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.
2. Remove the developing unit cover and blade cover, and then place the developing unit on a level surface.
3. Attach a piece of string to a sewing needle or pin.
4. With the string in hand, bring the needle closer to the DV roller while keeping the needle parallel with the roller. (Do not use a clip, which does not accurately indicate the position.)
5. Keeping the needle 2 to 3 mm off the DV roller surface, mark the DV roller surface at an extension of the needle tip. (Do not let the needle tip contact the DV roller.)
6. Measure the distance between the marking on the DV roller and leading edge of the DV doctor, and make sure that it is 19±0.5mm. If this requirement is not met, do the following steps.
   
7. Remove the front cover.
8. Loosen the fixing screws of the developing roller main pole adjusting plate, and make adjustments by moving the adjusting plate in the arrow direction.
   

Repeat steps 3 to 6 until the developing roller main pole meets the positional requirement
