Description: Memory input interface problem Reading-in of an image does not complete within 10 s of the start of image transmission.
Causes: Defective main PCB.
Remedy: Replace the main PCB 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: C1010
Description: Upper lift motor problem • When the upper drawer is inserted, the upper lift limit switch does not turn on within 6 s of the upper lift motor turning on and the upper lift limit switch does not turn on by turning off the upper lift motor for 200 ms and retrying twice. • During copying, the upper lift limit switch 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 upper lift motor connector terminals. Defective upper lift limit switch. Poor contact of the upper lift limit switch 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 CN13-B9 on the main PCB goes low when the upper lift limit switch is turned off. If not, replace the upper lift limit switch. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
Code: C1020
Description: Lower lift motor problem • When the lower drawer is inserted, the lower lift limit switch does not turn on within 6 s of the lower lift motor turning on and the lower lift limit switch does not turn on by turning off the lower lift motor for 200 ms and retrying twice. • During copying, the lower lift limit switch does not turn on within 200 ms of the lower lift motor turning on.
Causes: Broken gears or couplings of the lower lift motor. Defective lower lift motor. Poor contact of the lower lift motor connector terminals. Defective lower lift limit switch. Poor contact of the lower lift limit switch connector terminals.
Remedy: Replace the lower lift motor. Check for continuity across the coil. If none, replace the lower lift motor. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check if CN13-B15 on the main PCB goes low when the lower lift limit switch is turned off. If not, replace the lower lift limit switch. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
Code: C1030
Description: Desk upper lift motor problem • When the upper drawer of the paper feed desk is inserted, the desk upper lift limit switch does not turn on within 6 s of the desk upper lift motor turning on and the desk upper lift limit switch does not turn on by turning off the desk upper lift motor for 200 ms and retrying twice. • During copying, the desk upper lift limit switch does not turn on within 200 ms of the desk upper lift motor turning on.
Causes: Broken gears or couplings of the desk upper lift motor. Defective desk upper lift motor. Poor contact of the desk upper lift motor connector terminals. Defective desk upper lift limit switch. Poor contact of the desk upper lift limit switch connector terminals.
Remedy: Replace the desk upper lift motor. Check for continuity across the coil. If none, replace the desk upper lift motor. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check if CN1-5 on the desk main PCB goes low when the desk upper lift limit switch is turned off. If not, replace the desk upper lift limit switch. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
Code: C1040
Description: Desk lower lift motor problem • When the lower drawer of the paper feed desk is inserted, the desk lower lift limit switch does not turn on within 6 s of the desk lower lift motor turning on and the desk lower lift limit switch does not turn on by turning off the desk lower lift motor for 200 ms and retrying twice. • During copying, the desk lower lift limit switch does not turn on within 200 ms of the desk lower lift motor turning on.
Causes: Broken gears of couplings of the desk lower lift motor. Defective desk lower lift motor. Poor contact of the desk lower lift motor connector terminals. Defective desk lower lift limit switch. Poor contact of the desk lower lift limit switch connector terminals.
Remedy: Replace the desk lower lift motor. Check for continuity across the coil. If none, replace the desk lower lift motor. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable. Check if CN1-7 on the desk main PCB goes low when the desk lower lift limit switch is turned off. If not, replace the desk lower lift limit switch. Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace the cable.
