(9)Cleaning

Cleaning is the process of removing the re- sidual toner from the photoconductive drum.

The edge of the urethane rubber cleaning blade is pressed against the photoconductive drum surface to scrape off the residual toner on it. The toner is then caught by the recovery blade.

(10)Discharging

Discharging is the process of eliminating the negative charge remaining on the photocon- ductive drum before the next charging pro- cess.

If the residual charge is not eliminated, the fol- lowing phenomenon occurs:

The negative charge remains on the photo conductive drum.

Uneven charge is applied to the drum during the next printing.

The next print will have a double image. (The preceding image appears.)

Solution :

The entire surface of the photoconductive drum is illuminated with light by the discharge LED array.

The photoconductive drum becomes electri- cally conductive.

All of the negative charge remaining on the photoconductive drum is conducted to the ground.

Preparation for the next printing is completed.
