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, regardless 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. Adjusting the LSS entails feeding
out a number of blank copies 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). The comparator and amplifi er
values of the LSS are displayed (read-only information).
Head Resistance
The printhead resistance is measured automatically at startup
(read-only information).
Testprint
Test label #1 to #4 check the printout quality and facilitate adjustment
of the printhead pressure, see Chapter 13, "Adjustments." Test label
#5 lists the printer's current setup (extra labels may be printed if the
printer is fi tted an optional interface board). Test label #6 is only
printed if the printer has an optional EasyLAN 100i interface board.
Test labels #1 to #5 are illustrated on the next page. If the printer
refuses to print a test label, press the <F3> key to fi nd out what is
wrong, for example printhead lifted or out-of paper.
