Chapter 6—Setting Up the Printer
Contrast
Use the contrast parameter to make minor adjustments of the blackness
in the printout, for example to adapt the printer to variations in quality
between different batches of the same media. 11 options are displayed in
an endless loop from -10% to +10%. Default value is 0%. The contrast
is reset to the default (±0) whenever a new paper type is specifi ed, regard-
less which method has been used.
Testfeed
The sensitivity of the label stop sensor (LSS) may need to be adjusted
when switching from one type of media to another. This is especially
the case when using adhesive labels since the transparency of the liner
(backing paper) may vary. When the Testfeed menu is displayed, press
the <Enter> key. A number of blank copies will be fed out until the
fi rmware has decided the proper setting for the LSS. At the same time,
the front edges of the labels, tickets, etc. are detected so the feed control
can position the media according to the Feedadjust parameter (same as
the Intermec Fingerprint statement TESTFEED). Four values used for
troubleshooting the LSS are displayed (read-only information).
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.
