A:Answer Hi GetsGuy. Typically, this happens when the paper is unevenly stacked in the feeder. Please be sure all pages are aligned evenly, then make sure paper guides on your LaserJet Pro M15w keep the stack aligned - not too loose but resting against the edge of the paper in the feed tray. If this does not solve the problem, there may be another issue. In that case, please reach out to HP Tech Support at https://bit.ly/3mULd9E . You can also reach them by phone at 1-800-474-6836.
