Jam detection
When the sensors inside the ADF detect a jam, the feed and read motors immediately stop. A signal is sent to the scanner controller board, which notifies the formatter. An error message appears on the
To clear a jam, open the
Residual-media jam
During the initialization sequence or after the ADF jam cover has been opened and closed, if the registration sensor, read sensor, or exit sensor detects the presence of media, the scanner controller board determines that a
ADF pickup jam
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 jam
ADF jams can occur in three places inside the ADF.
Registration-sensor jam
If the registration sensor does not detect the trailing edge of the media after the leading edge reaches the
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
Read-sensor jam
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
Exit-sensor jam
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

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