• Code: 17-20
• Description: The tray 2 vertical transport sensor (PS19) is not turn ON even after the set period of time has elapsed after the paper feed sensor (PS3) turns ON.
• Causes: • Transport motor (M3) • Paper feed sensor (PS3) • Tray 2 vertical transport sensor (PS19) • LU drive board (LUDB) • PC control board (PCCB) • MFP board (MFPB)
• Remedy:

• Code: 20-01
• Description: The registration sensor (PS1) is not turned ON (unblocked) even after the lapse of a given period of time after the paper has turned ON the tray 2 vertical transport sensor (PS19).
• Causes: • Transport motor (M1) • Tray 2 vertical transport clutch (CL2) • Registration clutch (CL4) • Registration sensor (PS1) • Tray 2 vertical transport sensor (PS19) • Front side board (FRB) • MFP board (MFPB)
• Remedy:

• Code: 20-02
• Description: For paper fed from the tray 2, tray 3, tray 4, LCC or LCT, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop.
• Causes: • Transport motor (M1) • Tray 2 vertical transport clutch (CL2) • Registration clutch (CL4) • Registration sensor (PS1) • Tray 2 vertical transport sensor (PS19) • Front side board (FRB) • MFP board (MFPB)
• Remedy:

• Code: 20-21
• Description: <When PC-110 or PC-210 is installed> The tray 2 vertical transport sensor (PS19) is not turned ON even after the lapse of a given period of time after the tray 3 vertical transport sensor (PS113) has been blocked by a paper. <When PC-410 is installed> The tray 2 vertical transport sensor (PS19) is not turned ON even after the lapse of a given period of time after the vertical transport sensor (PS133) has been blocked by a paper.
• Causes: <When PC-110 or PC-210 is installed> • Transport motor (M1) • Tray 3 vertical transport motor (M112) • Tray 2 vertical transport clutch (CL2) • Tray 2 vertical transport sensor (PS19) • Tray 3 vertical transport sensor (PS113) • MFP board (MFPB) • PC control board (PCCB) <When PC-410 is installed> • Transport motor (M1) • Vertical transport motor (M132) • Tray 2 vertical transport clutch (CL2) • Tray 2 vertical transport sensor (PS19) • Vertical transport sensor (PS133) • MFP board (MFPB) • PC control board (PCCB)
• Remedy:

• Code: 20-22
• Description: The tray 3 vertical transport sensor (PS113) is not turned ON even after the lapse of a given period of time after the tray 4 vertical transport sensor (PS123) has been blocked by a paper.
• Causes: • Tray 3 vertical transport motor (M112) • Tray 4 vertical transport motor (M122) • Tray 3 vertical transport sensor (PS113) • Tray 4 vertical transport sensor (PS123) • PC control board (PCCB)
• Remedy:

• Code: 30-03
• Description: The leading edge of paper is not turned ON (unblocked) the paper exit sensor (PS3) since the paper feeding is started.
• Causes: • Transport motor (M1) • Fusing motor (M3) • Registration clutch (CL4) • Registration sensor (PS1) • Paper exit sensor (PS3) • Front side board (FRB) • MFP board (MFPB)
• Remedy:

• Code: 32-01
• Description: The ADU paper passage sensor/1 (PS40) is not turned ON (unblocked) even after the lapse of a given period of time after the reverse sequence is started.
• Causes: • Fusing motor (M3) • Reverse motor (M4) • ADU transport motor (M5) • Paper exit clutch (CL8) • Paper exit sensor (PS3) • ADU paper passage sensor/1 (PS40) • Gate switch solenoid (SD3) • Front side board (FRB) • MFP board (MFPB)
• Remedy:

• Code: 32-05
• Description: The paper exit sensor (PS3) is not turned OFF (blocked) even after the lapse of a given period of time after the paper has turned ON (unblocked) PS3.
• Causes: • Fusing motor (M3) • Reverse motor (M4) • ADU transport motor (M5) • Paper exit clutch (CL8) • Paper exit sensor (PS3) • ADU paper passage sensor/1 (PS40) • Gate switch solenoid (SD3) • Front side board (FRB) • MFP board (MFPB)
