Developing Roller Drive - Printronix L5000 Series Maintenance Manual

Developing Roller Drive

The developing roller consists of the inner-pole magnet and sleeve. The inner-pole
magnet is driven by the magroll motor, whereas the sleeve is driven by the sleeve
motor. The magroll motor also drives the agitation roller via the inner-pole magnet.
The toner supply clutch is activated to drive the toner supply roller as well as the
inner-pole magnet and agitation roller when the toner density sensor detects a low
toner density, or when the controller asserts an engine operation request command for
toner supply.
