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 specified, regardless which method
has been used.

Paper Sensor

The Paper Sensor parameter is read-only. By pressing the Enter
key, the optional media low sensor is automatically adjusted.
The Low Diameter parameter specifies the diameter of the media
supply roll, where SYSVAR(46) switches from 0 to 1.
SYSVAR(46) = 0 means that there is still a sufficient supply of
media, whereas SYSVAR(46) = 1 initiates error 1084 "Paper
low". The diameter is expressed in millimeters (1 mm = 0.04 in.).
Default value is 0 (mm) and the maximum value is 200 (mm).

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 firmware 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).

Head Resistance

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