SERVICE REMARKS23 April 1993
1.6 DEVELOPMENT UNIT
1. Be careful not to nick or scratch the development roller sleeves.
2. Place the development unit on a sheet of paper after removing it from the
copier. This prevents any small metal objects (staples, clips, E-rings, etc.)
from being attracted to the development roller and getting inside the unit.
3. Be careful not to bend terminals on the rear side.
4. Clean the drive gears after removing the used developer.
5. Never load different types of developer or toner into the development unit.
Doing so will cause poor copy image and toner scattering inside the
copier.
6. Developer initial setting is necessary when new developer is loaded.
Do not perform the developer initial setting with used developer.
Do not make any copy before initial setting.
7. When removing the development unit, push it to the right to prevent the
OPC drum from being scratched by part of the development unit.
8. The doctor gap and the development rollers position must not be
adjusted in the field as they are precisely adjusted at the factory using
special tools. Do not loosen any screws with white paint.
9. Before pulling out the development unit, disconnect two connectors.
10. When pulling out the development unit, do not pull the knob.
11. When setting the development unit in the machine, do not forget to set
the two connectors.
1.7 TRANSFER BELT UNIT
1. Do not touch the transfer belt with oily bare hands.
2. When servicing the transfer belt cleaning unit, be careful not to damage
the edge of the cleaning blade.
3. Apply setting powder or toner to the new cleaning blade.
