Drum cleaning (Sub step 1)

The toner remains slightly on the drum after the first transfer. The process that cleans the remaining toner off is
called "drum cleaning."
The cleaning is made by the cleaning blade provided for each drum. Its edge made of urethane rubber scrapes
the toner off the drum surface.

Exposure before charging (Sub step 2)

After the drum cleaning, electric potential slightly remains on the drum surface while the toner is completely
removed.
Since charging the drum for the next copying or printing cannot be normally performed with the remaining
potential, the potential on the drum surface is completely neutralized by means of erase lamp (EL). This process
is called "Exposure before charging."
