time or that media is not present at the expected time. The microprocessor on the MBM-driver PCA
notifies the formatter that a jam has occurred.
When a jam is detected, the transport process stops and a 13.XX.YY JAM message appears on the
control-panel display.
Feed-delay jam
If the inlet sensor (PS1501) does not detect the leading edge of the media within a specific time
period after receiving a delivery-notice command, the microprocessor on the MBM-driver PCA
determines that a feed-delay jam has occurred. The time interval is longer for face-up delivery than
for face-down delivery.
Feed-stationary jam
If the inlet sensor (PS1501) does not detect the trailing edge of the media within a specific time
period after it detects the leading edge, the microprocessor on the MBM-driver PCA determines that
a feed-stationary jam has occurred.
Residual-media jam
If the inlet sensor (PS1501) detects the presence of media during the initial WAIT period, the
microprocessor on the MBM-driver PCA determines that a residual-media jam has occurred.
Power-on sequence
The following figure illustrates the operational sequence of the MBM from power-on to standby.
