Print Defi nes

Head Resistance

The printhead resistance is measured automatically at startup (read-only
information).

Testprint

The test labels "Diamonds", "Chess", "Bar Codes #1", and "Bar Codes
#2" are used to check the printout quality and facilitate adjustment of
the printhead pressure, see Chapter 12. The test labels "Setup Info" and
"Hardware Info" list the printer's current setup and the installed elec-
tronic devices. Test label "Network Info" is only printed if the printer
has an optional EasyLAN interface board. If the information does not fi t
on one label, two or more labels will be printed. If the printer refuses to
print a test label, press the <i> key to fi nd out what is wrong, for example
"printhead lifted" or "out-of paper". See next page for examples of test
labels.

Print Speed

The print speed is variable between 100 and 200 mm/sec. for printers
fi tted with an 8 dots/mm (203.2 dpi) printhead and between 100 and
150 mm/sec. for printers with an optional 11.81 dots/mm (300 dpi)
printhead. Generally, the lower the speed, the better the printout qual-
ity. This is especially true when printing bar codes with the bars running
across the media path ("ladder style"), when printing on demanding face
materials, and when printing at low ambient temperatures. The default
setting is 100 mm/sec. (≈ 4 inches/sec.).

LTS (Label Taken Sensor)

The sensitivity of the LTS may need to be adjusted according to ambi-
ent light conditions and refl ective characteristics of the back side of the
media. The LTS setup options are only displayed if an optional label
taken sensor is installed in the printer.
LTS Adjust
Press <Enter>. A label is fed out. Remove the label and press <Enter>
again. A menu shows the sensitivity automatically selected by the fi rm-
ware and the range, in which the LTS will work. Press <Enter> again and
you will proceed to the LTS Test menu.
LTS Test
Press <Enter>. A label is fed out. Remove the label and a new label
should be fed out automatically. Repeat until you are sure the LTS works
properly. Then press <Enter> to stop and exit.
