- Causes: • LED exposure unit • CCD board (CCDB) • Scanner drive board (SCDB)
- Remedy: 1. Check the connectors on CCDB or MFPB for proper connection and correct as necessary. 2. Replace SCDB 3. Replace the CCD unit.
- Code: D-1
- Description: Split line detect (front side). • While recovering from the power save mode or when the main power switch and power key are ON, it detects whether or not stain exist at the original reading glass when the DF is closed. This warning will be displayed if the original is set to DF when stain exist. • The thin line detection level and the warning display can be changed by [Service Mode] -> [System 2] -> [ADF Scan Glass Contamin. Set.] -> [Front Side].
- Causes: • Front side cleaning motor (M8) • Front side cleaning home sensor (PS18) • DF control board (DFCB)
- Remedy: 1. Wipe clean the glass surface of the original reading glass. 2. Check the front side glass cleaning roller unit for proper installation and correct if necessary. Clean the front side glass cleaning roller unit if dirty. 3. Select [Service Mode] -> [System 2] ->[ADF Scan Glass Contamin. Set.] -> [Front Side], and change the setting. 4. Check the DFCB connector for proper connection and correct as necessary. 5. M8 operation check 6. Replace the front side glass cleaning roller unit. 7. Replace DFCB.
- Code: D-3
- Description: Split line detect (back side). • While recovering from the power save mode or when the main power switch and power key are ON, it detects whether or not stain exist at the back side original scanning section (CIS) when the DF is closed. This warning will be displayed if the original is set to DF when stain exist. • The thin line detection level and the warning display can be changed by [Service Mode] -> [System 2] -> [ADF Scan Glass Contamin. Set.] -> [Back Side].
- Causes: • CIS module (CIS) • DF power supply (DFPU) • Dual scan image processing board (DSIPB)
- Remedy: 1. Wipe clean the CIS glass surface. 2. Check the back side glass cleaning roller unit for proper installation and correct if necessary. Clean the back side glass cleaning roller unit if dirty. 3. If there is a problem in the CIS module connection, correct the faulty connection. 4. Replace CIS. 5. Replace DFPU. 6. Replace DSIPB.
- Code: P-16, P-18
- Description: • PC charge cleaning trouble 1 <P-16> • PC charge cleaning trouble 2 <P-18>
<P-16> Charging cleaner home sensor is not transmitted even after the specified time has passed while the charging cleaner material or serrate electrode material is moving forward.
<P-18> Charging cleaner return sensor is not interrupted even after the specified time has passed when the charging cleaner material or serrate electrode material is moving forward. * Under the situation above occurs, control will be switched to the return operation after the warning is given. When the charging cleaner home sensor is not interrupted after the specified time has passed during the return operation, trouble code C-2101 will be given. - Causes: • Drum unit • Charge cleaning motor/K (M15) • Charging cleaner home sensor (PS43) • Charging cleaner return sensor (PS44) • PH relay board (PHRYB) • MFP board (MFPB)
- Remedy: 1. PS43 I/O check, sensor check 2. PS44 I/O check, sensor check 3. M15 operation check 4. Replace the drum unit. 5. Replace M15. 6. PHRYB F2 conduction check. 7. Replace PHRYB. 8. Replace MFPB.
- Code: P-27
- Description: Secondary transfer ATVC failure. An abnormal average value is detected during an adjustment of the second transfer ATVC value.
- Causes: • High voltage unit/2 (HV2) • MFP board (MFPB) • Image transfer entrance guide • 2nd transfer assy • Transfer belt unit
- Remedy: 1. Check the contact between the roller opposed to the 2nd transfer roller in the transfer belt unit and the grounding terminal. Clean the joint or correct if necessary. 2. Check the image transfer entrance guide for proper installation and correct if necessary. 3. Check that the spring does not come off during the pressure operation of the transfer roller and correct if necessary. 4. Check the contact at the joint of the 2nd transfer assy and HV2. Clean the joint or correct if necessary. 5. Replace the transfer belt unit. 6. Replace HV2. 7. MFPB F12E conduction check 8. Replace MFPB.
- Code: P-32
- Description: Heating roller temperature sensor/1 temperature detection failure (bizhub 808/758) Fusing belt temperature sensor/1 temperature detection failure (bizhub 958, bizhub PRO 958)
bizhub 958, bizhub PRO 958 • During warm up, the temperature detected by the fusing belt thermistor/1 exceeded the warm up complete temperature of the heating roller for over the predetermined value, and stayed for a predetermined period of time. • When the predetermined period of time had passed after the warm up became complete, detected temperature of the fusing belt thermistor/1 exceeded the temperature detected by the fusing belt temperature sensor/1 for over the predetermined value for more than the predetermined period of time. • While printing, temperature detected by the fusing belt thermistor/1 exceeded the temperature detected by the fusing belt temperature sensor/1 for more than the predetermined value for a predetermined period of time. • This warning indicates that condensation or dirt on the fusing belt temperature sensor/1 was detected, and the alternate temperature control is being conducted. With condensation, the warning is cleared when the condensation is detected to be removed. When the dirt on the sensor is detected, it is considered as a failure and the trouble code C-392A is issued.

- Remedy: 1. Wipe the TEMS1 clean of dirt if any. <Cleaning procedure> • Clear away a dirt or a foreign object on the sensor with a cotton swab. • When a dirt is left even if you cleaned the sensor by above procedure, clear away a dirt or a foreign object on the sensor using a cotton swab dampened with the alcohol. And, wipe off the sensor with a dry cotton swab afterwards. 2. Check the connection of the fusing unit. 3. Replace the fusing unit.
