Sharp MXM700N

This adjustment is needed in the following situations:

• The developing unit has been disassembled.
• The print density is low.
• The toner is excessively dispersed.

1. Remove the developing unit of the machine.
2. Remove the developing unit cover and blade cover.
3. Loosen the DV doctor fixing screws.
4. Manually turn the DV roller to align the marking on the DV roller surface with the DV doctor position.
5. Insert a 0.525mm clearance gauge in between the DV roller and DV doctor so that the gauge is positioned at a distance of 40 mm to 70 mm from the DV doctor end face.
   
6. Tighten the DV doctor fixing screws while pressing the DV doctor in the arrow direction. (This should be done for both front and rear frames.)
7. On both sides of the DV doctor and at its center, make sure
   that the DV doctor gap is 0.525±0.03.

When inserting a clearance gauge, take care not to damage the DV doctor or MG roller

Repeat steps 2 to 6 until the DV doctor gap meets the requirement.
