7.2 FUSING ENTRANCE GUIDE

[A]
The entrance guide [A] for this machine is adjustable for thick or thin paper.
With thin paper, set the entrance guide in the upper position. This slightly
lengthens the paper path which prevents the paper from creasing in the
fusing unit. With thick paper, set the entrance guide in the lower position.
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.
In this model, the transfer belt improves paper transport and the paper path
to the fusing entrance is stabilized. This reduces the chance of paper
creasing due to paper skews in the fusing unit.
Therefore, the guide plate standard position is the lower position. (Standard
position on previous models was the upper position).
Since there are very few reasons to change the guide plate position, there is
no guide plate position adjustment lever for customer use.
