Operating Principles Printing Process 82
2.2.3 Exposure Process
The printer creates the latent image on the photoconductor by the laser beam
emitted from the print head. Printing position is adjusted as described below.
†
Main Scanning Printing (Horizontal)
„
By SOS sensor on the laser diode control board (PWB-C), the main
scanning printing start position is determined.
†
Sub Scanning Printing (Vertical)
„
When it receives PRINT signal from the controller, the engine control
board (PWB-A) rotates the polygon motor (M6) and transfer motor.
„
When transfer belt position sensor becomes ON, the print head
receives video signal from the controller and adjust the sub scanning
printing start position by emitting the laser beam and starts exposure.

No. Name Explanation
1 Photoconductor
Creates the latent image by laser beam on the surface of
the OPC drum (photoconductor), develops the image by
toner, and transfers the image on the transfer belt.
2 Cleaner Blade Cleans the remaining toner on the photoconductor.
3 Electric Charger
Scotron method charger gives (-) electricity on the
photoconductor.
4 Rotation coil
This coil carries waste toner, generated from the
photoconductor, to the waste toner bottle.
5 Grid Electrode
Steadily provides electricity, generated by electric
discharge, to the photoconductor.
