[ Case in the field ]
Field Remedy
1. Check whether jam code 0105 was recorded in the jam history or E110-0110 was in the error log. If either of
them was recorded, inspect the fixing/feeder sensor flag to make sure that mylar is attached to it. If not, replace
the sensor flag with a new type.
2. If mylar is attached or the new type of the sensor flag has already been installed, clear DCON in service mode
[COPIER> Function> CLEAR> DC-CON].
3. If the symptom still recurs, swap the laser units for all colors.
