.
Deep Cleaning
If after performing normal cleaning, the print quality is still not satisfactory, perform deep cleaning. Deep cleaning uses more ink than normal cleaning.
1) With the printer power ON, press the
RESUME
button until the beeper sounds
twice.
2) The
POWER
indicator blinks. (Any paper in the printer is ejected.)
3) Both BJ cartridges installed in the printer are deep cleaned.
4) On completion of deep cleaning, the beeper sounds and the
POWER
indicator lights
continuously.
The printer also automatically performs cleaning operations at the following times:
1) The first time the power is turned on with the
POWER
button after the AC power is
connected when the heads are not capped;
2) When a BJ cartridge or ink tank is replaced;
3) When an ink-out error is detected (ink-out detection cleaning ink-out detection display)
4) The first time the power is turned on with the
POWER
button after 72 hours or
more has elapsed since the last cleaning or deep cleaning operation;
5) When the dot count exceeds the prescribed value during printing.

3.6 Test Printout
This printer has a built-in self-test function that can be executed without any connection to a computer. With the power off, press and hold the
POWER
button until the beeper has sounded
twice. Release the
POWER
button to start the test print. If you print the nozzle check pattern on plain paper, you will not be able to check the printing of the ink optimizer, which is semi-transparent. In this case, check the checker pattern at the top right of the nozzle check pattern for ink smears to see the general status of ink optimizer jetting. If you need to check each nozzle for ink optimizer, print the nozzle check pattern on transparency material for bubble jet printers. Check the reflected light from the pattern to check the status of the nozzles. If it is difficult to see, coat the back surface with black ink, etc., or position the transparency on black paper. If you print a nozzle check pattern with the BC-61 cartridge installed, the part printed by the photo head shown in Figure 3-20 will not be printed.
3.7 Pickup Roller Cleaning Function (HR-101)

1.3 Print Signal Sequence
The following describes the sequence of signals from the time the host PC sends the print signals to the printer up to the point at which printing is performed. a) The host PC sends print signals to the printer.
The print signals consist of print data and control commands.
b) The printer controller receives the print signals and temporarily stores them in the
DRAM receive buffer.
c) The MPU fetches the print signals from the receive buffer and separates the print
data from the control commands based on the program in the control ROM.
The MPU processes the control commands based on the program in the control ROM. d) The MPU expands the print data in the DRAM print buffer. e) The printer controller receives the request to start printing from the MPU and the
print data is sent from the DRAM by DMA to the printer controller. f) The printer controller converts the print data into serial data for the respective BJ
heads and outputs this data to the BJ heads with control signals. The drive circuits in the BJ heads convert the serial data to parallel format and control the output of inks onto the print paper as indicated by the control signals.
g) The MPU and printer controller sense the status of the BJ heads and printer and
control the printer as a whole, including the motor drivers, etc.
The BJC-7100 supports the Canon extended (native) mode, but not emulation. The print signals sent from the host PC are therefore Canon extended mode signals converted by the printer driver.

1.4 BJ Cartridge Drive
The BJ cartridges are driven according to the print data and control signals output by the logic board. The control signals determine the timing with which ink is ejected from the nozzles in the BJ heads and the amount of ink. These are optimized by the printer controller according to the conditions shown bellow. The control signals also stabilize the amount of ink by keeping the BJ heads at the optimum temperature. The drive frequency is changed to 14.4kHz, 10.56kHz or 9.6kHz by print modes.

1.4.1 Print drive control
In the BJC-7100, printing is achieved by block dispersal drive, in which the three vertical rows of nozzles fire sequentially and driven alternately odd/even to minimize the concurrent firing of neighbouring nozzles. The heat enable signal consists of a pre-pulse and main pulse. To keep the ink jetting in the optimum state, the pulse width is varied according to the internal state of the printer, such as the head rank, printer temperature, and head temperature.
The BJC-7100 uses a range of inks and, when printing on plain paper or envelopes in other than draft mode, an ink optimizer for plain paper. The ink optimizer is an almost colorless, transparent fluid. For simplicity in this manual, we refer to the ink optimizer for plain paper simply as ink optimizer or just optimizer. We also refer to the various colored inks and the ink optimizer for plain paper simply as "inks".

2. FIRMWARE

2.1 Interface
The printer is equipped with an IEEE1284-compatible bidirectional parallel interface. This interface supports compatible mode, nibble mode, and ECP mode.
2.1.1 Compatible mode
In compatible mode, the parallel interface sends data in 8-bit units. Data is sent using handshaking based on the DATA STROBE, BUSY, and ACKNLG signals. When data (Data 1 to 8) and the DATA STROBE signal are input from the host PC, the printer controller, which controls the parallel interface, outputs a BUSY signal and latches the data signals as DATA STROBE falls. After the BUSY signal has been output, the printer controller fetches the latched data via the DRAM bus to the receive buffer in the DRAM. After writing the data to the receive buffer in the DRAM, the printer controller outputs an ACKNLG signal, sets the BUSY signal "Low", and waits to receive the next data from the host PC. The BJC-7100 can reduce the response time by the operation in the printer driver. This achieves faster printing, however, this may not work with some host computers.

2.1.2 Nibble mode
In nibble mode, 8-bit data is sent from the printer to the host PC in two 4-bit blocks.
The printer lowers the DataAvail signal when it is ready to send data to the host PC. After confirming the fall in the HostBusy signal, the printer prepares 8 bits of data and outputs the low 4 bits on the control signal line on the fall in the PtrClk signal. When the PtrClk signal drops, the host PC fetches the data and raises the HostBusy and PtrClk signals. Next, when the printer has confirmed the second drop in the HostBusy signal, it outputs the high 4 bits of data to the control signal line. If, after the HostBusy signal has risen, there is no more data to be sent to the host PC, the DataAvail signal rises and the printer enters a standby state until there is more data to be sent.
2.1.3 ECP mode
Because data is sent and received in both directions on the data bus in ECP mode, data can be received at high speed. Because control signals can be used to separate data from commands, and bidirectional communication can be established within this mode, there is no need to switch to other modes when switching the direction in which data is being sent. The data bus switches direction from forward to reverse data transmission in response to a fall in the AckReverse (PE) signal from the printer. The data bus switches direction from reverse to forward data transmission in response to a rise in the ReverseRequest (Init) signal.

2.2 Print Modes
The printer selects the carriage operation and bubblejet drive method on the basis of the media and print quality selected by the driver, and the print data that is received from the host PC. This enables the printer to achieve optimum print quality, free of smears and fragmentation. To improve the quality of images, the printer is designed to print the data using multiple passes of the carriage. By increasing the number of passes for the data as a whole, the time required for the ink for each piece of data to dry is split up, making ink smears less likely. The printer selects the optimum print mode according to the type of BJ cartridge(s) installed, the ink system being used, and the various settings, such as print media and print quality, selected using the printer driver.

2.2.1 Plain paper optimized printing mode (P-POP)
Only when you select plain paper (in other than draft mode) using the printer driver, the BJC-7100 ejects ink optimizer from the BC-60's ink optimizer head. The printer jets the ink optimizer onto the plain paper, followed by the normal ink to minimize smearing and improve the ink's water resistance.
2.2.2 Economy print mode (Draft mode)
Economy print mode is the fastest print mode of the BJC-7100. Printing is performed in single passes in bidirectional mode. Because of the speed and bidirectional passes, no ink optimizer is used in this mode, which also cannot be selected when using the photo ink system. Because less ink is used in this mode, the printed image is lighter.
2.2.3 Standard mode
The standard mode is further divided into two modes, "speed priority mode" and "quality priority mode." The speed priority mode is suitable for printing text and simple illustrations, whereas the quality priority mode is suitable for printing originals that contain mainly images. In the speed priority mode, the carriage makes a single pass per line at all times. This mode is basically unidirectional printing. When only black is being printed, the printing speed is improved by detecting parts of the original to be printed that do not contain print data on each horizontal line, and printing in both directions taking those lines as the threshold between unidirectional and bi-directional printing. In the quality priority mode, the carriage makes three passes per line to print at higher quality. In this mode, the printing speed decreases, and photo ink cannot be used.
2.2.4 High quality and fine mode
Photo print mode uses the thinner inks of the Photo BJ cartridge (BC-62e Photo) to suppress granularity when printing images with multiple halftones and high contrast. By combining color and photo inks to achieve nine halftones, not only is the BJC­7100 able to print high-contrast images, but also the subtle differences in intermediate tones. The photo inks are used in the low-density portions to minimize granularity. 600 × 1200 dpi (8pass) printing process achieves high quality printing without the photo inks.

2.3 Smoothing Function
The BJC-7100 has two methods of smoothing black print data. The printer driver can convert 600 × 600dpi data into data equivalent to 1200dpi (h) × 600dpi (v). The printer itself can also convert 300 × 300dpi data into data equivalent to 600 × 600dpi.
2.4 Print Optimization Controls
2.4.1 Power monitor
When, due to high-duty printing, etc., the total head drive power exceeds the power supply capacity, the consumption is automatically reduced.
2.4.2 Head sticking prevention
To prevent ink mist dispersion caused by high-duty printing, a one pass-worth of data is splitted and printed as a 2 pass data.
2.4.3 Ink smear prevention
Printed pages ejected from the printer dry naturally in the paper output tray. If, before a page has dried, the next printed page is ejected onto it, there is a risk that the ink on the first page will be smeared. When printing high-density images, etc., the BJC-7100 pauses the carriage between printing scans and/or delays the ejection of the printed page, to prevent smearing.

2.5 Head Overheat Protection
If the temperature of the print heads of the BJ cartridges is allowed to rise beyond a set temperature, not only is there a risk of burns in the event that the heads are touched, but it becomes increasingly difficult to achieve optimum print quality. The printer is therefore equipped with an overheat protection function that uses thermal sensors in the heads to prevent the temperature rising above the set temperature. Print head temperature detection is effected by independent sensors in the black head, optimizer head, color head, and photo head.
Protection level 1:
This protection level prevents the operator from touching the metal plate of a hot print head when changing the BJ cartridge. If, when replacing a head, the head temperature is higher than the temperature at which replacement is prevented, the printer displays a BJ cartridge overheat warning (and the beeper sounds 4 times). While the protection function is operating, the printer temporarily will not allow BJ cartridge or ink tank replacement.
Protection level 2:
The carriage returns to the home position after printing each line and waits for a maximum of 3 seconds to allow the print head to cool. This overheat protection mechanism continues for a minimum of 20 seconds.
Protection level 3:
If the head temperature continues to rise, the printer stops printing; the carriage continues to move and the paper is fed through the printer. The printer then discards any further data sent from the host PC, and performs cleaning operations, ink-out detection, and checks for failure of the head temperature sensor. If the printer determines that the ink or ink optimizer has run out, it displays an ink-out error when data is next received from the host PC. If the head temperature sensor is found to be faulty, the printer displays a BJ cartridge overheat error.
If the BJ cartridge head temperature sensor is faulty, the above overheat protection controls may not function correctly. If it detects a fault in the head temperature sensor, the BJC-7100 printer displays other hardware error messages (the head temperature sensor error message may not be displayed correctly). If the printer cannot recover from the overheat protection control operations to normal printing, or if other hardware error messages are displayed, replace the BJ cartridge. For details of how to recover from the respective error states, see

3.1.1 Structure of printer's mechanical system
1) BJ Cartridge/Ink Tank
The printer is shipped with the BC-60 BJ cartridge, which contains black ink and ink optimizer, and the BC-62e Photo BJ cartridge, which contains three color inks and three photo inks. The BC-61 color BJ cartridge which contains three color inks may be shipped instead of the BC-62e Photo. The BC-60 has a unified print head and ink tank, while the BC-62e Photo has separate head and ink tanks that can be replaced. The user can decide whether to use the combination of BC-60 and BC-62e Photo or BC-60 and BC-61 according to the type of data being printed.
2) Purge Unit
To ensure high-quality printing, the purge unit, which is driven by the paper feed motor, caps and wipes the face of the BJ cartridge print head to make sure that the ink can be ejected cleanly from the nozzles when printing. Functionally, the purge unit consists of a pump and wiper. The pump draws ink from the BJ cartridge and removes the ink from inside the cap. The wiper wipes the face of the head. When not printing, the nozzles of the BJ cartridge are capped to protect them.
3) Carriage
The carriage travels horizontally across the print paper driven via the carriage belt by the carriage motor. Print signals output by the logic board are sent via the carriage ribbon cable to the two BJ cartridges mounted on the carriage. The wiping hook on the bottom of the carriage trips the latch lever and wiper lever so that the ink optimizer head is wiped. By controlling the position of the slide lock lever of the purge unit, the carriage switches between paper feed/sheet feed drive and purge unit drive.
4) Paper Feed/Sheet Feeder
The built-in sheet feeder is driven by the paper feed motor and transports the print paper to the paper feeder. The paper feed, which is driven by the paper feed motor, rotates the feed rollers so that the print paper is transported vertically.
5) Paper Output
The paper output unit prevents smearing and dirtying by ink by providing a time interval up to when the paper being printed is stacked on top of the already printed paper on the output tray. This unit feeds printed print paper to the output tray as each sheet is printed. Print paper is fed to the output tray by the power of the paper feed roller. This power is transferred via the paper feed roller gear to the paper output roller inside the paper output unit to rotate the paper output roller. Paper end guides are located at both ends of the paper passage path in the paper output unit. When the paper is being output, both ends of the print paper are lifted up to slightly warp the paper, and the leading edge of the print paper being printed is made to hang down so that it does not contact the already printed paper on the output tray.
6) Manual Feed Slot
Paper can be fed into the printer manually from the manual feed slot on the back. Paper fed manually into the printer takes precedence over any print paper already in the sheet feeder.

3) Description of parts BJ Print Head (black head, ink optimizer head, color head, and photo head)
The heater board and aluminum plate are connected to the flexible cable.
Flexible Cable
The signal contacts are connected to the heater board by printed pattern wiring. The contacts are in contact with the signal contacts on the carriage, and are used for the input and output of print signals and sensor signals between the printer and BJ print head (heater board).
Heater Board
The heater board has a built-in drive circuit, and is set against the ink room of the head holder and the nozzles. The electrode for the ink-out detector is located at the ink room. The heater is aligned with the rows of nozzles against the nozzles.
Aluminum Plate
The aluminum plate supports the heater board and flexible cable.
Head Holder
The head holder supports the BJ print head. The ink room stores the inks that are supplied to the nozzles. The ink-out detection pulse is applied from the heater board electrode. The nozzles are formed by aligning the ink ejection grooves with the heater array on the heater board.
Head Stopper
The head stopper attaches the BJ print head to the head holder.
The heater board uses semiconductor technology, in which the heaters and ICs, etc., of the drive circuit are mounted on a silicon plate. When the heater drive starts, the ink in the nozzles gets hot, causing the formation of many bubbles. These finally form one bubble which, as it heats up, forces the ink to be ejected from the nozzle. Even when the heater is stopped, the residual heat causes bubbles to continue to form and ink to be ejected from the nozzle tips. The nozzle is replenished with ink after the ink has been ejected.
