When I manually feed paper or envelopes through my HP 4250tn, the sheet or envelope gets pulled to the left as it feeds. The image is printing crooked on the sheet as a result - or so I think. When you look at the printed sheet the image as angled 2 or 3 degrees from right to left. I had replaced the rollers with a rebuild kit a few years ago. Can anyone tell me how to resolve this printing crooked issue I am having.
