Sensors > Diagnostics
This executable menu provides a graphical printout showing the
relationship of the Paper Out Threshold and the Gap/Mark Threshold. The
profile printout assists you in setting the thresholds for difficult media. This
includes pre- printed labels, and labels with poor gap/media dynamic range.

Manual Calibrate is another method of improving the printer's media sensing
and is only used when Auto Calibrate has failed or the Gap/Mark Threshold
or Paper Out Threshold values derived from Auto Calibrate do not improve
the media sensors' gap or mark sensing capability.

Sensors > Diagnostics > Media Profile
When "Print Profile" is executed, the printer will
advance media and print the media profile along the
length of each label.
The printer will continue to print the profile until you
press the ↵ ENTER key.
Sensors > Diagnostics > Manual Calibrate
To initiate Manual Calibrate, press ↵ ENTER key when
"Manual Calibrate" displays. You will then be prompted
for the remaining steps.
Manual Calibrate is completed successfully when the
displayed Sensed Distance correctly matches that of
the installed media. When Gap is selected, the Sensed
Distance should match the length from the trailing
edge of one gap to the trailing edge of the next gap (or
one label + one gap). When Mark is selected, the
Sensed Distance should match the length from the
leading edge of one black mark to the leading edge of
the next black mark.
This process takes longer than Auto Calibrate, and the
end result is a change to the Gap/Mark Threshold,
Paper Out Threshold, and Sensed Distance values
that the printer will use. These value changes take
effect immediately within the current configuration
menu.
Manual Calibrate supports label lengths up to 24
inches.
