Description: Paper jam during duplex-printing The recording papers are fed in reverse on the platen when switchback drive is started, triggering switchback sensor as paper feeding condition.
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. - Check that recording paper is loaded correctly in the paper tray. 1 Foreign materials in the duplex print paper path Remove foreign materials. 2 Switchback outer paper guide not mounted in place Set the switchback outer paper guide into place. 3 Switchback actuator caught on the surrounding parts Set the switchback frame ASSY into place. 4 Switchback sensor defective Replace the switchback sensor PCB. 5 Main PCB defective Replace the main PCB.
Code: 0E00
Description: Defective during duplex-printing Switchback 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 Switchback actuator caught on the surrounding parts Set the switchback frame ASSY into place. 2 Switchback sensor defective Replace the switchback sensor PCB. 3 Main PCB defective Replace the main PCB.
Code: 1300
Description: Defective during duplex-printing Registration sensor detects paper feed condition at out of specified timing during switchback.
Remedy: < User Check > - Check that recording paper is not loaded in the MP tray and/or manual feed slot. - 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 Switchback actuator caught on the surrounding parts Set the switchback frame ASSY into place. 3 Registration sensor defective Replace the registration sensor PCB. 4 Main PCB defective Replace the main PCB.
Code: 1500
Description: Paper jam during duplex ejecting 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) - Paper width is narrower than 95.5 mm (detection by paper width sensor) - Paper length is longer than 245.9 mm (detection by registration sensor) - Paper length is shorter than 143.5 mm (detection by registration sensor)
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 Switchback actuator caught on the surrounding parts Set the switchback frame ASSY into place. 5 CR encoder strip defective Replace the CR encoder strip. 6 PF encoder disk defective Replace the PF encoder disk. 7 Registration sensor defective Replace the registration sensor PCB. 8 Paper width sensor defective Replace the carriage PCB ASSY. 9 Paper feed motor defective Replace the paper feed motor. 10 Main PCB defective Replace the main PCB.
Code: 1800
Description: Paper jam during duplex-printing. 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 Switchback actuator caught on the surrounding parts Set the switchback frame ASSY into place. 4 Registration sensor defective Replace the registration sensor PCB. 5 Switchback roller defective Replace the switchback roller. 6 Drive frame ASSY defective Replace the maintenance unit. 7 Main PCB defective Replace the main PCB.
