Clean the paper path with cotton swab or cloth. Remove foreign material from the purge unit caps, if any. Confirm the connection between the scanning unit and the logic board. Confirm that the timing slit strip film is free from damage or grease. Confirm the connection of each harness and the logic board. Examine the inside to confirm that no parts are damaged, and the rollers are clean. Perform the button and LCD test in the service mode, and confirm that the LCD is displayed without any segments missing. Confirm the connection between the operation panel, the scanning unit, and the logic board. Check the operation of the moving parts (such as purge unit, carriage unit, and paper feeding mechanism) between the logic board and the power supply unit. If the counter value is 7% or more, also replace the ink absorber kit (QY5-0181) when replacing the logic board ass'y. *1: Before replacement of the logic board ass'y, check the ink absorber counter value (by service test print or EEPROM information print). The RAM error occurred in the RAM check at hard.
