Troubleshooting 3 - 101
Incomplete image transfer to paper
All of the image does not transfer to the
paper. Part of the image remains on the
drum to be picked up by a chase page or
the next print, usually caused by
insufficient or non-uniform drum oiling.

Step Question and Actions
1
Media that is not smooth or too light can cause this problem, use higher quality or
heavier media.
2
Inspect the drum-maintenance drawer. Is the wiper blade damaged? If
necessary, replace the drum-maintenance drawer.
3
Inspect the drum-maintenance system. Does the drum maintenance roller
contain sufficient oil? Replace the drum-maintenance roller, if necessary.
4
Are the drum-maintenance cam roller and electric clutch operating correctly?
Test them using diagnostics.
5
Ensure the left and right drum-maintenance actuators operate correctly when
lifted by the cams of the drum maintenance cam roller.
6
The drum may be too warm, verify the drum temperature using diagnostics.
Ensure the drum temperature sensor is properly positioned and has no
contamination between it and the drum surface.
7
Verify the paper preheater temperature using diagnostics.
8
If the problem persists, replace the printhead.
