Removal procedures
Notes:
• Remove the waste toner bottle, color toner cartridges, imaging unit, and media tray before removing other
printer parts. The imaging unit should be carefully set on a clean, smooth, and flat surface. It should also
be protected from light while out of the printer.
• Unless otherwise stated, reinstall the parts in reverse order of removal.
• When reinstalling a part held with several screws, start all screws before final tightening.
• Some removal procedures require removing cable ties. You must replace cable ties during reassembly to
avoid pinching wires, obstructing the paper path, or restricting mechanical movement.
