Theory of Operation
Prefeed
In the Prefeed process, media is fed from the Feed Roller to the Takeaway Roller.
When the Nudger Roller is pressed down to the media surface, the ADF Motor
rotates to drive the Nudger and Feed Rollers. The Nudger Roller feeds the top
media in the document tray to the Feed Roller. The Feed Roller, nipped by the ADF
Separator Pad, feeds the media. When the Feed Sensor detects the media, the
printer recognizes that first media feeding is complete.
ADF Scan Control
Scanning 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.
Simplex Document
For simplex document, media feed is performed as follows:
1. The media is fed to the Takeaway Roller and then fed to the scan feed
reference position.
2. The media is fed at the speed corresponding to the selected magnification,
and the image on it is scanned with the Exposure Lamp at the CVT position.
3. As the image is scanned, media is fed and ejected by the Exit Roller that is
driven by the ADF Motor.
