High Capacity Output Expander Theory - Lexmark MS81 Series Service Manual

The main motor drives the transport rollers which move the media along the paper path. The sensor (pass through)
detects if the media has entered the expander. The diverter of the expander controls which way the media will go. If
the diverter is closed, then the media will exit into the output bin. If the diverter is opened, then media will pass through
the output expander and enter the output option above it.
Upon exit, the media is fed out by the exit rollers towards the output bin. The sensor (bin full) verifies if the media has
exited. The media level on the output bin is detected by the actuator flag. When the output bin is full, the actuator flag
triggers the sensor (bin full). A signal will be sent to the printer:
•
to prompt the user to clear the output bin
•
to change the direction of the paper path, re‑routing the media to the next output bin or output option above it

High capacity output expander theory

The function of the HCOE, which is to allow extra capacity to a printer's output bin, is similar to the output expander.

the position of its output bin to accommodate more media.
HCOE paper path
When the HCOE is installed on top of the printer, the diverter plunger changes the position of the diverter below it.
Since the diverter position of the printer below is opened, the printed paper will be re-routed. Instead of exiting the
standard output bin, the media enters the HCOE. The movement of the diverter plunger can be controlled by its diverter
motor, depending on the printer's commands.
Note: The diverter motor controls the diverter below it. Another way of saying it is that the diverter is controlled by
the diverter motor of the output option above it.
The main motor drives the transport rollers which move the media along the paper path. The sensor (pass through)
detects if the media has entered the HCOE. The diverter of the HCOE controls which way the media will go. If the diverter
is closed, then the media will exit into the output bin. If the diverter is opened, then media will pass through the HCOE
and enter the output option above it.
