Drum Cleaning and Toner Recycling
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.
