2-1-6 Cleaning and charge erasing sections
The cleaning section consists of the cleaning blade that removes residual toner from the drum surface after the transfer
process, and the cleaning spiral that carries the residual toner back to the waste toner tank.
The cleaning lamp (CL) consists of LEDs and removes residual charge on the drum before main charging.
Also the toner quantity in the waste toner tank is sensed with the overflow sensor (OFS).
