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 )
