Though the Stylus PHOTO 2100/2200 is similar in basic structure of the mechanism to the Stylus PHOTO 2000P, it has the following features.

• For compatibility with CD-R label direct printing, the CD-R tray adaptor and exclusive sensor are loaded. (Only for Stylus PHOTO 2100)

• To feed board paper and roll paper, the exclusive paper feed guide is fitted.

• For compatibility with the CD-R tray and correction of ink transfer to the roller, the

newly designed paper eject unit is provided.

Used for carriage driving. Makes little noise during driving. The CR linear scale and CR encoder sensor are used to control the motor.

Power source to drive the Paper loading rollers a t the time of fixed-value paper loading or paper feed/eject operation. To grasp the paper feed pitch, the precision gear surface is fitted with the PF scale and the PF encoder sensor is used to control the motor.

Drives the pump and performs paper feed operation from the ASF. Because of a stepping motor, this motor does not require a scale, photo sensor and like to be fitted to grasp the driving conditions.

2.2.1 Carriage Mechanism

The Carriage mechanism consists of the Carriage motor (CR motor), Carriage guide shafts A (main shaft), B (sub shaft), Platen gap adjustment mechanism, Carriage lock mechanism, and others.

2.2.1.1 Carriage Motor (CR Motor)

Like the one of the conventional Stylus PHOTO 2000P, the Carriage mechanism of this product uses a DC motor as a drive source. The following indicates the Carriage driving DC motor specifications.

Table 2-2. CR Motor Specifi ca tions

Item Specifications

Type DC motor with brushes Drive voltage +42V +/- 5%(voltage applied to driver) Winding resistance 23.0Ω +/- 15% Inductance 24.0mH +/- 25% Drive method PWM, constant-current chopping Drive IC A3958

The CR motor of the conventional model uses a stepping motor, and the carriage unit position was controlled by open loop control. To stabilize the printing qual ity and ensure silent operation, however, this product adopts the DC motor and linear encoderbased closed loop control like the Stylus PHOTO 2000P to control the Carriage speed and position. Also, the conventional DAC control was changed to PWM control. Simultaneously, the basic signal (PTS signal) is generated to time ink discharge.

Driven by the CR motor, the Carriage unit moves within the printing area along the Carriage guide shaft of the printer mechanism during printing.

Figure 2-2. Carriage Mechanism

Using low-cost DC motors, this product grasps the variations of the torque constants, coil resistances and power supply board output voltages of the individual DC motors adequately to carry out heat generation control according to individual differences. The variations of the torque constant, coil resistance and power supply board output voltage of the motor are measured in a CR variation measurement sequence when the CR mechanical load is in the initial status (Max. 150g.cm) and saved into the EEPROM (AC<H>). According to the variations (individual differences) measured in this sequence, the voltage is corrected to make the drive current value constant (without an individual difference) according to the variations (individual differences) measured in this sequence. Further, to set the appropriate drive current value according to the variation of the CR mechanical load, the mechanical load is measured in a CR measurement sequence and saved into the EEPROM 6C<H>, 6D<H> in a power-on or IC change sequence. However, if 14 is saved at the EEPROM 6C<H> and 05 at 6D<H>, Fatal error will occur since too large load is applied to the CR drive system. Accordingly, not only the mechanical load but also the variations of the motor and like are taken into consideration to correct the drive current value of the CR motor. In addition, a heating value is calculated from the CR drive current value, and when the specified heating value is reached, wait time (0.3s to 7.9s) is provided per CR path for printing.

2.2.1.2 Carriage Home Position Detection

To detect the Carriage home position, the drive current of the CR motor and the speed/ position signal of the CR linear encoder are used as in the conventional Stylus PHOTO 2000P. The basic home position detection sequence is as descri bed below.

1. The CR linear encoder pulse counter in the CPU is reset by the initialization

operation performed at power-on.

2. When the CR motor rotates counterclockwise, the Carriage moves from left to

right. When the following conditions are satisfied, the CPU assumes that the Carriage made contact with the right frame.

2.1 When the ASIC detected 750/1500 counts or more in the PWM output under CR motor load positioning control, the temporary home position A is set as contact with the frame.

2.2 P1 (number of output pulses from when power is switched on until the Carriage makes contact with the right frame) is 40 steps or less between reset 0 and A.

3. When the CR motor rotates clockwise, the Carriage moves from right to left. When the following conditions are satisfied, the CPU assumes that the Carriage made contact with the CR lock lever.

3.1 When the ASIC detected 480/1500 counts or more in the PWM output under CR motor load positioning control, the printer judges that the Carriage made contact with the CR lock lever.

position. If a position difference between the temporary home position A and the second frame contact position B is 4 steps or less, the printer judges it as a home position.

Based on the output pulses (signals) from the CR linear encoder, the IC30 (ASIC) sets the drive current value adequate for the carriage motion (carriage moving direction and carriage position) of each operation and outputs it to the motor driver as a special control signal. Based on the signal output from the IC30 (ASIC), the IC24 (CR motor driver) outputs the CR motor drive current to the CR motor.

3.2 A difference between P2 (number of output pulses from when the Carriage made contact with the right frame until it makes contact with the Carriage lock lever) and P1 is yy or less, and the number of outputs between A and CR lock lever is 40 steps or less.

4. When the CR motor rotates counterclockwise to move the Carriage from left to right and the CPU detects 750/1500 counts or more in the PWM output under CR motor load positioning control, the printer judges it as contact with the frame. At this time, the carriage position B is stored.

5. If a difference between P3 (number of output pulses from when the Carriage made contact with the Carriage lock lever until it makes contact with the right frame) and P1 has become Z or less, the printer judges that the Carriage is in the home

2.2.1.3 Sequence Used for PW Detection

The PW detector on the Carriage unit bottom performs the following sequence.

! Off-paper printing prevention control

Before start of printing (immediately after the end of paper locating) or during printing, whether paper is present or not is detected to prevent off-paper printing onto the Paper guide. (Applied to only the left or right end of the paper) If the sent data has the paper size that is larger than the fed paper size, trimming is executed according to the paper size detected by the PW sensor, and frame printing is performed (frame width 2mm). Reversely, if the received data has the paper size that is smaller than the fed paper size, frame printing is also performed. This feature is designed to prevent off-paper printing onto the Paper guide by frameless printing performed in a wrong using method. However, in the fast mode for plain paper or postcards, paper width detection is not executed to improve the throughput. When the above using method is performed, the specifications of trimming and frame printing are not applied.

! CD-R center detection control (Only for Stylus PHOTO 2100)

When printing is not being performed, the PW detector is used to detect the center of CD-R.

Refer to 2.2.3.6 "CD-R Printing Mechanism (Only for Stylus PHOTO 2100)" for details.

! Board paper/roll paper leading edge detection control

Control exercised to detect the user-preset board paper leading edge, or control carried out to detect the roll paper edge. Therefore, the PW sensor does not detect a paper leading edge at the time of ASF cut sheet feeding.

! Off-range restriction control

At the time of frameless printing, a paper leading edge is detected using the PW detector to restrict the frameless off-range amount.

" Auto sheet feeder complete frameless mode

In the complete frameless mode, control is performed to print the print data 3mm larger at top, 5mm larger at bottom, and 2.5mm lager at left and right than the detected paper size. (3mm larger at top, 5mm larger at bottom, and 3.5mm lager at left and right for A3 or A3+ size)

" Roll paper mode

In the left and right frameless mode, control is performed to print the print data 2.5mm lager at left and right than the detected paper size. (3mm larger at top, 5mm larger at bottom, and 2.5mm lager at left and right when the fixed-format mode is selected)

! PW sensor dark voltage (VH) measurement

PW sensor dark voltage (VH) measurement is performed at the following timings and locations and used to calculate the threshold value of whethe r pap er is pr esent or not.

" Cut sheets, Roll paper

The dark voltage is measured and updated at every power-on, and the threshold value (VS) is calculated and saved in the EPROM 76<H> area as a PW detection level. The dark voltage is measured at 3poinst on the left flat portion of the the Paper Guide Front. If the PW level measured in the Papaer width measuerment sequence is less than the PW detection level stored in the EEPROM, it means the sensor is detecting the paper.

" CD-R tray (Only for Stylus PHOTO 2100)

When a CD-R is used, the dark voltage is measured on the CD-R tray, and the threshold valve (VS) is then calculated and saved in the EPROM 76<H> area as a PW detection level. If the PW sensor level measured in the CD-R HP detection sequence & CD-R center position detection sequence is less than the PW detection level stored in the EEPROM, it means the sensor is detecting the HP of the CD-R tray and the CD-R on the tray. Every paper or CD-R tray is loaded, the voltage measured on the Paper or CD-R tray is stored in the EEPROM BB<H> area as a white level.

OPERATING PRINCIPLES Printer Mechanism 43

Page 44

EPSON Stylus PHOTO 2100/2200 Revision B

However, the white level value is not used in the PW sensor-related firmware processing. The white level value is used to check the sensor deterioration condition during servicing or like. If the measurement value of the white level is close to that of the PW detection level, it means that the sensor is dirty or deteriorated.

2.2.2.3 Head Hot Error

If Head Hot occurred due to either of the following factors on the conventional printer, the Ink End value was written to the Ink consumption counter and Ink End error was displayed. This product displays Fatal error.

! Head Hot error factors

1. If more than half of all nozzles are clogged and cannot discharge ink, ink will not flow through the path, resulting in a Head Hot status.

2. If a multi-nozzle dropout attributable to a vertical fall or like occurs in more than half of all nozzles, ink will not flow through the path, resulting in a Head Hot status.

! Reason why Fatal error is displayed

If either of the above factors occurs, the conventional model that did not adopt the CSIC displayed Ink End error at occurrence of Head Hot. Reason: A wrong Ink End value was written to the Ink consumption counter by the ink cartridge removing/inserting operations performed before the Ink End error. Because of this, the Ink End error was adopted to prevent Head Hot that would be caused by continuous off-paper printing since the printer could not recognize an Ink End status if the Ink cartridge is in that status. On the model that adopts the CSIC, it is inconceivable that a wrong Ink End value is written to the Ink consumption counter, and Head Hot occurs only due to the above factors. However, when the nozzles are clogged, the chances that the user can restore it to normal are extremely remote, because if the user whose printer resulted in Head Hot installs a new Ink cartridge, the Ink End value is written to the Ink cartridge, and therefore, the printer will result in a Head Hot status again. As a result, the Ink cartridge has no problem but that Ink cartridge becomes unusable. To avoid this, the hardest CL is executed automatically to return from a multi-nozzle dropout in order to provide protection from the factor 2 at occurrence of the Head Hot error. If the Head Hot error still persists, Fatal error is displayed to prompt the user to send the printer to the repair center.

2.2.2.4 Pseudo Four-color Mode

This print mode can be selected in the detail setting mode when the plain paper is selected, and means the draft mode. In this mode, the printer operates as a pseudo four-color printer, with Lines A and B used for one color of BK, Lines C and D for one color of C, Lines E and F for one color of M, and Line G for one color of Y. Therefore, since two lines of head nozzles are used as one color for each of BK, C and M, 192 nozzles are used for each color and the printing resolution is 360 x 360dpi. For Y, the resolution is 360 x 180dpi and 96 nozzles are used. The JFK of the driver creates the four-color 360 x 360dpi mode and sends it to the printer. For Y, however, the dot structures of the top and bottom lines are ORed to print on one line.

2.2.3.2 Drive Transmission Path to ASF Unit

1. The Carriage unit moves to the right end of the Carriage guide shaft to move the DE lock lever to the right end.

2. The ASF/Pump motor rotates in the CCW direction (as viewed from the motor pinion gear side) by the specified number of steps.

3. As the ASF/Pump motor rotates in the CCW direction, the Planetary lever unit in the DE mechanism moves toward the combination gear 12, 22.4.

4. As the Carriage unit moves leftward from the right end of the Carriage guide shaft by the specified number of steps, the DE lock lever fixes the Planetary lever unit.

5. The driving force of the ASF/Pump motor is transmitted in the following path. Motor pinion gear → Planetary lever unit → Combination gear 12, 22.4 → Combination gear 14, 28 → Spur gear 32 (ASF side)

2.2.3.3 ASF Paper Feeding Operation

Using the driving force transmitted from the ASF/Pump motor via the DE mechanism, the ASF unit performs the following paper feeding operation. To achieve stable paper feeding operation of the paper feeding mechanism of this product, the double-feed prevention mechanism is installed in the ASF. To prevent paper from dropping into the paper path from the paper setting position in the ASF unit, the Paper return lever returns the paper to within the ASF hopper securely, and the LD roller then starts paper feeding operation. Refer to the following steps for details of the paper feeding operation including that of the double-feed prevention mechanism.

1. At power-on, the ASF/Pump motor rotates in the CCW direction and the ASF home position is detected. Then, the ASF/Pump motor rotates in the CW direction by the specified number of steps, thereby setting the LD roller and Paper return lever in the paper feeding standby position. Refer to [Standby status] in Figure 2-7, "Paper Feeding Operation".

2. When you give a paper feeding command from the PC and press the Paper switch on the panel, the ASF/Pump motor rotates in t he CCW direct ion an d th e LD rol ler starts paper feeding. Refer to [Paper feeding status] in Figure 2-7, "Paper Feeding Operation".

3. When the paper is transferred from the ASF unit to the PF roller and detected by the PE sensor, the LD roller stops in the position where the friction of the LD roller is cleared. Refer to [PF roller passing status] in Figure 2-7, "Paper Feeding Operation".

2.2.3.4 Manual Paper Feeding Mechanism (Board Paper)

To enable direct printing onto thick paper and CD-R label, this product has the mechanism to feed paper from the printer front and rear manually. Move the Release lever to the farthest position, insert thick paper from the rear manual feed slot until its leading edge reaches a position about 1cm from the PF/Driven roller, and set the Release lever in the thick paper mode. When the PE sensor detects the paper after the above Release lever has been operated, pressing the Paper feed switch causes the PW sensor to detect the leading edge of the paper and the printer to perform paper locating control and enter the standby status.

2.2.3.5 Roll Paper Feeding

Since panel operation in the roll paper mode differs from the above operation, the differences of panel operation after roll paper feeding will be described.

1. When roll paper is fed with the Release lever not in the release position, the PE sensor detects the paper, and after 2 seconds has elapsed, the paper is fed.

2. The PW sensor check for the leading edge of the paper, and if it detects the paper, the printer operates in the cutter self-cleaning mode.

3. The printer back-feeds the paper to the paper print starting position.

As explained above, when roll paper is inserted from the Roll paper feeding guide to the paper feeding position of the PE sensor, paper is automatically fed and back-fed to the print starting position. At this time, panel switch operation is invalid (since 02<H> is written to 3F<H> in the EEPROM), and the definitions of the panel operation and Paper feed switch differ between cut sheets and roll paper. When roll paper is fed, 02<H> is written to the EEPROM 3F<H> area, but when roll paper print data is received from the PC, 01<H> is written to the 3F<H> area. Panel switch operation differs as described below between when 02<H> is written to the 3F<H> area and when 01<H> is written there.

! When 02<H> is written

Pressing the Roll paper cut switch for more than 3 seconds back-feeds the leading edge of the roll paper to the PE sensor (the Paper LED blinks). When the roll paper is removed from under the PE sensor in this state, paper is fed from the ASF.

! When 01<H> is written and cutter is fitted

When the data from the photo quicker is "No auto cut", pressing the Roll paper cut switch after end of printing feeds the separation position in the print data to the roll paper cut position and returns the leading edge of the paper to the print starting position after paper cutting. When the data from the photo quicker is "Standard 1 cut" or "Specific 2 cuts", the roll paper is cut automatically at every separation of the print data, and the leading edge of the paper is then returned to the print starting position.

When 01<H> is written and cutter is not fitted Pressing the Roll paper cut switch after end of printing prints a tear-off line and

feeds the roll paper to the roll paper cut position. When you cut the roll paper with scissors or like and then press the Roll paper switch again, the paper returns to the print starting position.

The auto cut setting section of the print option in the photo quicker is displayed according to the Auto cutter fitting radio button setting in the printer information within the driver.

! CD-R tray home position detection sequence

When the CD-R attachment is fitted, the Release lever setting position (PG sensor: Close, Release sensor: Open) and CD-R tray sensor (Close) are detected. By pushing the CD-R tray into the specified position and pressing the Paper feed switch in this status, the following operation is performed.

1. The Carriage unit moves to the CD-R tray home position detection position (white label position).

2. The CD-R tray is pulled in the ASF direction.

3. When the PW sensor of the Carriage unit detects the CD-R home position, the Carriage unit moves to the CD-R tray center position (horizontal center of the CD).

4. The CD-R tray is fed in the paper ejection direction and the trailing edge of the CD-R is detected. Then, the CD-R tray is fed in the ASF direction again and the leading edge of the CD-R is detected. After that, the CD-R tray is fed to the CD-R tray center position in the paper ejection direction.

5. In the position in Step 4, the Carriage unit moves rightward and the detection of the CD-R horizontal direction starts. After the left end of the CD-R is detected, the Carriage unit moves rightward again and the CD-R horizontal direction is detected.

6. The Carriage unit stops at the CD-R tray home position detection position (paper feeding direction) and the CD-R tray is fed in the paper ejection direction. When the home position is detected, both the Carriage unit and CD-R tray stop operating and are put in a standby status.

If the CD-R tray home position or CD-R cannot be detected in the specified step operation of each step in the above sequence, the CD-R tray is ejected and Paper out error is displayed. If the Release lever setting position (PG sensor: Close, Release sensor: Open) and CD-R tray sensor (Close) are detected when the CD-R attachment is fitted, pressing the Paper feed switch will not start paper feed from the ASF. In this case, pressing the Paper feed switch performs the CD-R tray home position detection sequence.

When the CD-R tray is detected, Release lever error is displayed if the Release lever setting position is other than the CD-R position.

As compared to the Stylus PHOTO 2000P, the spring load of the Knurled rollers above the Paper eject roller (Paper guide front side) is about 1/4 lower to reduce the traces of the Knurled rollers. Therefore, the main purpose of installing these Knurled rollers is not paper transfer but its main function is to hold down transferred paper during printing. As compared to the Stylus PHOTO 2000P, the rubber roller on the paper eject side (Paper eject roller) has the following features to fully dry ink that may be transferred to the Paper eject roller.

• Roller diameter : About twice larger

• Position : Placed about three times longer distance away

! Wait time

Photo-ink (HCD ink: Photo-black, Light-black) is easy to dry, but Matte-ink (PPI ink: Matte-black) is difficult to dry. For the medium that uses Matte-black, therefore, paper is transferred after a maximum of 2 second wait time has elapsed after printing according to paper loading amount conditions.

" Waiting conditions

1. When the paper loading instruction is 2672/1440 steps or more, paper loading starts after the wait time.

2. When the paper loading amount is less than 2672/1440 steps, the time taken between paper loading and printing up to the roller is estimated so that the time to reach the roller will be the wait time.

2.2.5 Ink System Mechanism

The Ink system mechanism consists of the Pump unit (including the Carriage lock lever) and Capping mechanism. The Cap unit is in close contact with the CR unit and drains ink from the Ink cartridge to Head cavities to Cap to Waste ink pad using the driving force of the Pump unit.

2.2.5.1 Pump Mechanism

The Pump mechanism is designed to suck ink from the Printhead or Cap assembly. The Cap assembly has a built-in head cleaning wiper. The following gives the operation outline of the Pump mechanism. To provide the driving force of the Pump mechanism, a 4-phase, 48-pole PM type stepping motor is used as the ASF/Pump motor. For the specifications of the ASF/ Pump motor, refer to 2.2.3.1 Table 2-9 "ASF/Pump Motor Specifications". When the driving force of the ASF/Pump motor is switched to the Pump unit side by the DE mechanism, the functions of the Pump mechanism are as indicated in the following table depending on the rotation direction of the ASF/Pump motor.

The Capping mechanism uses the driving force of the Pump unit to come into close contact with the Head surface to suck ink from the Ink cartridges, Head and Cap, thereby securing air tightness in the Cap. When the printer is in a standby status or its power is OFF, the Capping mechanism is in close contact with the Head surface to secure moisture retention in the Cap, preventing the Head from being clogged with ink while the printer is stored.

2.2.6 Ink Sequence

The following ink sequence is executed according to various timer, counter, flag and other information saved on the EEPROM.

! CSIC-related sequence

The ink type 1 code stored in the CSIC memory chip is identical regardless of the Japanese domestic or overseas cartridges, and is saved at the main board EEPROM A0<H> - A7<H>. If data is read from each color CSIC and Ink cartridge error is not displayed at power-on, Ink end error is displayed. If the read data have no problems, the CSIC data status is made valid. After CSIC operation is checked, the ink consumption of the I/C currently installed per color is compared with the ink consumption saved in the printer EEPROM, and control is performed under the following conditions.

" When current I/C consumption differs (from ink consumption in EEPROM)

1. On the assumption that the I/C has been changed at power-off, the first I/C

flag is reset.

2. The installation count in the printer EEPROM is updated for the CSIC.

In the CSIC information replacement sequence, the CSIC side ink consumption data is updated to the ink consumption data in the printer EEPROM.

" When current I/C consumption is the same (as ink consumption in EEPROM)

1. When the initial filling flag is set and the CSIC side ink consumption is 0, the printer judges that initial filling is not yet performed. (The printer before initial filling judges that the I/C is fitted in a power-off status.)

2. Installation count updating, CSIC information replacement, and initial filling are executed in this order.

3. If the initial filling flag is not set, the printer judges that I/C change was not made at power-off and regards the CSIC data as valid.

Data is written to the CSIC at power-off, in the power saving mode, at the time of cartridge change, or at the time of cleaning.

1. Data is read from the CSIC and developed in the RAM on the main board.

2. The data is compared with the ink consumption in the printer EEPROM. If the data are the same, the data is written to th e CSIC. If they are different, only the consumed difference is added and written to the CSIC. When cleaning is performed, the CL count is also written, and when the I/C is changed, the installation count is also written.

3. The used model name data on the I/C side is rewritten.

Note: Reason why the used model name data is rewritten from the printer to the I/C:

To grasp which printer used the I/C removed.

4. After that, the change flag 2 (flag that indicates change CL) is set and CL is executed. If the ink set (Line A, Line B) of the current I/C differs from the ink set in the EEPROM, replacement CL3 is executed.

OPERATING PRINCIPLES Printer Mechanism 60

EPSON Stylus PHOTO 2100/2200 Revision B

Initial ink filling

! Replacement cleaning, change cleaning

When the printer is powered on for the first time after the purchase of the product, the printer executes the initial ink filling operation to fill the ink cavities of the Head with ink. When the initial ink filling operation is performed properly, the printer clears the flag in the EEPROM so that initial ink filling operation will not be performed when it is powered on next. The Stylus PHOTO 2100/2200 requires about 90 seconds to perform the initial ink filling operation and consumes about 1/ 7 of the new monochrome ink cartridge. If the sequence does not end normally during initial filling, the initial filling flag is not cleared and the CL operating flag is set. Because of these flags, when powered on next time, the printer assumes that it was powered off for some reason during initial filling and executes CL3 instead of the initial filling sequence. (On the conventional mode, initial filling was executed again. However, when this operation was performed, ink was wasted and therefore CL3 is executed to cover the ink filling performance.) When the initial filling flag is set and the CL operating flag is not set, the printer assumes that the initial filling was not executed at all (power was switched on but the cartridges were not set), and when the printer is powered on next time, it executes initial filling.

This product has three patterns of black ink combinations in Lines A and B. Refer to Table 2-3 "Relationships between Nozzle Lines and Color Arrangement" on page 44. When the Carriage is within the home position and the ink types of Lines A and B are changed within the above patterns during ink cartridge change, three different replacement CLs are executed depending on the ink types to prevent mixture of the old ink and new ink. If the ink types of Lines A and B are not changed, change CL is executed instead of replacement CL.

Timer cleaning

2.2.7 Paper Cutter Mechanism

This printer consumes the ink of up to 1.27g/color depending on the combination of the cumulative printing timer, cumulative cleaning count and cleaning timer.

! Flushing

This printer executes two different flushings for the following purposes.

" Periodic flushing

This is done to prevent ink viscosity in the Printhead nozzles from increasing during continuous printing. A specific small amount of ink is discharged into the Cap according to the Periodic flushing timer.

" Periodic large-amount flushing

This is done to prevent ink viscosity in the Printhead nozzles from increasing during continuous printing. A large amount of ink is discharged into the Cap according to the Periodic large-amount flushing timer.

The Paper cutter mechanism consists of such main parts as the Cutter motor, left and right HP sensors (2 pcs. in all), Relay board, Paper eject roller shaft and Paper holddown flap in the Cutter unit.

! Operation during printing

When the Cutter blade starts cutting, the Paper hold-down flap rises and holds the paper during cutting. The HP sensors for detection of the Cutter blade position are installed on both ends of the cutter operation area, detect whether the Cutter blade operates properly, and displays Cutter position error or Cutter jam error according to the operating condition.

2.2.7.1 Cutter Initialization Sequence

When the Cutter is fitted, the cutter initialization sequence is executed if the printer has confirmed that the Cutter has been fitted (the Power switch blinks about 5 seconds). The cutter initialization sequence is an operation performed to securely put the Cutter blade in a standby position detected by the right HP sensor if the Cutter blade is not detected by the right HP sensor. In the initialization sequence, if the Cutter blade does not reach the HP sensor (right or left) within 3 seconds in either rightward or leftward Cutter motion, Cutter position error occurs. If the Cutter blade is in the right HP sensor position when the Cutter is fitted, the initialization operation is not performed specifically.

In Cutter operation, Cutter position error or Cutter jam error is detected. Differences between these errors are as follows.

! Cutter jam error

If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is returned to the HP sensor located in the motion starting position (right HP sensor). At this time, Cutter jam error occurs if the Cutter blade can return to the HP sensor position located in the motion starting position within 3 seconds.

! Cutter position error

If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is returned to the HP sensor located in the motion starting position (right HP sensor). At this time, Cutter position error occurs if the Cutter blade cannot return to the HP sensor position located in the motion starting position within 3 seconds.

2.2.7.2 Cutter Self-cleaning

In the Cutter unit, there is a plate (plate where the paper print surface comes into contact) above the Paper hold-down flap. This sequence indicates the operation performed to hold down and remove the ink, which may stick to that plate, with the leading edge of the fed roll paper. Since the Cutter blade must be operated left-to-right to operate the Paper hold-down flap, the Cutter blade generates operating noise during cutter self-CL when the roll paper is fed.

2.2.7.3 Cutter Cleaning (Driver Side)

This sequence is executed on the driver side. By cutting the roll paper three times (T.B.D.) at intervals of 6cm, the ink that may stick to the Cutter blade is removed to clean the Cutter blade.

Paper cutting by the Cutter consists of the basic cutting sequences 1 and 2. The basic sequence 1 means movement from the right HP sensor to the left HP sensor. At this time, as soon as the Cutter blade starts moving from the right HP sensor, the timer starts. If the left HP sensor does not detect the Cutter blade within 3 seconds, the cutter initialization sequence is executed and then Cutter jam error or Cutter position error occurs. The basic cutting sequence 2 means movement from the left HP sensor to the right HP sensor. At this time, if the Cutter blade cannot move from the left HP sensor to the right HP sensor within 3 seconds, Cutter position error occurs.

2.2.8 Power-On Sequence

The following explains the operation to be performed when there is paper or no paper and the Carriage is inside or outside the HP with the printer powered on.

! Without paper/Carriage inside HP (CR locked)

1. When power is switched on, the drive of the CR motor is transmitted to the Carriage through the timing belt.

2. Using the transmitted drive, the Carriage starts operation in the following path to seek for the home position.

• Home position → Right frame → CR lock lever → Right frame →

Home position

3. The drive from the PF motor is transmitted to the Paper eject roller shaft A and the CR is unlocked.

• PF motor → Spur gear 76 → Combination gear 17, 24.5 → Spur gear 43 →

Paper eject roller shaft A → CR lock

4. In the path indicated in Sequence 1, after the Carriage has moved to the right frame (second time), the drive of the ASF/Pump motor is transmitted to the LD roller shaft through each gear of the DE unit to rotate the LD roller shaft, placing the ASF unit in the home position.

• ASF/Pump motor → Planetary lever unit → Combination gear 12, 22.4 →

Combination gear 14, 28 → Spur gear 32 (ASF side) → LD roller shaft

5. The unlocked Carriage moves to the left frame and then returns to the right frame. The Carriage stops there for about 5 seconds, and during that period, the PF roller shaft and Paper eject roller shafts A, B start rotating slowly.

• PF motor → Spur gear 76 (PF roller shaft) → Combination gear 17, 24.5 →

Spur gear 43 → Paper eject roller shaft A

• PF motor → Spur gear 76 (PF roller shaft) → Combination gear 17, 24.5 →

Spur gear 62 → Paper eject roller shaft B

6. The PF roller shaft and Paper eject roller shafts A, B stop rotating once, but restart rotating suddenly. When the Carriage moves between the left and right frames again, the ASF unit returns to the pre-power-on status (initial status), and the Carriage returns to the home position and is fixed by the CR lock lever.

! Without paper/Carriage outside HP

1. When power is switched on, the drive of the CR motor is transmitted to the Carriage through the timing belt.

2. Using the transmitted drive, the Carriage moves to the home position slowly.

3. When the Carriage reaches the home position, the PF roller shaft and Paper eject roller shafts A, B start running suddenly by the drive from the PF motor but stop soon, and the Carriage is fixed by the CR lock lever.

• PF motor → Spur gear 76 (PF roller shaft) → Combination gear 17, 24.5 →

Spur gear 43 → Paper eject roller shaft A

• PF motor → Spur gear 76 (PF roller shaft) → Combination gear 17, 24.5 →

Spur gear 62 → Paper eject roller shaft B

4. After that, the operation as in "Without paper/Carriage inside HP" is performed.

! With paper/Carriage inside HP (CR locked)

Operation is the same as in "Without paper/Carriage inside HP". When there is paper, however, the operation perf ormed when the ASF unit detects the home position will be explained here additionally. The following operat ion is the same as in "Without paper/Carriage inside HP" or "Without paper/Carriage outside HP", provided that there is no paper.

1. The Paper return lever installed on the LD roller unit goes down to feed the paper but stops above the Paper separation pad.

2. After that, when the ASF unit returns to the pre-power-on status (initial status), the Paper return lever moves back the paper that was stopping above the Paper separation pad. This is done to prevent double feed during paper feeding.

3. The Carriage is fixed by the CR lock lever.

! With paper/Carriage outside HP

In addition to the operation in "Without paper/Carriage outside HP", the motion of the Paper return lever in "With paper/Carriage inside HP" is performed.

2.3.1 Power Supply Circuit Operating Principle

The power supply circuit board of this product is the C387 PSB/PSE. The basic structure of the circuit uses the RCC switching regulator method and +42VDC and +5DVC are supplied to the printer mechanism and control boards.

The following indicates the applications of the voltages generated in this power supply circuit.

Voltage Applications

• CR motor +42 +/- 2VDC Rated output current: 0.5A

+5 +/- 0.25VDC Rated output current: 0.6A

Note: +5VDC applies to only the parts and areas in the above table. 3.3V/2.5V drive

components are used as most logic chips (CPU, P-ROM, SDRAM) on the C387MAIN board. Hence, they do not operate at the +5VDC regulator DC generated by the C387PSB/PSE. Each 3.3V/2.5V drive chip operates at 3.3V/2.5V reduced by the 3.3V/

2.5V generating regulator on the MAIN board circuit.

2.3.2 C387MAIN Circuit Operating Principle

The C387MAIN board consists of the logic circuits (CPU, ASIC, PROM, SDRAM, 1394 controller, USB2.0 controller), various motor control/drive circuits (CR motor, PF motor, ASF/Pump motor), head control/drive circuit, interfaces (1284, USB, 1394, USB2.0), sensor circuits, combination circuits (RTC, reset, EEPROM) and electrical double-layer capacitor. There are the following two great differences between the control circuits of this product and conventional model.

! Adoption of 3.3V/2.5V drive logic circuit components

The 3.3V/2.5V voltage is generated by the Regulator ICs (IC15, IC31) installed on the C387MAIN board that reduces +5VDC generated by the C387PSB/PSE board, and is used to drive multiple components. This is done to save power of the logic circuit.

The following table indicates the 3.3V/2.5V drive components and 5V drive components.
