ITB cleaning
The cleaning blade in the ITB cleaner scrapes the residual toner off the ITB surface. The drum motor
(M5) drives the residual toner feed screw. The screw feeds the residual toner to the residual toner feed
unit. The residual toner feed motor (M12) drives the residual toner feed screw. The residual toner feed
screw deposits the residual toner in the toner collection box. The DC control detects whether the toner
collection box is full, using the toner collection-box-full sensor, and then notifies the formatter.
