ADJ M1 DV doctor gap adjustment

This adjustment must be performed in the following cases:

• When the developing unit is disassembled.

• When the print density is low.

• When there is a lot of toner dispersion abnormally.

1) Remove the developing unit from the copier, and remove the

developing unit cover and the blade cover.

2) Loosen the DV doctor fixing screw A.

3) Insert a 0.525 thickness gauge at the point of 40mm ∼ 70mm from

the DV doctor edge.

4) Push the DV doctor in the arrow direction and tighten the DV doc-

tor fixing screw.

(Perform the same procedure for the front and the rear frame

simultaneously.)

5) Check that the clearance is 0.525 ±0.03mm at two positions which

are 40mm ∼ 70mm from the both sides of the DV doctor.

∗ When inserting the thickness gauge, be careful not to scratch the

DV doctor and the MG roller.

ADJ M2 DV roller main pole position

adjustment

This adjustment must be performed in the following cases:

• When the developing unit is disassembled.

• When the print density is low.

• When there is a lot of toner dispersion abnormally.

1) Remove the developing unit cover and the blade cover, and place

the developing unit on a flat surface.

2) Tie a string to a needle or a pin.

3) Hold the string and put the needle horizontally and move it toward

the MG roller. (Do not use a clip which is too big to have a correct

position.)

4) With the needle tip at 2 ∼ 3mm from the MG roller surface, mark

the point on the surface which is on the extended line of the

needle tip. (Do not make contact between the needle tip and the

MG roller.)

5) Measure the distance between the marking position and surface P

of the developing unit, and check that the black unit is 13mm,

color unit 24mm.

If the distance is not as specified above, loosen the fixing screw A

of the main pole adjustment plate, and move the adjustment plate

in the arrow direction to adjust.
