Causes: Registration sensor detects paper feed condition at out of specified timing during switchback.
Remedy: < User Check > - Check whether the recording paper being used is within the specification. 1 Registration actuator caught on the surrounding parts Set the registration actuator into place. 2 Registration sensor defective Replace the registration sensor PCB. 3 Main PCB defective Replace the main PCB.
Code: 1500
Description: Paper jam during duplex ejecting
Causes: Recording paper is not able to be ejected since it is longer than 840 mm when ejecting the paper. (The registration sensor stays in the paper feeding condition during ejecting.)
Remedy: < User Check > - Remove the jammed paper. - Check whether the recording paper being used is within the specification. 1 Foreign materials in the recording paper path Remove foreign materials. 2 Registration actuator caught on the surrounding parts Set the registration actuator into place. 3 Main PCB defective Replace the main PCB.
Code: 1700
Description: Recording paper size error (duplex-printing/duplex-copying)
Causes: - The paper width detected by the paper width sensor or the paper length detected by the registration sensor was not suitable for duplex printing.
Remedy: < User Check > - Check whether the recording paper being used is within the specification. - Check that dark recording paper is not used. 1 CR encoder strip stained Clean the CR encoder strip. 2 PF encoder disk stained Clean the PF encoder disk and flushing guide. 3 Registration actuator caught on the surrounding parts Set the registration actuator into place. 4 CR encoder strip defective Replace the CR encoder strip. 5 PF encoder disk defective Replace the PF encoder disk. 6 Registration sensor defective Replace the registration sensor PCB. 7 Paper width sensor defective Replace the carriage PCB ASSY. 8 Paper feed motor defective Replace the paper feed motor. 9 Main PCB defective Replace the main PCB.
Code: 1800
Description: Paper jam during duplex-printing
Causes: Registration sensor does not detect paper feed within specified pulse numbers in the second side paper re-feed.
Remedy: < User Check > - Remove the jammed paper. - Check whether the recording paper being used is within the specification. - Check that recording paper are not curled, wrinkled or wet. 1 Foreign materials in the duplex print paper path Remove foreign materials. 2 Registration actuator caught on the surrounding parts Set the registration actuator into place. 3 Registration sensor defective Replace the registration sensor PCB. 4 Switchback roller defective Replace the switchback roller. 5 Drive frame ASSY defective Replace the maintenance unit. 6 Main PCB defective Replace the main PCB.
Code: 2000
Description: Cannot identify a black ink cartridge.
Causes: The ink cartridge detection sensor and the ink remaining sensor are detecting.
Remedy: < User Check > - Check if incompatible ink cartridge is loaded. - Reload the ink cartridge. - Replace the ink cartridge. 1 Each ink cartridge sensor or ink cartridge IC chip PCB defective Replace the ink refill ASSY. 2 Main PCB defective Replace the main PCB.
Code: 2001
Description: Cannot identify a yellow ink cartridge.
Causes: The ink cartridge detection sensor and the ink remaining sensor are detecting.
Remedy: < User Check > - Check if incompatible ink cartridge is loaded. - Reload the ink cartridge. - Replace the ink cartridge. 1 Each ink cartridge sensor or ink cartridge IC chip PCB defective Replace the ink refill ASSY. 2 Main PCB defective Replace the main PCB.
