Errors and warnings are displayed by the following ways:

1. Operator call errors are indicated by the Alarm LED lit in orange, and the error messages are displayed by the printer driver Status Monitor.

2. Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service call error record" area in EEPROM information print

Buttons valid when an operator call error occurs:

1. Power button: To turn the printer off and on again.

2. Resume/Cancel button: To cancel the job at error occurrence, and to clear the error.

4-4. Special Notes on Servicing

(1) Print head problem (smeared printing, uneven printing, non-ejection of ink, etc.)

For problems that are supposed to be caused by the print head (smeared printing, uneven printing, or nonejection of ink, etc.), print the nozzle check pattern in the user mode to determine whether the print head is faulty or not.

< Procedures >

1) In the user mode, print the nozzle check pattern.

2) If there is a missing portion in the printed pattern, perform the print head cleaning (2 times at the maximum), and print the nozzle check pattern again (in the user mode).

3) If the problem persists even after the print head cleaning is performed 2 times, perform the print head deep cleaning, then print the nozzle check pattern again (in the user mode).

4) If the problem is still not resolved, i) turn off the printer and leave it for 24 hours or longer, ii) perform the print head cleaning, and iii) print the nozzle check pattern again (in the user mode).

(2) Paper feed motor adjustment

1) When attaching the motor, fasten the screws so that the belt is properly stretched (in the direction indicated by the blue arrow in the photo below).

2) After replacement, be sure to perform the service test print, and confirm that no strange noise or faulty print operation (due to dislocation of the belt or gear, or out-of-phase motor, etc.) occurs.

The screws securing the paper feed motor may be loosened only at replacement of the paper feed motor unit. DO NOT loosen them in other cases.

(3) Carriage unit replacement

To replace the carriage, the carriage shaft must be removed from the main chassis (by removing the screws).

Before removing the screws, put a mark on the main chassis to indicate the carriage shaft position. (The screws are either the red ones or the regular ones.)

After replacing the carriage, return the carriage shaft to the original position while aligning the shaft to the mark on the chassis.

The screws on the carriage shaft adjustment plate may be loosened only at replacement of the carriage unit. DO NOT loosen them in other cases.

(4) Platen unit replacement

When attaching the platen unit, perform adjustment to protect the eject roller shaft from bending due to weight of the spur unit. (The screws to be removed and re-fastened for adjustment are either the red ones or the regular ones.)

<Adjustment procedures>

1) Without the spur unit, slide the adjustment plate upward (as shown in the left photo) until it slightly contacts the eject roller shaft (as shown in the right photo).

Be cautious not to push up the eject roller shaft.

2) Fasten the screws to secure the plate in the adjusted position.

3) After adjustment, be sure to perform the service test print, and confirm that no strange noise or faulty print operation (uneven printing or print head contacting the paper) occurs.

The screws securing the adjustment plate may be loosened only at replacement of the platen unit. DO NOT loosen them in other cases.

(5) Ink absorber counter setting

Before replacement of the logic board, check the ink absorber counter value, and register it to the replaced new logic board. (The value can be set in 10% increments.)

In addition, according to the ink absorber counter value, replace the ink absorber (ink absorber kit). When the ink absorber is replaced, reset the applicable ink absorber counter (to 0%).

- How to check the ink absorber value and the way to set the ink absorber counter:

In each step below, confirm that printing is performed properly and the printer operates properly without any strange noise.

EEPROM information print

Nozzle check pattern print

<Check point>

- The pattern must be printed properly.

Communication with a connected computer

<Check point>

- Via USB connection to the computer, printing from the computer must be performed properly

(paper feeding from the rear tray and from the front tray respectively).

<Additional verification to be made>

- For repair of a specific problem, confirm the applicable specific function in the user mode.

PictBridge, CD / DVD printing

PictBridge CD / DVD printing

Power-off in the service mode

<Check point>

- The paper lifting plate must be in the raised position.

External and internal appearance

<Check point>

Packaging

- No grease, oil, or smearing on the timing slit strip film.

- No lifting of the platen ink absorber.

- No foreign material or dislocation of any part inside the printer.

- No damage or scratches that will affect the functionality.

<Check point> See 5. PRINTER TRANSPORTATION .

5. PRINTER TRANSPORTATION

TABLE OF CONTENTS

This section describes the procedures for transporting the printer for returning after repair, etc.

1) In the service mode, press the Power button to finish the mode, and confirm that the paper lifting plate of the rear tray is raised.

2) Keep the print head and ink tanks installed in the carriage.

See Caution 1 below.

3) Turn off the printer to securely lock the carriage in the home position. (When the printer is turned off, the carriage is automatically locked in place.)

See Caution 2 below.

(1) If the print head is removed from the printer and left alone by itself, ink is likely to dry. For this reason, keep the print head installed in the printer even during transportation.

(2) Securely lock the carriage in the home position, to prevent the carriage from moving and applying stress to the carriage flexible cable, or causing ink leakage, during transportation. Make sure that the carriage is locked in place at power-off.

- If the print head must be removed from the printer and transported alone, attach the protective cap (used when the packing was opened) to the print head (to protect the print head face from damage due to shocks).

- If the packing material that fixed the carriage from the factory is still available, re-use it to fix the carriage (to prevent the carriage unlocked during transportation).
