Streaks on the copies

[Norm36]

Streaks on the copy in the right third of the page when fed through the feeder.  There are no steaks when the original is laid on the glass.  The glass has been cleaned and as much of the feed mechanism as I can reach without dissembling the feed mechanism.

The smaller glass on the left side, you didn't clean it enough.

Use a sheet with streaks, place it near the smaller glass and the streaks will align with dirt on the glass. Do not remove or damage plastic foil over smaller glass.
