Bias Brush

The lubricant bar [A] lubricates the bias brush [B]. The brush applies this to the

transfer belt surface. The bias brush is positively charged to attract residual toner

from the belt surface.

Bias Roller and Cleaning Blade

The bias roller [C] removes toner from the bias brush. The cleaning blade [D]

removes the residual toner off the bias roller.

Collecting Coil

The collecting coil [E] transports waste toner to the rear of the transfer belt cleaning

unit. The waste toner bottle [F] collects the toner through its opening shutter.

Waste Toner Bottle Sensors

The waste toner bottle switch [G] and the waste toner bottle sensor [H] are at the

back of the cleaning unit. The switch detects whether the toner bottle is installed

correctly.

The toner bottle sensor detects when the bottle is full, and a message is displayed

on the operation panel. After the message is displayed, 100 prints can be output

then the machine stops and printing is disabled.
