XPM 80™ Thermal Printer Family
Rigidity: It is important that the paper roll holder support the paper firmly and not
move. This is especially true in high-speed printing applications and in large diameter
paper roll applications. Many paper roll holders are made from metal too thin to
support the heavy paper rolls they are expected to handle. This results in twisting
and warpage while printing, which binds the paper and causes paper jams. Vibration
during printing may also cause undesired movement of the paper roll.
Shipment: Do not ship your product with a paper roll mounted in the paper roll
holder. The heavy weight of the paper roll can easily bend or otherwise damage the
paper roll holder, as witnessed numerous times.
6.5. Power Supply Specifications
Selection of a power supply for thermal printers depends upon the printer's application, what
percentage of the printout is black, frequency with which printouts are generated, and more.
In particular, thermal printers draw very high currents for very short time periods (usually
under one millisecond). The most important issue is not peak current, but the length of time
that the power supply is able to deliver instantaneous current over its rated maximum, and for
how long the print job prints high black percentages, thereby drawing high current. It is
important that the power supply's over-current system does not shut down the power supply
when these brief, high current surges occur.
With that said, we recommend the following power supply specifications for most applications.
Please see the "Technical Specifications" section near the end of this document for full
details.
DC Output Voltage: 24 volts ± 5%
DC Output Current (nominal): 4 amperes
Hold Up Time: 20 ms minimum
Current Limitations: 16 amperes minimum current limit

Operation
7.1. Loading Paper
The XPM 80™ is equipped with a Dual-Feed unit (DFU) which allows two different paper
sources to be used.
"closed"; see figure 3 for details.
Insert the paper, thermosensitive side up, into one of the paper inlet slots in the rear of the
DFU. It is generally easier to load the lower paper path first. When paper is inserted into one
of the DFU paper inlets, the DFU automatically advances this paper and loads it into the print
mechanism. You will hear the paper feed motor start to run as soon as the DFU paper
detection sensor is reached. Continue to feed the paper until the rollers grasps it and pulls it
forward into the printer.
Now load the second paper path in the same way. While the functionality of the paper
loading can vary widely depending upon the settings of the XPM 80™ Configuration Tool, the
last paper loaded is generally automatically loaded into the printer and used for printing. If
you prefer to use the first paper path loaded, simply press and release the Dual-Feed control
button next to the desired paper path, and the printer will automatically paper paths. (Please
note that these buttons can be disabled by the Configuration Tool for security purposes. If the
buttons seem to be ignored, check for this in the printer configuration.)
The XPM 80™ thermal printer family is designed to use paper with the thermosensitive side
on the outside of the paper roll. This is important as the printer is optimized to deal with
paper curl angling the paper end downward.
