A. Process section
(1) Developing doctor gap adjustment
1) Loosen the developing doctor fixing screw A.
2) Insert a thickness gauge of 1.5mm to the three positions at 20mm
and 150mm from the both ends of the developing doctor as shown.
3) Push the developing doctor in the arrow direction, and tighten the fixing
screws of the developing doctor in the sequence of 132
33.
4) Check the clearance of the developing doctor. If it is within the
specified range, then fix the doctor fixing screw with screw lock.
* When inserting a thickness gauge, be careful not to scratch the
developing doctor and the MG roller.
<Adjustment specification>
(2) MG roller main pole position adjustment
1) Remove the DV front cover, and put the developing tank on a flat
surface.
2) Tie a string to a needle or a pin.
3) Hold the string and bring the needle close to the MG roller
horizontally. (Do not use paper clip, which is too heavy to make a
correct adjustment.) (Put the developing unit horizontally for this
adjustment.)
4) Do not bring the needle into contact with the MG roller, but bring it to
a position 2 or 3mm apart from the MG roller. Mark the point on the
MG roller which is on the extension line from the needle tip.
5) Measure the distance from the marking position to the top of the
doctor plate of the developing unit to insure that it is 18mm.
If the distance is not within the specified range, loosen the fixing
screw A of the main pole adjustment plate, and move the adjustment
plate in the arrow direction to adjust.
