2. Copier adjustment

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 130mm from the both ends of the developing doctor as shown.

3)Push the developing doctor in the arrow direction, and tighten the developing doctor fixing screw. (Perform the same procedure for the front and the rear frames.)

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>

Developing doctor gap

Both ends (20mm from the both ends): 1.5±0.1mm

C (Center)(150mm from the both ends): 1.5±0.1mm

(2) MG roller main pole position adjustment

1)Remove and separate the waste toner box and put the developing unit 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.
