1. Isolate printing functionality by performing a PAPER PATH TEST.

Lift the latch on the printer front door and open the door.
CAUTION: Do not place anything on the surface of the transfer unit. Also, do not touch the transfer unit contacts located on the left side of the unit.

3. Remove the transfer unit (callout 1 in photo below) by grasping the blue handles (callout 2 in the photo below) on both sides of the transfer unit. With your right thumb, press and hold the lever on the right side handle (callout 3 in the photo below) then lift the handle up (callout 4 for direction), followed by lifting the left side (callout 5 in the photo below). Set the unit aside on a flat surface. Be careful not to touch the black, upper surface (transfer belt) of the unit.
