L
The machine determines the relationship
between the amount of toner on the
transfer belt and the laser power for each
of the 10 grades. The machine now
selects the laser power to get the target
M/A.
After that, the machine cleans the
transfer belt by applying a positive dc
charge to the cleaning roller for three
rotations of the belt. It does not use the
cleaning blade.
