Removal Procedures
CAUTION: Remove power from the printer before you connect or
disconnect any cable or electronic board or assembly for personal
safety and to prevent damage to the printer. Use the hand grips on
the side of the printer. Make sure your fingers are not under the
printer when you lift or set the printer down.
Note: 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.
