6.13CHARGE CORONA WIRE HEIGHT ADJUSTMENT
NOTE: a) The charge corona wire height adjustment should be
done only when the front end block is replaced.
b) Before replacing the front end block of the charge
corona unit, adjust the uneven exposure with the
exposure adjusting plates and make a copy sample
with the test chart for the reference.
1. Remove the wire cleaner and the front end block cover [A] (1
plastic screw) from the charge corona unit.
2. Adjust the gap "X" (between the wire height adjusting block and
the screw holder edge) to 8.0 mm by turning the wire height
adjusting screw [B] as shown in the illustration.
3. Reassemble the charge corona unit and set it in the copier.
4. Make copies with the test chart and compare the front and rear
gray scales with those of the reference copy made before
replacing the front end block. Adjust the corona wire height by
turning the wire height adjusting screw, if necessary.
Turning the screw clockwise decreases the image density at the
front side.
Turning the screw counterclockwise increases the image density
at the front side.
