• Scanning single page documents:
The Document guide is set according to the document size. When the document is set, the Doc-
ument sensor detects the presence/absence of document to be scanned. When the Document
sensor detects presence of document, the TX motor starts rotating. The TX motor drives the ADF
(Automatic Document Feed) roller and TX drive rollers. The document is pulled in by the ADF
roller and is fed by the TX drive rollers. When the Document position sensor detects the top edge
of the document, the machine returns to the standby status and waits.
By pressing the [COPY] key + (number of copies) + [START] key, the standby status is canceled
and the LEDs for scanning are turned ON. At the same time, the TX motor starts rotating and
feeds the document to the CIS unit. The document is read, line by line (in units of one scanning
line width). When the Document position sensor detects the bottom edge of the document; the
document is scanned for a certain value then the LEDs are turned OFF and scanning is com-
pleted. The document is fed out by the TX drive rollers.
If the Document position sensor does not detect the top edge of the document within the speci-
fied time after the Document sensor detects the presence of document, a document jam is indi-
cated.
