Description: Side deck communication problem • An error code from the side deck is detected eight times in succession. No communication: there is no reply after 3 retries. Abnormal communication: a communication error (parity or checksum error) is detected five times in succession.
Causes: Poor contact in the connector terminals. Defective main PCB. Defective side deck main PCB.
Remedy: Check the connection of connectors CN13 on the main PCB and CN3 on the side deck main PCB, and the continuity across the connector terminals. Repair or replace if necessary. Replace the main PCB and check for correct operation. Replace the side deck main PCB and check for correct operation.
Code: C0440
Description: Finisher communication problem • An error code from the side deck is detected eight times in succession. No communication: there is no reply after 3 retries. Abnormal communication: a communication error (parity or checksum error) is detected five times in succes-sion.
Causes: Poor contact in the connector terminals. Defective main PCB. Defective finisher main PCB.
Remedy: Check the connection of connectors CN24 on the main PCB and CN2 on the finisher main PCB, and the continuity across the connector terminals. Repair or replace if necessary. Replace the main PCB and check for correct operation. Replace the finisher main PCB and check for correct operation.
Code: C0610
Description: Bitmap (DIMM) problem • There is a problem with the data or address bus of the bitmap DRAM.
Causes: Defective main PCB. DIMM installed incorrectly. Defective DIMM.
Remedy: Replace the main PCB and check for correct operation. Check if the DIMM is inserted into the socket on the main PCB correctly. Replace the DIMM and check for correct operation.
Code: C0630
Description: DMA problem • DMA transmission of compressed, decompressed, rotated, relocated or blanked-out image data does not complete within the specified period of time.
Causes: Defective main PCB.
Remedy: Replace the main PCB and check for correct operation.
Code: C0640
Description: Hard disk drive problem • The hard disk drive cannot be accessed.
Causes: Poor contact of the hard disk drive connector terminals. Defective hard disk drive. Defective main PCB.
Remedy: Check the connection of connectors CN2 on the main PCB and hard disk drive, and the continuity across the connector terminals. Repair or replace if necessary. Replace the hard disk drive and check for correct operation. Replace the main PCB and check for correct operation.
Code: C1010
Description: Upper lift motor problem [Drawer 1] • When the drawer 1 is inserted, the lift limit switch 1 does not turn on within 5.5 s of the upper lift motor turning on. • During copying, the lift limit switch 1 does not turn on within 200 ms of the upper lift motor turning on.
Causes: Broken gears or couplings of the upper lift motor. Defective upper lift motor. Poor contact of the lift motor 1 connector terminals. Defective lift limit switch 1. Poor contact of the lift limit switch 1 connector terminals.
Remedy: Replace the upper lift motor. Check for continuity across the coil. If none, replace the upper lift motor. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check if CN 7-6 on the engine PCB goes low when the lift limit switch 1 is turned off. If not, replace the lift limit switch 1. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
