XF
eXtendo®
Thermal Printer Family
5 Operation
5.1 Loading Paper - Autoload
The eXtendo® XF series of thermal printers automatically loads paper when
it is inserted. First, make sure that the printhead is in the "down" position
by pushing the Printhead (3a) down until it snaps into place on both sides
of the chassis. Then insert the paper, thermosensitive side up, into the
paper entry area (2) in the rear. You will hear the 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.
Please note that the eXtendo® XF thermal printer family will, unless
specifically configured not to do so, will print a configuration and
diagnostic report immediately after paper has loaded. An example of such
an "Info Printout" is shown on the right. This short report is extremely
helpful during setup and configuration of the eXtendo® XF printer. It
contains detailed information about the printer itself, date of manufacture,
feature sets, firmware version, flash memory contents, and other data
representing your printer's configuration setup.
One example of how this report can be used involves the serial baud rate
settings of the printer. If you want to verify the current serial settings (baud
rate, stop bits, parity, etc.), simply remove and reload the paper. RS232
settings are printed as part of the Info Printout. Please note that many of
the software tools supplied with the eXtendo® XF driver also allow this
report to be printed by command without removing the paper. Simply
click on the "Print Info" button.
HINT: In case the automatic Info Printout is disabled on your printer, you
can generate a report when you unlock and lock the printhead (3a → Fig.
2) three times.
The eXtendo® XF 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.
5.2 Printhead Lock
The printhead locking shaft (3a) is used to unlock and raise the printhead holder with the thermal
print head. This allows easy access of paper path and print head in case of paper jam conditions or
cleaning or other investigation. For the printer to be ready for printing or paper loading, both ends
of the locking shaft must reside in their latched down position.
Leaving the printhead in contact with the platen for a long period of time without paper under the
printhead may rarely cause a temporary indentation in the platen, which can result in initial feeding
difficulties when loading paper (sometimes called "rattle snake noise"). If this occurs, simply open
and close the Printhead and re-load paper or just turn the blue paper advance wheel (7) by hand to
overcome the indentation.
5.3 Paper Advance Wheel
The eXtendo® XF family of printers is equipped with a Paper Advance Wheel to make it simple to
manually advance paper when needed (→ Fig. 5). Rotating this wheel counterclockwise (the
direction labeled "Paper In" on the wheel) will draw paper in from the paper supply at the rear of
