5.9 INADEQUATE FUSING OF UNEVEN COPY SURFACE
- Phenomenon -
The fusing unit, an oilless mechanism, uses a smooth teflon fusing roller.
This roller sometimes misses indented areas on the paper surface.
- Explanation -
Instruct the customer to use paper that has an even surface.
5.10 GAP OR OVERLAPS IN OVERLAY COPYING
- Phenomenon -
Absolute precision is difficult to achieve
when placing an overlay original on the
exposure glass and/or inputting the desig-
nated area. In overlay mode, a small gap
or overlaps of up to 5 mm/0.2” may ap-
pear between the designated area and
the surrounding area.
Horizontal gap
- Explanation -
Instruct customers to leave some space free around the designated area.
5.11 MULTIPLE PASSES THROUGH FUSING UNIT
- Phenomenon -
When paper is transported three or more times through the fusing unit,
paper creasing or misfeeds often occur.
- Explanation -
Instruct customers not to feed copies that have been through the
duplex/overlay process once.
