This seems to be fault in the transport of the paper in the rollers. So if you have used any adhesive sticker printing, it is possible that some glue has got clogged into the rollers. If not there can be some jammed paper in the rollers or the mechanism.
So start this work only if you are mechanically able with the right tools.
Remove the covers to get access to the mechanism . Remove the motor drive assembly , the fitting of the motor to the mechanism. Once this is removed the rollers can be turned manually so that you will be able to feed a paper to see the progress of the movement while studying if there is any obstruction or damage to the paper.
There is a in-detect sensor, usually an opto-coupler , make sure this is not clogged or dirty as this IR detection feeds the signal to the processor for starting the motor drive feed.
Reassemble but make sure the rollers are aligned to be in equal gap to feed the paper without a side pull. Now you must print and see if the fault has changed. If not repeat the above work to confirm the area of obstruction.
