3.  Slightly open the redrive door at the back of the printer (see picture below), lift the left side of that door until the left side is free, then lift and clear the right side to completely remove the door.

5. Remove the 2 mounting screws labeled "A" in picture below, and then release the 2 mounting latches labeled "B" in picture below, then remove the redrive assembly.
