Service manual, section 6.8.7
ˆ
This machine uses a brush and counter blade.
ˆ
The brush removes the toner, and the blade removes bits that the brush missed.
ˆ
The toner collection coil carries the toner in the cleaning unit back to the
development unit.
ˆ
The blade moves from side to side.
ˆ
At the end of every copy job, the drum reverses for 10 mm to scrape toner off the
edge of the cleaning blade.
ˆ
In addition, SP2-506 can be programmed to have this done at intervals during long
copy runs. The default setting is disabled.
¾
If enabled, an ID sensor pattern for toner supply control will be made at the
same time.
