ERROR CODE and TROUBLESHOOTING
The paper after the 2nd transfer is clinging to the transfer belt,
or a paper jam occurred between the registration roller and
the paper clinging detection sensor.
• Sensor check
(Perform the input check: 03-[ALL]OFF/[9]/[D])
• Connector check
• Harness check
• Motor check
(Perform the output check: 03-128/528)
• Connector check
• Harness check
• Connector check (CN514, CN515)
• Board check
• Connector check (CN537, CN538, CN539)
• Board check
• Gear check
• Roller check
If jams occur on the back side in duplex printing, change the
media type mode to the recycled paper mode, and then check
if there are still jams. (When this type of jam occurs on heavily
curled paper during duplex printing, the jam may be resolved
by selecting the recycled paper mode.)
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.
