2.7 DRUM CLEANING AND TONER RECYCLING
2.7.1 DRUM CLEANING
The cleaning blade [A] removes any toner remaining on the drum after the image is
transferred to the paper. This model uses a counter blade system.
The cleaning blade scrapes off toner remaining on the drum. When toner builds up
in the cleaning unit, toner at the top of the pile is removed by the toner collection
coil [B].
To remove the toner and other particles that are accumulated at the edge of the
cleaning blade, the drum turns in reverse for about 5 mm at the end of every copy
job. This feature is controlled with SP 2-998.
In addition, cleaning is done in the middle of a job if 100 sheets have been made
since the previous cleaning. This feature is controlled with SP 2-211.
