Figure 5-16 Envelope-feeder pickup-and-feed diagram
Envelope feeder jam detection
The envelope feeder uses the envelope multiple-feed sensor (PS902) along with sensors in the
printer to detect the presence of media and to determine whether the media is feeding correctly or is
jamming.
If a jam occurs in the envelope feeder, the error message 13.xx.yy appears on the control-panel
display. For more information see
Numerical printer messages.
Envelope feeder pickup delay jam
If the pick-up sensor (PS103) does not detect the leading edge of the envelope within a specified
period of time after the envelope is picked up, it attempts to pick up the media several times before
determining that a pickup jam has occurred.
If the pre-feed sensor inside of the printer (PS102) does not detect the leading edge of the envelope
within a specific amount of time after the re-pick operation stops, the microprocessor on the dc
controller PCA determines that a jam has occurred.
The transport process stops and a 13.xx.yy message appears on the control-panel display. For more
information about jam messages, see
Numerical printer messages.
Envelope feeder pickup stationary jam
If the envelope multiple-feed sensor (PS902) detects multiple envelopes after the pickup operation
begins, the transport process stops and a 13.xx.yy message appears on the control-panel display.
For more information about jam messages, see
Numerical printer messages.
