Slit Glass Cleaning Mechanism - Toshiba e-STUDIO 5540C Service Manual

3.10.3

Slit glass cleaning mechanism

The laser optical unit has a protective shutter on its upper section. This shutter is opened or closed with
the drive from the shutter motor (M38). Two shutter sensors (for home position, S24 and for end
position, S25) detect the phase of the shutter when it is opened or closed. When the shutter is closed,
the shutter sensor (home position, S24) is ON.
A cleaning brush installed inside of the shutter cleans the slit glass when the shutter is opened or
closed. The shutter performs cleaning by opening or closing itself every time the power is turned ON,
printing starts, printing ends or image quality control is performed.
