Logic board ass'y

QM2-3022

- 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 waste ink amount (by service test print or EEPROM information print).

[See 3-4. Verification Items,

(1) Service test print

, or (2)

EEPROM information print,

for details.]

After replacement:

1. Initialize the EEPROM.

2. Set the destination in the EEPROM.

3. Reset the waste ink counter.

4. Correct the CD / DVD and automatic print head alignment sensors.

5. Check the ink system function.

6. Adjust the line feeding.

[See 3-3. Adjustment / Settings, (8) Service mode, for details of 1 to 6]

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

*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, (3) 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 and timing slit disk 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)
