6.3.1 OVERVIEW
Exposure
The exposure lamp [A] exposes the original. The reflected light is passed to the CCD, where
it is converted into analog data, processed, and stored in the memory. The data is retrieved
and sent to the laser diode for printing
Drum charge
The charge roller [B] gives a negative charge to the organic photoconductive (OPC) drum.
The charge remains on the surface of the drum because the OPC layer has a high electrical
resistance in the dark.
Laser exposure
Processed data from the scanned original is retrieved from the memory and transferred to
SM 6-9 D009/D011/D012/D013
