XPM 80™ Thermal Printer Family
The output of this sensor is also available from the Query function.
XPM 80™ Emulation Command Set Reference D 690 004 for details on determining
the printhead position and the printhead temperature.

3.5.7. Cutter Sensors

The XPM 80™ uses a "pizza-cutter" style paper cutter. A cutting disk moves from
one side to the other to sever the paper from the roll against a stationary blade.
Sensors are located at the end of travel for this cutter so the controller can detect
where the cutter blade is and determine in which direction it should be moved to cut
the paper.

3.5.8. Paper Exit Sensor

A sensor on the exit side of the print mechanism detects when paper has passed
through the cutter assembly and reached the paper exit.

3.5.9. Paper Pre-End (Paper Low) Sensors

The XPM 80™ has inputs for four sensors indicating Paper Pre-End (Paper Low).
There is one set of sensors (one for the upper paper path and one for the lower) to
detect standard Paper Pre-End (PPE). Connected to appropriately selected sensors,
these will signal via a query through the interface when paper has become low
enough to activate this signal. These two inputs are analog sensor inputs that are
converted to digital signals via analog to digital (A/D) conversion. Therefore, it is
possible to read their analog values and use this information as a measure of sensor
obstruction.
The second set of sensors are also for Paper Pre-End, but are intended for use as
what are commonly called "weekend sensors" (PWE).
sensors detect when paper has reached some user-defined point where a paper
change will be required shortly, PWE sensors are usually set to signal whether there
is enough paper remaining to make it through the weekend without replenishing the
paper.
available on weekends may not be trained in paper replenishment. The PWE inputs
are direct digital inputs. Since no supply is provided to power an LED-style sensor,
these inputs are best used with a microswitch.
