1.2.6 Preventing Data Transfer Time-Outs

Generally, hosts abandon data transfer to peripherals when a peripheral is in the busy state for dozens of seconds continuously. To prevent hosts from entering this kind of time-out period, the printer slows down the data reception rate to about one byte per second when there is less than 4kb of free space in the printer buffer. Data reception comes to a complete stop if the free space is less than 32 bytes, but returns to one byte per second when free space reaches 1KB or more.
Product Description Interfaces 30
EPSON Stylus Pro 7000 Revision B

1.2.7 Interface Selection

The SP 7000 has one slot for an optional Type-B interface and two built-in interfaces; the USB and parallel interfaces.
The printer has only two internal BUS lines for the interfaces, so the parallel and USB interfaces share one line while the other line is exclusive to the Type-B interface. The USB interface takes priority when both interfaces are connected meaning the USB interface works but the parallel does not. Make sure nothing is connected to the USB interface before printing via the parallel interface.
Interface status and selection
When the option interface is selected, the parallel/USB interface goes into the busy state. The LH signal is “L” at this time. “L” means the power is cut, in other words 1284 does not respond. Therefore, the LH check is required via the Reverse channel. The USB interface responds NACK and cannot receive data.
The the option interface is not selected, an off-line bit is set to Main Status Register (MNSTS). When the printer initializes or returns to the idle state, the USB interface is out of the NACK condition and resets the off-line bit of the Main Status Register to option interface.
The parallel or USB interface can operate normally even if an optional Type-B interface is installed and connected. The interface in use can be selected automatically or manually.
Manual selection
The interface can be manually determined using the Printer Setting Menu; see SelecType in the user’s guide for details.
The choices are INTERFACE = PARA/USB or INTERFACE = OPTION.
Automatic selection
If the interface setting is set to “AUTO” (default), the printer scans the interfaces for incoming data. The interface that receives data first is selected.
As long as the host sends data or the printer interface is in the busy state, the interface selection does not change.
When the host stops transferring data and the printer is in the stand-by state for a certain period of time, the printer returns to the idle state.
Be aware that an interrupt signal such as the -INIT signal only takes effect on the parallel interface when the parallel interface is selected.
When the printer is initialized or returns to an idle state, the parallel interface enters a ready condition, the serial DTR signal is set to low, and the off-line bit of the Main Status Register (MNSTS) is reset.
The /INIT signal on the parallel interface is not active while that interface is in Nibble or ECP Mode, or is not selected.

CUTTER SPECIFICATIONS

Attributes: Consumable item that is replaced by the user, and it
is made of very hard steel, so the blade can be chipped. Handle carefully to avoid cuts to yourself and to avoid chipping the blade.
Life: The cutter can cut well over 2,000 sheets of paper,
but the actual wear-and-tear depends on the type and thickness of the paper used. The cutter life can be determined manually; attempt to cut a piece of normal paper and if the cutter easily cuts the paper, it is OK. Unlike the cutter position with the EPSON Stylus Pro 9000, the SP 7000 cutter position is automatically determined by the carriage cover position. No adjustment is needed for the cutter position or the carriage cover height.

T/B 15MM = the printed image is the same size whether the margin is 15mm or 3mm. The difference is 12mm of paper clearance is added to the top and bottom edges to make paper feeding more stable and to prevent the paper from rubbing the printheads.
If the print area is greater than the width of the printable area of the paper, the printer ignores the extra print data on the right side of the paper.
Paper size check
You can disable the paper size check to prevent “RELOAD PAPER” errors which may occur when using very thin paper or paper with low reflective qualities such as tracing paper.
The print area is determined manually, and the printheads will fire ink onto the platen if the print area is set larger than the actual paper size.

1.7 Maintenance Request

There are several consumable parts in the printer, and the printer employs separate counters to keep track of each one. The “Maintenance Req. 0100” message appears on the display to warn the user when the Waste Ink pads are about 99% full.
The printer can continue to print even though the “Maintenance Req. 0100* message appears instead of the “Ready” or “Printing” message. However, when the waste ink counter determines the Waste Ink pads are 100% full, the “Service Req 00000100” message appears and the printer can no longer print.
To clear this condition, perform the following.
Replace: The following items must be replaced.
- Waste Ink Pads
- Pump Assembly
- Cap Assembly
- FBox
- Cleaner, Head
The above mentioned items are available as a kit.

2.2 Description of Components

2.2.1 Carriage Movement

To print on paper as wide as A1+ (24 inches), the carriage must be quite stable and must travel further than the usual carriage. To increase stability, the SP 7000 uses a carriage guide rail instead of the carriage guide shaft. The carriage comes into direct contact with the printer frame using a set of bearings which are attached to the carriage.
The CR motor (DC motor) drives the carriage, and the Linear Encoder sensor in combination with the T-Fence (plastic timing fence found underneath the carriage guide rail) determine the lateral position of the carriage. As shown in Figure 2-7 below, the Linear Encoder reads the timing stripes to determine the position of the carriage as well as the carriage speed, and this data is sent to the software servo.
NOTE: CR motor errors (such as overcurrent) and encoder sensor
malfunctions can be caused by simple problems; for example dust/ink on the T-Fence or the T-Fence is out of the sensor.
The following sensors are used in combination with the carriage components:
Home Position Sensor This optical sensor activates when the CR Guide Rail flag enters the space between the light emitter and the light receiver. The flag is located on the carriage and the sensor is located to the right of the maintenance assembly. The HP sensor sends an “On” signal when the carriage is in the home position.

Linear Encoder sensor This sensor is located on the back of the carriage (cutter housing section). This reflective photo sensor helps determine the exact carriage location by counting the clear and dark sections of the T­Fence. The Linear Encoder sends a pulse to the printer logic as a PTS (Print Timing Signal). The shaded sections have a distance equal to 180 dpi.

CARRIAGE & CARRIAGE COMPONENTS
The SP 7000 uses a special system to ensure the distance between the printhead nozzles and paper remains the same for all supported paper types. The carriage is composed of two sections; main carriage and subcarriage. The subcarriage can be moved closer or further away from the platen using the PG Cam which is driven by the PG Gear. The distance changes according to the position of the PG Cam.
The main carriage attaches to the CR Guide Rail using bearings and it supports the subcarriage. The subcarriage houses the printheads.

Printhead
Do not remove or loosen the screws that secure the CR guide rail, also do not remove the carriage. These parts are adjusted to 1/100th of a mm at the factory.
The printheads are the same type used in the EPSON Stylus Pro 9000 and EPSON Stylus Pro 5000. The design of the printhead holder is the same and the printheads are replaced in the same way. Therefore, after replacing the printheads, hardware and software adjustments are necessary to make sure the nozzles are lined up and to make sure ink dots are fired in the correct places. See Chapter 5 for details.
Other sensors and components attached to or related to the carriage are:
P-EDGE sensor This sensor measures the distance between the right and left edges of the paper. Where paper exists, the light emitted from the sensor is reflected back to the sensor. In this way the sensor determines the right and left paper-edge positions and the width of the paper. For more details, see “Paper size detection - right and left edges” on page 73.

Platen Gap home position flag The PG HP flag is located on the PG gear on the right side of the carriage. This gear connects with the PG gear assembly when the carriage is in the home position and the Pump motor is active. The PG origin sensor is a reflective sensor which detects when this flag is in the PG origin position.
Carriage home position flag The CR HP flag is located on the right side of the carriage. This flag cuts off the signal in the CR origin sensor. The CR origin sensor is a photo sensor which detects when the carriage is in the home position.
Cutter solenoid The solenoid is attached to the carriage on the opposite side of the home position (in the cutter housing) and it drives the cutter toward the paper. The spring drives the cutter back away from the paper. Also, the cutter solenoid is used to release the carriage lock. In order to cut roll paper evenly, the following method is used:
1) The cutter cuts from the left of center (when facing the printout) to the left edge.
2) The cutter cuts from several centimeters inside the right edge to the right edge.

3) The cutter cuts the remaining uncut portion, in the center, from the right side to the left.
Cutter height guide An important point is the cutter height guide which slides up and down. Its function is to stop the cutter guide at the correct height, which is determined at the factory. Due to this added feature, no carriage cover height adjustment is necessary, unlike the EPSON Stylus Pro 9000. Normally, you should not loosen or remove the screw that secures the cutter height guide.

2.2.2 Paper Feed Assembly

PF RAIL
The main paper feed components are the CR Guide Rail, the Grid Roller Assembly which is attached to the PF Rail, and the Secondary Roller Assembly which attaches to the back of the CR Guide Rail and faces the Grid Roller Assembly. The Grid Roller Assembly is made up of three equal lengths of rollers and their coupling.
The PF Motor is a DC Motor that is controlled by the software servo system, and the servo receives a pulse from the built-in optical rotary encoder. This rotary encoder allows for minute paper feeding.
The PF Roller torque is transferred through the PF Roller shaft edge (left frame), and turns the PF motor pinion gear and timing belt.

PAPER-FEEDING-RELATED SENSORS
The following sensors aid in the paper feeding process.
P_FRONT sensor This sensor is attached to the subplaten and is an optical (photo­reflective) sensor. This sensor detects the front edge of the paper after paper has been loaded but before it is set and ready to print.
P_REAR sensor This sensor is attached to the Upper Paper Guide and is an optical (photo-reflective) sensor. This sensor detects the rear edge of the paper and detects the front edge when the paper is first loaded in the paper path. The position of this sensor is stored in EEPROM.
P_EDGE sensor This sensor is attached to the Cutter Housing section on the carriage and detects the right and left edges of the paper. This sensor is also used to check for paper skew by checking whether the edges are in the same location at the top and bottom of a page.
P_THICK sensor This optical sensor physically gauges whether the paper falls into the normal/thin category or the thick category. For details, see “Platen Gap Mechanism” on page 70.

2.2.3 Maintenance Assembly

The maintenance assembly for the SP 7000 is similar to the maintenance assembly in the EPSON Stylus Pro 9000. If you are not familiar with the SP 9000, see the following for a detailed description.
See Figure 2-5 on page 59 for an illustration of the cleaning. The main components are:
Pump Assembly (head cleaner)
Pump Motor (stepping motor)
Cap Assembly (B head/C head independent)
Flushing Box
Waste Ink pads
The cleaning mechanism components are installed above the subframe and some are fixed on the main frame as shown below.
Flushing box
Pump
Motor
Pump
rotation = CW
Pump assembly (head cleaner)
When the head is in the capped position (valve closed), the pump motor creates a vacuum that sucks ink from the nozzles. This is used for removing ink from the nozzles and nozzle plate, initial ink charge, as well as cleaning. The waste ink flows through two small tubes to the waste ink pads.
Head cleaner
The head cleaner has felt on one side and rubber on the other, and is used to wipe or rub off ink and foreign materials from the nozzle surface.
Pump motor
Clockwise rotation = pump assembly drive for cleaning and so on
Counter clockwise rotation = platen gap adjustment
Cap assembly (one pad for each printhead)
When not printing, the printheads (should) rest on the cap assembly to make sure the nozzles don’t clog. Also, the printheads are in the capped position during ink charging, cleaning, and so on.
Flushing box
Flushing (dummy printing) is performed over the flushing box, and the flushed ink flows through the large diameter tube to the waste ink pads. Flushing fires a little ink to remove ink that may be drying on the nozzle surface; performed in between print jobs and sometimes during long print jobs.
Waste ink pads
The waste ink pads absorb ejected ink through the pump assembly ink tubes and the flushing box tubes.
When the pads near full, the LCD displays Maintenance Call 0100. When the pads are completely full, the LCD displays Service Call 00000100. The pads must be replaced at this time.

2.2.4 CR Lock Mechanism

The printer uses a spring to activate the carriage lock and an electromagnetic solenoid to release it. The spring forces the carriage lock up into the opening at the bottom of the subcarriage when the carriage is in the home position. However, when the CR Motor is running, the solenoid prevents the lock from engaging the carriage. To release the carriage from the capping position, the printer activates the cutter solenoid which pushes down the CR lock releasing the carriage.
To manually release the carriage when it is locked in the home position, press down the cutter and push the carriage to the left.
Operating Principles Description of Components 66
EPSON Stylus Pro 7000 Revision B

2.2.5 Ink Supply Mechanism

There is only one ink cartridge holder for all six cartridges. The design of the holder makes it quite easy to install and replace ink cartridges from the front of the printer. To prevent users from accidently installing a color ink cartridge in the wrong slot, the cartridges have slightly different designs.
Before moving the printer you or the user now has to flush the ink system as described in “Transportation Mode” on page 53.
CHECK
PO IN T
If you are familiar with the EPSON Stylus Pro 9000, you should quickly notice a few differences, including the missing ink valve, missing ink-type sensor, missing ink color sensor and missing ink ID sensor.
INK-RELATED SENSORS
The following sensors are located in the ink cartridge compartments.
Ink Cartridge sensor This optical sensor is built in all six ink cartridge slots.
When a cartridge is installed, switch = closed
When a cartridge is not installed, switch = open
Ink Low sensor This mechanical sensor (microswitch) is at the bottom of all six ink cartridge slots and detects when ink is running out.
When the I/C is nearly empty, the switch = open
When the I/C is not low (normal), the switch = closed

Operating Principles Description of Components 67
EPSON Stylus Pro 7000 Revision B
Cover open sensor
To ensure proper paper feeding and to prevent paper jams, the front cover must be closed during printing. There is one cover-open sensor that detects when the cover is open using an interlock switch, and this sensor is located near the left side of the main printer opening. When the cover is open, the relay that controls the current to the CR motor and PF motor cuts off the flow of that current. When this happens, the motors lose their electromagnetized state.

The sudden loss of current to the motors can cause problems and may even damage the motors or the printhead. To prevent this, a discharge from the capacitor connected to the current circuit is used to slow down the current before it is totally cut off. This process ensures that printing stops when the cover is open without causing any damage to printer parts.

2.3 Printer Mechanism Operation Outline

This section describes the various parts of the printer mechanism and how those parts work.

2.3.1 Carriage Mechanism

The carriage speed is determined by a software servo system. This software servo is a closed-loop system where the CR motor (a DC motor) must provide constant torque to keep the carriage speed even. For this purpose a timing fence (or step ruler) and an encoder sensor are employed to measure the carriage speed/location and to provide feedback to the motor controller accordingly.
Print Control
The carriage speed during printing is described below.
Table 2-3. Print Speed
Print Mode Carriage Speed
720dpi & Normal M/W 200cps
4 Pass FOL printing 300cps
unidirectional 400cps
the carriage travels. If the position of the carriage according to the Software Servo is different from the position according to the encoder, a fatal error occurs (Service Call 00010005).
See page 60 for details on carriage sensors and other parts.
Note: Due to the carriage’s quick acceleration process, even after the heads reach and maintain normal speed, they are not stable enough to print for the next 10mm.
Stop Control (stop position) The encoder determines the carriage position by counting the dark stripes on the Step Ruler. When the carriage reaches the predetermined position (depends on paper width), the carriage stops. To make sure the carriage has come to a complete stop, the printer checks the encoder for a certain time (in-position time-out) to make sure no signal is generated.
CR Motor Abnormality Detection The software servo sends a series of pulses to the CR Motor to drive the carriage a certain distance (depends on current operation, paper size, and so on). At the same time the encoder measures the distance
Operating Principles Printer Mechanism Operation Outline 69
EPSON Stylus Pro 7000 Revision B
PLATEN GAP MECHANISM
To produce high quality printouts, the printer must maintain a constant distance between the printhead nozzles and the paper. To do this the printer measures the thickness of the paper and adjusts the height of the carriage accordingly.
The carriage is composed of two parts; the main carriage which is secured to the CR guide rail via bearings, and the subcarriage which holds the printheads. The subcarriage is secured with a cam, and due to the cam’s shape, the subcarriage can be raised or lowered depending on the rotation of the cam. See Figure 2-17.
The platen gap adjustment is linear; the nozzle surface is constantly parallel to the paper surface.

When the carriage is in the home position, the PG motor can drive the cam via a series of gears. The motor turns counter clockwise to turn the cam and raise or lower the subcarriage to a set height. The actual platen gap position used during printing depends on the paper thickness as well as the control panel Platen Gap setting.
NOTE: You can manually set the platen gap. See Platen Gap in

EPSON Stylus Pro 7000 Revision B
PAPER FEED MECHANISM
The EPSON Stylus Pro 7000 feeds roll paper and cut-sheet paper using friction, and the two sensors along the paper feed path provide all necessary information for controlling the paper feed process. The sensors are the P-Rear sensor located on the right near the top of the paper feed path and the P-Front sensor located on the right under the carriage path. See Figure 2-12, "Paper Feed Sensors" on page 64. Another important point to remember about the paper-feed mechanism is the paper suction fans.
The paper suction fans are located behind the lower paper guide and are necessary to keep the roll paper flat against the lower paper guide, which prevents ink smears. The fans create a vacuum through the holes in the lower paper guide, pulling the paper flat against the guide. The strength of the vacuum is adjusted according to the media type setting.

Paper size detection - right and left edges
Before printing the printer needs to determine the distance from the right and left paper edges to the right frame and left frame (home position). As shown in the following flowchart, the printer flushes the heads to make sure no ink smears the paper as the printheads move across the paper. Then the carriage moves to where paper should definitely be (if loaded properly), near the vertical guide line. There the Paper Width sensor determines the brightness level (high) of the light reflected off the paper. (If no light is reflected, paper is not loaded or is not loaded properly and a “Reload Paper” error occurs.) The carriage moves back toward the home position, where paper definitely should not be if loaded properly, and determines the brightness level (low) when light is not

reflected off the paper. This procedure is necessary to set the high/low levels when adjusting for different media types, such as glossy or plain paper. Next the carriage moves from the home position toward the opposite frame and measures the distance from the home position to the opposite (right) edge of the paper according to the brightness high and low levels. If the paper edge has not been determined by a certain point (outside of the printheads’ print range), the paper is loaded too far to the right and a “Reload Paper” error occurs
Once the opposite-side paper edge has been found, the carriage moves from the opposite frame to the home position and measures the distance from the opposite frame to the HP-side (left) edge of the paper.

After paper is loaded in the printer, the printer performs the above left, right, and leading edge detection operations to make sure the paper is inside the printable range of the printheads. If any of these edges is outside of this area, a “Reload Paper” errors.
Basic loading procedure Make sure the left edge (near the HP) is lined up with the vertical line of holes in the Lower Paper Guide.
Normal loading area Paper loaded within 10mm of the center of the vertical line of holes in the Lower Paper Guide is considered in the printable zone; however, paper loaded outside that 10mm zone causes an error.
Paper skew In order to avoid printing on paper that is skewed or fed at a slant too far to the right or left, the printer detects the right and left edges at the leading edge of every page. If the printer determines that the paper is skewed 3mm or more compared to the previous page, a “Paper Not Straight” error occurs.
Basics The right and left edge positions are checked at the top of every page.
Degree of skew Any change in the edge position (from the originally detected position) over 3mm causes an error.

2.4.1 Power Supply Board Summary

Depending on the printer model, either 100V AC or 220V AC is supplied to the printer when the printer is plugged into an live outlet.
When plugged into a live power outlet, the power supply board is working.
CAUTION
To prevent over-current damage to the PS board, the following fuser is supplied on the PS board.
100V AC
The C299MAIN board has three control signals, described in detail in the table below.
Even after pressing the power switch to turn off the printer, power is supplied to and from the power supply board. During the power-down sequence, power is supplied to the CR motor to move the printheads to the capped position to prevent ink from clogging the nozzles.
Always turn off the printer using the power switch - do not remove the power cable from the wall outlet while the printer is on or while internal parts are moving.

1) The user loaded the leading edge of the paper too far into the printer. The printer can only reverse feed the paper a set distance, and if the paper is loaded too far, it will not reverse feed far enough.
2) The printer detected that the paper was loaded outside of the printable area/carriage path.
3) After printing, the printer detected that the paper is outside of the cutting area/carriage path.
4) The printer detected that the cut sheet loaded in the printer is too long/unsupported and could not be fully ejected. This may occur if roll paper is loaded but the control panel is set to cut sheets.
5) This error may occur after a Paper Not Cut error.
1-3 above) Correctly set the paper as described in the user’s guide. If the front edge is not clean and straight, cut it evenly.
4-5 above) For roll paper cut off the section of the paper that has been ejected and properly reload the paper. For cut sheets eject the remaining paper and select Sheets on the control panel or load supported paper depending on the cause of the error.
If after correctly reloading paper the same error occurs, check the operation and connection of the P-EDGE sensor located on the carriage.

Replace Ink Cartridge
The Ink End indicator for the incorrect slot (if an ink cartridge is installed in the wrong slot) or empty ink cartridge is on.
The ink-end error appears after the ink-end sensor detects the near-end condition and then a predetermined amount of ink is ejected. Also, if an ink cartridge that is already in the near-end condition is loaded, the printer will automatically produce this error.
In cases where an ink cartridge is loaded in the wrong slot or an unsupported ink cartridge is loaded, this error also occurs.
If an ink cartridge is empty, replace it with a new cartridge. Do not load a previously used ink cartridge; otherwise the ink counter will not work properly.
If the wrong cartridge is loaded, replace it with the correct cartridge.
If this error occurs even after replacing the old cartridge with a new cartridge, check the operation and connection of the corresponding ink-out sensor.
Do not insert used ink cartridges into the printer. Doing so will cause the ink counter to function improperly.
N/A LED indicator status
Details Only occurs during ink cartridge replacement.
Recovery
The Ink End indicators only function when the ink is low/empty,
when there is no ink cartridge, or when an ink cartridge is loaded
in the incorrect slot.
Finish replacing the ink cartridge(s) and close the ink cartridge
holder door.The printer automatically returns to the pre-error
state; i.e. “Ready” or “Paused”.

From Maintenance Mode 2 enter the Counter Init. Menu and initialize the Waste Ink counter and Cleaning counter.

SERVICE CALL 00000101

Problem A printer part has exceeded its useful life, and to prevent damage to other parts as well as abnormal operations/printouts, an error occurs. This error occurs when the CR Motor has reached 2.5 million passes, and this indicates the ink tubes should be replaced due to excessive wear and tear.
Solution To make sure the ink tubes are not worn out, verify no part of any of the tubes shows wear, is loose, or leaks ink anywhere, especially the tube area between the printheads and the ink pipes.

SERVICE CALL 00010000

Problem PF motor encoder check error The PF motor makes small revolutions clockwise and counter­clockwise. When it turns, the printer checks the rotary encoder (inside the motor) output signals to make sure the motor is turning at the correct speed/distance. If the encoder sends an incorrect signal, an error occurs.
Solution Make sure there is nothing blocking the grid rollers. If that does not solve the problem, check the PF motor encoder connection. If there still is a problem, try the following.
Check and adjust the PF Belt tension
Replace the PF motor
Replace the Main Board

3.4 General Errors

This section describes error that can be solved by the user.
CHECK
PO IN T

INK LOW

Problem An ink end sensor has detected that the corresponding ink cartridge is almost empty (ever ink cartridge has an ink level gauge). It is possible to print about 100% duty on B1 size paper with the remaining ink, but the cartridge should be replaced as soon as possible. If you re-install an ink cartridge that was detected as being in a “Near End” state, the status will immediately go to “Ink Out”. Only install new cartridges.
Solution Replace the ink cartridge.
By using “Check: Test” function in the built-in self-diagnostic mode, you can check control panel, sensors, encoders function. Refer to Chapter 5, Adjustment, for more details.

PAPER OUT

Problem
Paper is not loaded.
The rear edge of roll paper has been detected.
The print job using cut sheets is finished or the rear edge of cut-sheet paper has been detected.
Solution
If paper has run out, remove the printer paper and load new paper. If print data remains in the printer, the data will be printed.
If this error occurs even though paper is properly loaded, there may be something on the P-Rear sensor’s surface. Clean the sensor’s surface (hole in the Paper Guide, Upper) with a clean, dry cloth.
Use a clean, dry cloth when cleaning sensors; never use a wet cloth or soap.
CHECK
PO IN T
If for any reason you replace an ink cartridge before it reaches the ink-low or ink-out state with a new ink cartridge, you need to reset the ink counter using the control panel and Maintenance Mode 2.
Troubleshooting General Errors 99
EPSON Stylus Pro 7000 Revision B

LOAD XXX PAPER

Problem The selected paper source (according to the remote PP command) and the paper type selected on the control panel do not match.
Solution Load the correct paper or change the panel setting to match the type of paper loaded in the printer.

LOAD PAPER

Problem While paper is loaded, the Paper Release lever was pushed up to the Release position.
Solution
Make sure paper is loaded properly and push down the Release lever to lock the paper in place.
If this error occurs even when the lever is down, in the Lock position, there may be a problem with the Paper Release lever sensor. Check the sensor operation, sensor connection, and board.

PAPER JAM

Problem A paper jam occurs when during printing, paper feeding, or paper cutting the carriage is not able to move properly (due to paper catching on some part). The printer determines a paper jam has occurred if the P-Front sensor and P-Rear sensors are in the “on” state but the CR motor is out of step or has overcurrent.
Solution
After removing the paper stuck in the printer, the “TURN OFF AND ON” message appears on the display. The printer is ready after you turn the printer off and back on again.
If a paper jams occurs again after removing the original paper jam, check to make sure nothing is blocking the feed path or blocking the carriage.
Make sure the tabs of the Lower Paper Guide are inserted underneath the metal that supports the subplaten.

COVER OPEN

Problem The front cover is open. This error occurs when the cover is opened during carriage operation or a cleaning operation, causing the CR/PF operation and ink sequences to stop. If the cover is left open too long, the printheads may be damaged. (To avoid this problem, press the Pause button before opening the cover. But be aware that a stripe may appear on the printout indicating the different drying times.)
Solution
Close the cover as soon as possible.
If the cover is fully closed when this error occurs, make sure the left and right cover-open sensors are correctly installed and are operating properly.
