Cleaning Systems
Residual toner is removed from the Photoreceptor Drum by using a Preclean Corotron, a
Cleaning Blade and a Brush. The IBT uses a camming Cleaning Blade. A Waste Toner Auger
system is used to transport the waste toner to a Waste Toner Bottle.
In addition, there is a Developer Waste Bottle wh
ic
h accumulates overflow developer from the
Developer Assemblies. This is a part of the Trickle System. Refer to that section for more infor-
mation on that function.
The carrier beads that come back off each Developer Roll during t
he developm
ent process are
recycled into the corresponding Developer Housing Assembly and are remixed with the other
developer for reuse.
Photoreceptor Cleaning
The components of the cleaning system for the Photoreceptor Drum includes: (See Figure 1.)
• Bead Pickup Roll (BPO)
• Preclean Corotron (PCC)
• Photoreceptor Clean Brush
•Flicker Bar
• Blade
• Auger
•Duct
• Erase Lamp (Located in the machine, not mounted on Photoreceptor Drum)
After the Drum has transferred the image to the IBT
,
the Drum turns past a Preclean Corotron.
This single wire Corotron neutralizes any charge on the Drum so that the Clean Brush and
scraper Blade can clean the Drum more easily. The rotating Brush cleans off the Drum and
carries toner residue away that the Blade scrapes off. A Flicker Bar cleans the toner particles
off the Brush and an auger moves this waste toner out of the Xerography module to the Waste
Toner Auger unit for transport to the Waste Toner Bottle.
