If the leading edge of the media did not reach the registration sensor within a specific period of time,
the scanner controller board determines that an ADF pickup jam has occurred.

ADF jams can occur in three places inside the ADF.

If the registration sensor does not detect the trailing edge of the media after the leading edge
reaches the scan-ready position, the scanner-controller board determines that an ADF jam has
occurred.

Also, when the scanner duplexer is in use, if the registration sensor does not detect the leading edge
of the media after a specific period of time after media enters the duplexer, the scanner-controller
board determines that an ADF jam has occurred.

If the read sensor does not detect the leading edge of the media within a specific period of time, or if
the read sensor does not detect the trailing edge of the media within a specific period of time after it
detects the leading edge, the scanner-controller board determines that an ADF jam has occurred.

If the exit sensor does not detect the leading edge of the media within a specific period of time after
the leading edge reaches the read sensor, or if the exit sensor does not detect the trailing edge of
the media within a specific period of time after the read sensor detects the trailing edge, the scanner-
controller board determines that an ADF jam has occurred.

If the ADF jam-access cover is opened while media is feeding through the ADF, a jam occurs.

If the ADF is opened while media is feeding through the ADF, a jam occurs.
