Having problem with document feeder. When original is run thru doc feeder, copy comes out stretched and text reveresed always at the last quarter of the page. One time copy will be fine next one will be wrong.

When running copies straight off the glass copies fine, except sometimes comes out with a half inch wide and 4 inches long toner scuff about 1-2 inches from lead edge of copy which is very intermittent.

Also got an error code E5-55, when trying to run the Doc feeder one time
and when I went to look it up in the service manual its not even listed.

Polished target glass and cleaned feed and forward rollers on Doc feeder
and seems to run smoothly no hesitations acts normal. Doc feeder is a model FA-A888. Checked drum, drum blade, and developer unit and seem fine. Very puzzled. Any suggestons????

The toner scuff that you are refering to is often caused by the cleaning blade/tension spring...Th.
