The entrance guide [A] has two holes on the rear side of the entrance guide
to adjust for thick or thin paper. Normally, the upper screw hole [B] is used.
For thin paper, move the entrance guide up by securing it with screw hole [B].
This slightly lengthens the paper path, which prevents the paper from
creasing in the fusing unit.
For thick paper, move the entrance guide down (use the lower screw hole).
This is because 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. Also, thick paper does not bend as easily, and is therefore less prone
to creasing.
