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.
6.6. 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.

24 volts ± 5%

Operation
7.1. Loading Paper
Before loading the printer, make sure that the printhead is in the “closed” position; see figure
4 for details.
Insert the paper, thermosensitive side up, between the paper guides. You will hear the platen
motor start to run as soon as the paper detection sensor is reached. Continue to feed the
paper until the printer platen grasps it and pulls it forward into the printer.
The XPM 200HR™ 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.
Please note that the XPM 200HR™ thermal printer family will, unless specifically configured
not to do so, print an Information Report immediately when paper is loaded. This short report
is extremely helpful during setup and configuration of the XPM 200HR™ printer. This report
contains detailed information concerning the printer itself and its features, the firmware
installed, the status of information in the flash memory, status of the A/D converter outputs,
and the many settings that configure the printer itself. For example, this report will show all
the current serial communication settings.
Please note that many of the software tools supplied with the XPM 200HR™ driver also allow
this report to be printed by simply clicking on the “Print Info” button.
