Stacker jam detection
The stacker uses the following sensors to detect the presence of media and to verify whether the
media is feeding correctly or is jamming. For information about the location of these sensors, see
Stacker and stapler/stacker switches and sensors.
■ Paper-inlet sensor (PS1101)
■ Paper-delivery sensor (PS102)
Stacker-feed jam
If the paper-inlet sensor (PS1101) does not detect the leading edge of the media within a specified
period of time after the stacker driver has received the paper-delivery signal, the dc controller PCA
determines that a stacker-feed delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages and Numerical printer
messages.
Stacker-feed stationary jam
If the paper-inlet sensor (PS1101) does not detect the trailing edge of the media within a specified
period of time after the paper-inlet sensor (PS1101) detected the leading edge of the media, the dc
controller PCA determines that a stacker feed-delay jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages and Numerical printer
messages.
Stacker residual-media jam
If the paper-inlet sensor (PS1101) or the paper delivery sensor (PS1102) detects media during the
initial drive period, the dc controller PCA determines that a stacker residual-media jam has occurred.
The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
For more information about jam messages, see
Alphabetical printer messages and Numerical printer
messages.
NOTE This jam message only appears if the paper-delivery sensor (PS1102) detects media
at the start of the initial drive.
