FUSING ENTRANCE GUIDE

The entrance guide [A] for this machine is adjustable for thick or thin paper by

changing the screw position from the upper to the lower.

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. In addition,

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 stabilizes the paper

path to the fusing entrance. This reduces the chance of paper creasing due to

paper skews in the fusing unit.

Use the screws to adjust the guide plate position. Since there are very few reasons

to change the guide plate position, there is no guide plate position adjustment lever

for customer use.

The markings on the entrance guide are different for different regions. Each

entrance guide is designed for the paper width that is normally used in each region,

for optimum prevention of creasing.
