A supply item is installed incorrectly, causing repeated jams. Verify that all print cartridges, the transfer unit, and the fuser are correctly installed. You are reloading paper that has already passed through a printer or copier. Do not use paper that has been previously printed on or copied. An input tray is loaded incorrectly. Remove any excess paper from the input tray. Be sure that the paper does not exceed the maximum stack height mark in the input tray. See Configuring trays. Paper is skewed.
