ADF Jam Detection
The ADF has two sensors that detect paper. The paper present
sensor detects the presence of media in the ADF input tray. The form
sensor detects media moving through the ADF. If a jam is detected,
the ADF immediately stops the paper feeding and the control panel
displays a jam message.
A jam can be detected under any of the following conditions:
 Document feeder jam—When documents are detected as
present in the ADF input tray, and a command to copy, scan or
fax is received, the scan module travels to the left side of the
scan assembly and stops beneath the ADF scanner glass. The
ADF then attempts three times, or for about ten seconds, to
advance the paper to the form sensor. If the paper does not
advance, the scan module travels back to the home position on
the right side of the scanner assembly. The control panel displays
the message Doc. Feed Mispick. Reload.
 Long document jam—If the paper has advanced to trigger the
form sensor, but the trailing edge is not detected within the time
allowed for a 15 in document (the maximum allowable page
length for the ADF), the scanner returns to the home position at
the right side of the scanner assembly. The control panel displays
the message Doc. Feed Jam.
 Stall jam—When a page that is less than 15 in long has
advanced to the form sensor but has not left it within the expected
time, the paper has probably stalled or jammed. The scanner
returns to the home position at the right side of the scanner
assembly. The control panel displays the message Doc. Feed
Jam.
 Other—If the paper stops in the ADF and the scan module
remains under the ADF scanner glass, an internal firmware error
has probably occurred. This is usually remedied by cycling the
power.
