J92-01, J92-02 when making 1:2 or 2:2 copies.

CAUSE: Failed or worn ADU conveyance rollers and/or worn sensor actuators.
SOLUTION: Replace conveyance roller/2 (# 55VA47400), conveyance roller/3 (# 55VA47480), conveyance roller/4 (# 55VA47410), and conveyance roller/5 (# 55VA47670). At the same time the actuators for PS8, PS9, and PS13 in the ADU should be replaced with the modified actuators (# 55VA47821). In addition, all ADU driven roller bushings and shafts should be cleaned. It is recommended that all the above listed parts be replaced at the same time due to the amount of disassembly required.
Note: This problem can occur on machines that have two million or more copies/prints.

J92-02 or J93-02 when duplexing. Paper accordion jams at the ADU reversal roller.

CAUSE: The inner portion of the drive gear for the ADU reversal roller has worn. The excessive play of the hub causes the gear to bind on the shaft.
SOLUTION: Replace the ADU conveyance gear (# 55VA77650).


Intermittent J92-2 when duplexing.

CAUSE: The ADU DB failed.
SOLUTION: Replace the ADU DB (# 55VA-9071).
Note: It is not recommended to check the board. It may check good, but after running for a short period of time, it fails.


J92-02 when duplexing.

CAUSE: Worn conveyance roller/1.
SOLUTION: Replace conveyance roller/1 (p/n 55VA47660) and ADU lock gear/1 (# 55VA77600)


J92-02 when duplexing.

CAUSE: The second paper feed clutch failed.
SOLUTION: To check second paper feed clutch operation, perform the following:
1. Access the 47 mode (power the machine ON while holding down on the 4 and 7 keys), output code 025.
2. Press the print button and the paper feed clutch should activate. Press the STOP button and the clutch should be released.
3. If none of the above occurs, replace the paper feed clutch (# 55VA82010).


J92-02 when making 1:2 or 2:2 copies.

CAUSE: Paper dust build up on the black photosensor sheet/heat insulation sheet positioned above the reversal sensor (PS58), resulting in erratic paper detection by the reversal sensor.
SOLUTION: To clean the black photosensor sheet/heat insulating sheet, perform the following:
1. Power the copier OFF.
2. Remove the fusing unit.
3. Remove the fan mount cover (# 55VA47100)
4. Remove the fusing unit base cover, which is depicted in the 7075 Parts Catalog (1/2000) on page 74. However, since it is not available as a replacement part it has no part number associated with it.
5. Thoroughly, clean the black photosensor sheet/heat insulating sheet, which is attached to the bottom of the fusing unit base plate. Replace the black photosensor sheet/heat insulation sheet (p/n 55VA47750) as necessary.


J92-2 only when selecting 1:2 or 2:2 copy modes using 8.5x11 paper.

CAUSE: A failed fixing exit sensor (PS2) or a bind in its actuator.
SOLUTION: Verify the operation of the sensor actuator and repair any binding. If needed, replace the exit sensor (# 55VA85520)


J92-02 will not clear

CAUSE: Failed second paper feed clutch.
SOLUTION: Replace the second paper feed clutch (# 55VA82010) as needed


J92-02 with paper jamming at the entrance of the ADU reverse unit or the lower section of the conveyance unit. The paper may, or may not, be caught between the conveyance rollers. These jams may be more prevalent on higher volume machines.

CAUSE: The pin groove of the ADU reverse/exit motor (M5) is worn due to repeated rotation/reverse operation.
SOLUTION: Replace the ADU drive motor (# 55VA-0411).
Note: The pin and gear is included with the new motor.

If that doesn't work, replace the following ADU rollers: 55VA47400, 55VA47480, 55VA47410 and 55VA47670.
