PWB-F Board

The PWB-F board is the high voltage supply circuit board. It converts the
development bias, OPC drum charge bias, and image transfer bias.
Do not touch VR1F and VR2F on the PWB-F board. These volumes are for factory
setting only.
O p t i c a l U n i t
The optical unit consists of the laser diode (semi-conductor laser), the scanner
motor, which drives the scanner mirror for laser scanning, and several other
mirrors and lenses. The laser beam generated by the laser diode is conducted to
the OPC drum surface by the scanner mirror, as well as several other mirrors and
lenses, to create a latent electro-photographic image on the drum.
