Developer Drive - Lexmark CX825 Service Manual

Developer drive

A shutter for each developer unit receives toner from the toner cartridge. Inside the developer unit, the toner
is circulated by rotating augers so that it is evenly distributed. The developer roller also rotates to apply the
toner particles to the photoconductor drum.
The C, M, and Y developer rollers and augers are driven by a motor. The K developer roller and augers are
driven by a separate motor.
