To place the rear stacker in its down position, place the front mounting
pins beneath the stacker guides and slide the rear mounting pins into
the lower stacker grooves. (Adjust the letter C labeled on the rear
stacker to the letter C labeled on the printer. Insert the stacker in the
direction of the arrow.) The rear stacker is put in this position when a
cut sheet feeder is to be attached to the rear of the printer or using the
front tractor.
