I use this printer only occasionally hence I don’t know when the problem started.
When I use the auto-feed to copy a document or a several paged document it creates a line on the copy. This is a very distinct line 1/16th of an inch (2 MM) wide from one side of the page to the other.
When I place the document on the flat-bed screen the line does not appear.
I have cleaned and examined everything I can see.
Any suggestions.
