Minolta EP1030 - Cleaning and Toner Hopper Systems

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 sepa-
ration have been completed.
The Cleaning Blade is moved back and forth to prevent the PC Drum from deterio-
rating and the Cleaning Blade from warping away from the surface of the PC Drum.
There is a Toner Antispill Mylar affixed to the imaging Unit. It prevents toner scraped
off the surface of the PC Drum from falling down onto the surface of the copy paper
or the paper path.
In addition, a Side Seal is affixed to both ends of the Imaging Unit on both sides of
the Cleaning Blade. They prevent toner from spilling from both ends of the Cleaning
Blade.

a TONER HOPPER
The Toner Hopper is integrated into the Imaging Unit. To replace an empty Toner
Bottle, the user first needs to swing the Toner Bottle Holder out 20° to the front. The
Holder pivots about the Toner Supply Port as it is swung out or in, which effectively
prevents toner from spilling when the Holder is swung out or in.

9-1. Toner Replenishing
Drive from Main Drive Motor M1 is transmitted via the Magnet Roller to the Bottle Drive
Gear in the gear box. There is a holder installed on the Bottle Drive Gear, coupling the
Toner Bottle to the Bottle Drive Gear. This ensures that the Bottle Drive Gear turns with
the Toner Bottle. When Toner Replenishing Solenoid SL1, fitted to the gear box, is ener-
gized, it turns the Toner Bottle one complete turn, The spiral groove cut in the Toner
Bottle effectively prevents toner from remaining in the bottle.
