Description: LED print head 1 (EEPROM) communication error [magenta drum The LED print head 1 (EEPROM) the magenta drum unit does communicate with the engine controller PWB (A0004) normally.
Causes: Defective LED print head 1. Installing the LED print head, which is incompatible with the printer specification. Defective engine controller PWB (A0004). Defective LED print heads relay PWB (A0176). Defective harness (S03214) between engine controller PWB (A0004) and LED print heads relay PWB (A0176), or poor contact of the connector terminals. Defective FFCs (S03011) between LED print head 1 and LED print heads relay PWB (A0176), or poor contact of the FFC terminals.
Remedy: Defective LED print head 1. Replace the LED print head 1. See page 1- 5-15. Installing the LED print head, which is incompatible with the printer specification. Install the compatible LED print head to the black drum unit. Defective engine controller PWB (A0004). Replace the engine controller PWB (A0004). Defective LED print heads relay PWB (A0176). Replace the LED print heads relay PWB (A0176). Defective harness (S03214) between engine controller PWB (A0004) and LED print heads relay PWB (A0176), or poor contact of the connector terminals. Check the continuity of the harness (S03214), check the insertion of YC3 of the engine controller PWB (A0004), if there is trouble, remedy or replace. Defective FFCs (S03011) between LED print head 1 and LED print heads relay PWB (A0176), or poor contact of the FFC terminals. Check the connection of the FFCs with the magenta drum unit and the printer main unit, check the continuity of the FFCs (S03011), check the connection of the LED print head 1, if there is trouble, remedy or replace.
