1.5
ERASE LAMP
1. A narrower lead edge erase margin increases the possibility of fusing
jams. The margin should be at least 1.0 mm.
2. After cleaning the erase lamp unit, rub it lightly with your finger to
discharge any static electricity on the unit surface.
3. Make sure that the erase lamp setting (SP84) is correct. Otherwise, ID
sensor abnormal condition will occur.
1.6
DEVELOPMENT UNIT
1. Be careful not to nick or scratch the development roller sleeve.
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 the bias terminals.
4. Clean the drive gears after removing the used developer.
5. Never load different types of developer or toner (black and color) into the
development unit. Doing so will cause poor copy image and toner
scattering inside the copier.
6. Developer initialization is necessary when new developer is loaded.
a) Black developer initialize (SP65)
b) Color developer initialize (SP10)
7. Adjust the black development bias voltage (SP37) together with the
exposure lamp voltage (SP48) if necessary. This should be done only
when the drum initial setting (SP66) is performed. The results of adjusting
the black bias voltage with the used drum will be compensated by the
exposure lamp voltage when the VL pattern detections are performed.
The color development bias voltage (SP79) can be adjusted any time.
8. The doctor gaps must not be adjusted in the field as they are strictly
adjusted at the factory.
