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 24 VDC
applications. Please see the "Technical Specifications" section near the end of this document
for full details on the various voltages available.
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 eXtendo series of thermal printers automatically loads paper when it is inserted. First,
make sure that the printhead is in the "down" position by pulling the Printhead Position
Control to the outer position. Then insert the paper, thermosensitive side up, into the paper
slot in the rear. You will hear the paper feed motor start to run as soon as the paper detection
sensor is reached. Continue to feed the paper until the platen grasps it and pulls it into the
printer.
®
The eXtendo 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 eXtendo
do so, print an Information Report immediately when paper is loaded. This short report is
extremely helpful during setup and configuration of the eXtendo
detailed information, some of it encoded, concerning the printer itself and its features, the
firmware installed, the status of information in the flash memory, and the 20+ settings that
configure the printer itself.
One example of how this report can be used involves the serial version of the eXtendo
printer family. If you want to verify the current serial settings (baud rate, stop bits, parity, etc.),
simply remove and reinsert the paper. This information is printed as part of the Printer
Information report. Please note that many of the software tools supplied with the eXtendo
driver also allow this report to be printed without removing the paper. Simply click on the
"Print Info" button.

7.2. Printhead Position Control

The printhead position control (see Figures 2 and 3) is used to raise and lower the thermal
printhead. This control moves in and out of the side of the printer, and has two positions.
