Normal scanner operation
At power up or after a Control Panel reset, the scan motor rotates to verify it is ready
for operation. Scan functionality is only available through PC software. A scan can be
initiated two ways: from the PC or from the scanner Control Panel.
When the scan key is pressed on the scanner, it sends a signal to the PC to let it know
the firmware is ready to scan. The PC will either prompt the user to start the scan from
the PC, or automatically start it, depending on how the Document Assistant is
configured. When a scan job is initiated the scanner will pick up a page from the
automatic document feeder (ADF), and then wait for the necessary resources to be
acquired.
The copy key functionality is always available, even when the printer is disconnected
from the PC. When the copy key is pressed it starts the scan of the document from the
ADF. If the scanner cannot get the resources it needs, it still picks the first page from
the ADF to give the user feedback. When the resources needed to continue are
acquired, the scan is started. This scan is passed directly to the printer as print data
and printed. This is called a Quick Copy. As much as .75 inches may be clipped
(discarded) depending on available memory. If memory resources are limited or the
copy original exceeds the printer media by more than .75 inches, the remaining copy
data will be printed to a second page with no data lost.
At any time during a scan or Quick Copy the user can press both the scan and copy
keys to abort the scan. If there is still a sheet inside the scanner it will enter the jam
mode and the sheet will have to be removed manually. If a Quick Copy occurs the
printer will still print any data it has received
