Composition/Operation
B. Main erase lamp/Y,M,C control
• The main erase lamp/Y, M, C radiation onto the PC drum surface neutralizes potential left
on the surface of the PC drum.
C. Cleaning/main erase operation
1.
After the image transfer process, the PC drum surface is irradiated by the main
erase lamp/K to remove potential left on the surface. (Only for IU/K)
2.
The cleaning blade is pressed up against the surface of the PC drum, scraping
residual toner off the surface (Blade abutting PC drum in a counter direction).
3.
Toner, which has been scraped off the surface of the PC drum, is conveyed to the
front side of the machine by the toner collecting screw. It is collected into the waste
toner collecting box.
4.
The PC drum surface is irradiated by the main eraser lamp/Y,M,C to remove (neu-
tralize) potentials left on the surface.
