HP Pro 4300 C9H70UT C9H70UT#ABA manual Stacker jam detection, Stacker feed jam

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” on page 345.

●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 specific 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” on page 258 and “Numerical printer messages” on page 274.

Stacker feed stationary jam

If the paper inlet sensor (PS1101) does not detect the trailing edge of the media within a specific 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” on page 258 and “Numerical printer messages” on page 274.

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 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” on page 258 and “Numerical printer messages” on page 274.

Note	This jam only occurs if the paper delivery sensor (PS1102) detects media at the start of the initial
	drive.
