6.7 ENTRANCE GUIDE PLATE HEIGHT ADJUSTMENT
NOTE: Do not loosen or remove the entrance guide plate [A] except to
replace it. The entrance guide plate height (gap between the leading
edge of the entrance guide plate mylar and drum) is adjusted at the
factory with special equipment.
Before removing the entrance guide plate, mark its original position
as shown. Position the new entrance guide plate so that the edge of
the plate is aligned with the mark.
If the original position of the entrance guide plate was not marked
before the plate was loosened or removed, adjust its position as
follows:
ADJUSTMENT STANDARD: GAP "X" Front 2.65 ± 0.1 mm
Rear 3.25 ± 0.1 mm
1. Set the gap "X" between the edge of the bracket [B] and the entrance
guide plate adjustment standard using the thickness gauge as shown in
the illustration. Then, tighten both the front and rear screws.
2. Make sure that the leading edge of the entrance guide plate mylar does
not contact the drum after the TC/SC corona unit is installed.
