Service manual

28. Rotate the development roller gear with the development roller rotation handle
[A] until the developer is spread evenly on the development roller surface.
NOTE: Rotate the development roller rotation handle only in the direction
shown in the diagram above.
29. "Tap" the development supply funnel [B] with the handle of a screwdriver
[C] to ensure all of the developer falls into the unit.
30. Remove, clean, the funnel and reinstall the developer cover (1 screw).
NOTE: 1) Before reinstalling the developer cover, clean any developer
spills on the sponge seal around the opening with a vacuum
cleaner. If any developer remains on the sponge seal, a gap
may be eroded in the sponge by the spilt developer. Toner
and developer may then leak through this gap.
2) When installing the developer cover, take care not to misalign
the sponge [F] or developer may spill out.
3) Before tightening the screw [D], ensure the two tabs [E] are
completely inserted into the slots and the screw holes are aligned
correctly.
4) Be sure to use the correct screw [D] (M4 x 6) to attach the
developer cover. If a screw longer than screw [D] is used, the
development paddle will be damaged by the longer screw.
5) Hold the developer cover in position when tightening the
screw. This is to prevent the screw holes from misaligning.
6) Never overtighten the screw [D]. If the screw is overtightened,
the development unit’s screw hole (made of aluminum) may be
damaged and the entire development unit may need to be
replaced.
