Misregistration
This is when the distance from the lead edge
of the image t o the lead edge of the media i s
not within specification.
Offsetting
This is the transfer of toner from the copy t o
the fuser heat roll. Sometimes the toner is
transferred back t o the copy or consecutive
copies.
Resolution
The uniformity or clarity of fine line detail.
Residual lmage
This is an image that is repeated on t o the
same copy or consecutive copies. The image
can either be a ghosting of the original image
or a toner image. The repeated image i s
usually spaced 10.4 inches (264mm) from the
original image. This problem can be caused by
poor cleaning of the drum, a drum that is
fatigued, or offsetting by the fuser.
Smear
This is any copy defect that occurs in the cross-
process direction (from left t o right sides).
