PRO-100: Paper keep slides as it's going in and jams

[ahmadka]

I bought a PRO-100 about 1.5 years ago (after my previous one broke down) that has been rarely used in the last year or so. A few days ago I tried printing something from it about like 8-9 months and the paper got jammed from the rear tray as it was going in. I have tried doing the 'Roller Cleaning' for rear tray, but it doesn't help. The paper also slides and gets jammed as it's going in.

Any ideas how to fix this ?

Greetings,

Maybe its just the angle of the photo, but the feeding mechanism doesn't appear to be straight in the second photo.  Maybe it just looks like this?  Can you confirm?
