Toner Supply and Development
The toner tank (1) holds sufficient toner for the entire life of the AIO.
The agitator (2) moves toner to the toner supply roller (3).
The supply roller provides toner to the development roller (4).
The metering blade (5) controls the amount of toner on the development
roller.
The toner on the development roller develops the latent image on the drum
as it rotates past.
The high voltage power supply applies the following:
¾ -600V to the development roller
¾ -1550V to the charge rollers
¾ -110V to the supply roller
¾ -490V to the metering blade
The development components – drum, development roller, metering blade, and
supply roller – are in contact. (= no photoconductor gap nor doctor gap.)
Relative peripheral velocities: OPC 1, Development roller 1.2, Charge roller
more than 1.2
This AIO uses mono-component toner. Therefore, no toner density sensor or
image density sensor is required.
The toner is negatively charged.
