2. LIST OF ERROR DISPLAY / INDICATION

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 and its solution are displayed on the LCD in text and by icon.

2) Messages during printing from a computer are displayed on the MP driver Status Monitor.

3) Error codes are printed in the "operator call/service call error record" area in EEPROM information print.

Buttons valid when an operator call error occurs:

1) ON/OFF button: To turn the machine off and on again.

2) OK button: To clear and recover from an error. In some operator call errors, the error will automatically be cleared when the cause of the error is eliminated, and pressing the OK button may not be necessary.

3) Stop/Reset button: To cancel the job at error occurrence, and to clear the error.

the counter value is 7% or more, also replace the ink absorber kit (QY5-0181) when replacing the logic board ass'y.

[See 3-3. Adjustment / Settings, (5) Service mode, for details.]

*2: Replace the print head only after the print head deep cleaning is performed 2 times, and when the problem persists.

Notes on replacement

- Before removal of the logic board ass'y, remove the power cord, and allow for approx. 1 minute (for discharge of capacitor's accumulated charges), to prevent damages to the logic board ass'y.

- Before replacement, check the ink absorber counter value (by service test print or EEPROM information print). If the value is 7% or more, also replace the ink absorber kit (QY5-0181) when replacing the logic board ass'y.

[See 3-3. Adjustment / Settings, (5) Service mode, for details.]

*1: General notes:

- Make sure that the flexible cables and wires in the harness are in the proper position and connected correctly.

[See 3-2. Special Notes on Repair Servicing, (5) Flexible cable and harness wiring, connection, for details.]

- Do not drop the ferrite core, which may cause damage.

- Protect electrical parts from damage due to static electricity.

- Before removing a unit, after removing the power cord, allow the machine to sit for approx. 1 minute (for capacitor discharging to protect the logic board ass'y from damages).

- Do not touch the timing slit strip film, timing slit disk film, and timing slit disk eject film. No grease or abrasion is allowed.

- Protect the units from soiled with ink.

- Protect the housing from scratches.

- Exercise caution with the red screws, as follows:

i. The red screws of the paper feed motor may be loosened only at replacement of the paper feed motor unit (DO NOT loosen

them in other cases).

ii. DO NOT loosen the red screws on both sides of the main chassis, securing the carriage shaft positioning (they are not

adjustable in servicing)

After replacement:

1. Perform the print head alignment in the user mode.

- Service test print
