ERROR CODE and TROUBLESHOOTING
The paper which has passed through the fuser unit does not
reach the fuser transport sensor.
• Connector check (CN491, CN497)
• Board check
• Sensor check
(Perform the input check: 03-[ALL]OFF/[2]/[C], 03-
[COPY]ON/[5]/[F])
• Connector check
• Harness check
• Connector check (CN309)
• Harness check
• Board check
• Check the gap between the separation plate and the fuser
belt.
(Refer to "6.7.4 Gap adjustment for separation plate".)
• Paper transport check
• Gear check
• Roller check
Adjust the margin with 05-4402 (Leading edge position
adjustment) to "Color: 5.5 mm".
(Specification Black: 4.2 mm / Color: 5 mm)
• Use A3/LD paper
• Black solid image on 10 mm of the leading edge
Refer to "6.1.1 Image Related Adjustment".
Change the 2nd transfer bias offset value as shown below
and then check if there are still jams.
Change the default value 5 of each code below to 6 or 7.
Color: 05-2934 Subcode: 0, 7
Color: 05-2935 Subcode: 0, 7
Black: 05-2936 Subcode: 0, 7
Black: 05-2937 Subcode: 0, 7
If the leading edge of paper clings to the 2nd transfer roller
and causes paper jamming, change the 2nd transfer roller
bias correction factor of the leading/trailing edge of the paper.
(The larger the value, the smaller the transfer voltage of the
leading/trailing edge of the paper.)
Codes to be changed (Initial value of the transfer bias of
the leading/trailing edge of the paper: 0)
• Color mode print (top side): 05-2938-*
• Color mode print (back side): 05-2939-*
• Black mode print (top side): 05-2940-*
• Black mode print (back side): 05-2941-*
Sub codes:* -> Plain paper: 0, Recycled paper: 7
Notes:
After these codes are changed, perform solid duplex-
printing and check that there is no faint or void image
on the leading/trailing edge of the paper.
