Theory of Operation
Preregistration
In the preregistration process, the media (fed to the Takeaway Roller in the
prefeed process) is fed to the Registration Roller. The lead edge of the media
is then fed from the Registration Roller to the scan feed reference position
(Wait Position), located upstream from the CVT position, where the media
stops. This operation accomplishes registration of the lead edge of the media.
The ADF Motor drives the Takeaway Roller when the media is fed to the
Takeaway Roller, which then feeds the media to the Registration Roller. When
the Registration Sensor detects the media, the ADF Motor rotates to drive the
Registration Roller and Exit Roller. The Registration Roller feeds the media
(fed from the Takeaway Roller) to the scan feed reference position.
Scan Control
Scanning of the image illuminated with the Exposure Lamp of the Scanner
Assembly is controlled by changing the feed speed according to the copy
magnification.
When the media passes the CVT position at the specified speed, the images
on the media are exposed by scanning with the Exposure Lamp of the
Scanner Assembly, and read by the CCD Image Sensor.
