August, 2006 TONER SUPPLY

Detailed
Descriptions
6.9.2 TONER SUPPLY MECHANISM
The toner pump [A] pulls toner into the sub hopper [B] from the toner cartridge [C],
through the flexible tube [D]. The toner hopper motor controls the mechanism,
through the toner pump clutch [E].
Toner cartridge Æ sub hopper
The toner pump supplies toner to the sub hopper. If the toner end sensor [K] output
detects "No Toner", the toner pump switches on for 2 seconds, and pumps toner
from the toner cartridge to the sub hopper.
Sub hopper Æ development unit
Based on the toner coverage of the previous print (detected by the TD sensor) the
machine determines how much toner was consumed, compares it with the amount
remaining, and then switches on the toner supply clutch for the correct time to
increase the amount of toner in the development unit.
The toner supply augers [F] move toner from the hopper [G] into the development
unit [H]. The toner hopper motor [I] controls the mechanism through the toner
supply clutch [J].
