Functional Overview
Image Formation System
Cleaning Stage
During the cleaning stage of the image formation process, the
drum’s surface is physically cleaned, preparing it to hold an image.
During printing, the drum is rotating constantly making several
complete rotations per printed page. Before forming the image for
a given section of print, a cleaning blade removes toner from the
previous rotation of the drum. The excess toner is stored in the
toner cartridge where it is prevented from being used in later print
jobs (see Figure 5-11).
