(1) Erase LED ON timing
• The erase LED is turned ON when the photo conductor starts rotating.
(2) Erase LED OFF timing
• The erase LED is turned OFF after the lapse of a predetermined period of time after the corona charge output has been shut down. (That
is, the erase lamp is turned OFF after all charge left on the surface of the photo conductor is neutralized.)
4.3.3 Photo conductor cleaning
• Part of the toner image that is not transferred is left on the surface of the photo conductor. The residual toner is scraped off by the cleaning
blade.
• Toner, which has been scraped off the surface of the photo conductor, is conveyed by the toner collecting screw toward to the front of the
machine. It is discharged in the waste toner box.

(1) Cleaning blade
• The cleaning blade is pressed up against the surface of the photo conductor at all times. No cleaning blade retraction mechanism is
provided.
• The cleaning blade scrapes residual toner off the surface of the photo conductor as the photo conductor is rotated.
(2) Toner conveyance/collection mechanism
• The toner collecting screw is rotated by the driving force transmitted from the photo conductor. (The toner collecting screw rotates in time
with the rotation of the photo conductor.)
• Rotation of the toner collecting screw conveys toner scraped off the surface of the photo conductor toward the front of the machine.
• The toner conveyed to the front of the machine is discharged via the toner collecting port into the waste toner box.
• The toner collecting port is provided with a shutter mechanism. Mounting the waste toner box pushes the shutter at the toner collecting
port, opening the toner collecting port. The shutter is closed by the waste toner box removal and prevents the toner spilling from the toner
collecting port.
