CLEANING UNIT
18-1. Construction of the Cleaning Unit
•
The Cleaning Blade is pressed tightly against the surface of the PC Drum
and scrapes off any toner remaining on the surface after image transfer
and paper separation have been completed. The scraped-off toner falls into
the Toner Conveying Coil and is conveyed by that Coil to the Toner Chute
into the Toner Collecting Bottle at the back of the copier.
•
The Blade Tension Spring ensures that the Cleaning Blade is pressed
against the PC Drum surface at a given constant pressure.
•
The Toner Antispill Mylar prevents the scraped-off toner from falling onto
the areas inside the copier, ensuring all scraped-off toner falls on the Toner
Conveying Coil.
•
The back surface of the Cleaning Blade has the toner applied when setting
up the copier and that accumulated during a number of copy cycles. This
toner can stick again to the areas on the surface of the PC Drum where
there remains surface potential, adversely affecting the copy image. This
copier is equipped with Pre-Cleaning Erase Lamp LA5 located immediately
under the Cleaning Unit. Light from LA5 striking the surface of the PC
Drum reduces surface potential, thereby preventing toner accumulated on
the back side of the Cleaning Blade from sticking to the surface of the PC
Drum.
•
The PC Drum Paper Separator Fingers join forces with the Paper
Separator Corona to positively separate the paper from the surface of the
PC Drum.
