13.3 FUSING ENTRANCE GUIDE SHIFT MECHANISM
The entrance guide [A] for this machine is adjustable for thick or thin paper.
For thin paper, move the entrance guide up (this is the standard position).
This slightly lengthens the paper path which prevents the paper from
creasing in the fusing unit.
For thick paper, move the entrance guide down. This is because thick paper
does not bend as easily, and is therefore less prone to creasing. Also, the
lower setting allows more direct access to the gap between the hot and
pressure rollers. This prevents thick paper from buckling against the hot
roller, which can cause blurring at the leading edge of the copy.
There are three screw holes on each side for securing the entrance guide.
Normally, the center screw hole on each side is used. The other screw holes
are spare in case the center holes get damaged.
