Hello... I would like to try to help with the problem.
First thing I would try is, using a flashlight or other light source, and seeing if, further into the paper path, where the paper feeds into the printer, whether there is any obstruction(s) visible on the side that lags behind when paper is pulled in. If so, remove it carefully with a tweezers.
Second, make sure that the blank paper is held snugly (but without bending the paper either) with the movable paper guide on one side holding it into a neat stack. Illustrations may help:
Which shows in (A), the paper guide being adjustable after it is pinched, and it should be moved snug up against the side of the stack of paper.
The stack of paper should not be so thick as to rise above the line at (2).
(3) Set the paper thickness lever properly according to the media .
Paper other than envelopes-> Left side
Envelopes/T-Shirt Transfers -> Right side
(Also, if none of that remedies things, take the paper out again, look down at that roller that grabs and feeds the paper: is it rough on the surface? or is it tightly against its seat at both ends? if space shows through at one end, that would explain the misfeed.)
