077-129 Regi Sensor On Jam (Duplex Wait)
BSD-ON:CH8.3, CH4.1, CH10.4
During the paper stop at the invert wait position at Duplex print, the Regi Sensor did not turn
ON within the specified time after the Duplex Clutch On.
Cause/Action
Check the following:
• The Regi Sensor (Input Check [071-105]) for operation failure. (PL 15.1)
• The Main Drive Motor (Output Check [042-001]) for operation failure. (PL 3.1)
• The Invert Motor (Output Check [071-005] (Dup)) for operation failure. (PL 17.1)
• The Dupex Clutch (Output Check [071-002]) for operation failure. (PL 14.4)
• The Exit Roll, Duplex Roll 1, 2, and Pinch Roll for transportation failure due to contamina-
tion, wear, and deterioration.
• The Drive Gear and Belt for wear and damage.
• A paper transportation failure due to foreign substances on the paper path.
• Usage of out of spec paper.
If no problems are found, replace the ESS/MCU PWB. (PL 18.1)
077-212 Tray Module Reset Fail
BSD-ON:CH3.2
The Tray Module was detected to be reset.
Cause/Action
1. Turn the power OFF and ON.
2. Check voltages of the following pins:
•STM PWB J541C-5 (+5VDC)
•STM PWB J541C-8 (+24VDC)
3. Turn OFF the power and check the connection between the ESS/MCU PWB J413 and
the STM PWB J541C for open circuit, short circuit, and poor contact.
4. If no problem is found, replace the following parts in sequence:
•STM PWB (PL 10.6)
• ESS/MCU PWB (PL 18.1)
077-300/301/305 Front Cover/Left Hand Cover/STM Cover
Open
BSD-ON:CH1.5, CH1.6
The applicable Cover Switch was detected to be open.
Cause/Action
1. Check the applicable Cover Switch for operation failure.
• Front Cover Switch (Input Check[071-301]) (PL 19.1)
• Front Cover Interlock Switch and L/H Cover Interlock Switch (Input Check[071-300])
(PL 19.1, PL 14.1)
• STM Left Cover Switch (Input Check[072-300]) (PL 10.4)
2. Check the applicable Cover Switch for damage and mismatch.
3. If no problem is found, replace the following parts:
• ESS/MCU PWB (Front Cover Open, L/H Cover Open) (PL 18.1)
• STM PWB (STM Left Cover Open) (PL 10.6)
077-900/901/904 Regi Sensor/Fusing Unit Exit Sensor/
Feed Out Sensor 2 Static Jam
BSD-ON:CH8.3, CH10.3, CH8.2
Paper was detected by the applicable sensor at Power ON, M/C Stop, or Interlock Close.
Cause/Action
1. Check the applicable sensor for remaining paper, the Actuator for return failure, contami-
nation on sensor, and etc.
2. Check the applicable sensor for operation failure.
• Regi Sensor (Input Check[071-105]) (PL 15.1)
• Fusing Unit Exit Sensor (Input Check[071-106]) (PL 7.1)
• Feed Out Sensor 2 (Input Check[072-104]) (PL 10.5)
3. If no problem is found, replace the following parts:
• ESS/MCU PWB (Regi Sensor, Fusing Unit Exit Sensor) (PL 18.1)
• STM PWB (Feed Out Sensor 2) (PL 10.6)
