Principles of Operation
Charge Metal Blade (CM Blade): Spreads an even coating of toner on
the Magnet Roll, and gives the Roll a static–electric charge.
Cleaning Blade: Removes any residual toner left on the drum from the
last print cycle.
Drum Shutter: When the CRU is in place in the printer and the Front
Cover is closed, the Drum Shutter opens to expose the area of the drum
surface that comes into contact with the paper during a print cycle. When
the CRU is out of the printer or when the Front Cover is open, the drum
shutter closes to protect the drum surface from light shock and contami-
nation.
