Description: RDS communication error - Timing & Condition - The main control board receives no response from RDS when accessing it. Even when this error is detected, the copier does not show the SC code and this SC code is not logged. (Copier function is still working.)
Causes: • Poor connection of harness, opticalfiber cable, or damaged • Defective line adapter • Defective I/F board RDS/LCT • Defective main control board
Remedy: 1. Check the connector of the harness and optical-fiber cable is properly set on the I/F board RDS/LCT and main control board or check if they are damaged. 2. Check and/or change the setting of the line adapter or replace it. 3. Replace the I/F board RDS/LCT. 4. Replace the scanner IPU board.
Code: SC690
Description: Application selection error - Timing & Condition - When the main CPU communicates with CPUs on other PCBs, main CPU does not receive response from others.
Causes: • Scanner IPU firmware upgrade • Poor connection of connectors • Defective main scanner IPU board • Defective main control board • Defective TD sensor I/F board 1 • Main board(s) of options
Remedy: • This SC code will be displayed when the scanner IPU firmware is changed. Turn off the main switch and disconnect the IC card; then, turn on the main switch. 1. Check if the connectors on the main control board, sub scanner IPU board, TD sensor I/F board 1, and the main board on each option equipped are properly connected. 2. Replace the defective board(s).
Code: SC721
Description: Sorter: Bin motor error - Timing & Condition - The signal from the wheel sensor does not change at certain timing. When this error detected twice, this SC code is displayed.
Causes: • Poor connection of connector • Defective sensor • Defective motor • Bin position error • Defective main board
Remedy: 1. Check if the connectors of the wheel H.P. sensor and bin motor are properly connected. 2. Replace the wheel sensor (Input check: SP 5-803- 124/125). 3. Check if the bins are properly positioned. 4. Replace the bin motor (Output check: SP 5-804-124). 5. Replace the main board.
Code: SC722
Description: Sorter: Jogger motor error - Timing & Condition - The jogger H.P. sensor does not activate within the timing programmed. When this error detected twice, this SC code is displayed.
Causes: • Poor connection of connector • Defective jogger H.P. sensor • Defective jogger motor • Defective main board
Remedy: 1. Check if the connectors of the jogger H.P. sensor and jogger motor are properly connected. 2. Replace the jogger H.P. sensor. (Input check: SP 5- 803-128) 3. Replace the jogger motor. (Output check: SP 5-804- 131) 4. Replace the main board.
Code: SC724
Description: Sorter: Grip motor error - Timing & Condition - The grip H.P. sensor does not activate within the timing programmed. When this error detected twice, this SC code is displayed.
Causes: • Poor connection of connectors. • Defective grip H.P. sensor / grip unit H.P. sensor • Defective grip motor • Defective main board
Remedy: 1. Check if the connectors of the grip H.P. sensor, grip unit H.P. sensor, and grip motor are properly connected. 2. Replace the sensor(s). (Input check: SP 5-803- 129/137) 3. Replace the grip motor. (Output check: SP 5-804-127) 4. Replace the main board.
Code: SC725
Description: Sorter: Stapler motor error - Timing & Condition - The stapler H.P. sensor does not activates within the timing programmed. When this error detected twice, this SC code is displayed.
Causes: • Staple jam • Excessive sheets of paper stapled • Poor connection of connectors • Defective stapler H.P. sensor • Defective staple motor • Defective main board
Remedy: 1. Remove the staple(s) jammed if it causes SC. 2. Instruct user how many sheets can be stapled as maximum. 3. Check if the connectors of the staple H.P. sensor and/or staple unit motor are properly connected. 4. Replace the stapler H.P. sensor. (Input check: SP 5- 803-131) 5. Replace the stapler motor. (Output check: SP 5-804- 129) 6. Replace the main board
