Print Engine Operation
Calibrate the Print Engine
Calibrate the Print Engine
Calibrate the print engine when it is first put into service. Calibration allows the print engine to
establish the proper settings for the specific media and ribbon used in your application. You
may calibrate the print engine at other times as needed. Table 4 shows the different methods
for calibration.
Table 4 • Types of Calibration
Type of Calibration Description When/How It Occurs
Auto-calibration The print engine automatically sets
the value it detects for the spaces
between labels.
Occurs at the following times:
• When the print engine is first
turned on if CALIBRATION is
selected for
MEDIA POWER UP
(see Select Media Power-Up
Option on page 69)
• When the print engine feeds media
after the printhead is closed if
CALIBRATION is selected for
HEAD CLOSE (see Select Head
Close Option on page 69).
• As part of both the sensor profile
and media and ribbon sensor
calibration procedures.
Long (Standard)
Calibration
The print engine does the following:
• feeds media and ribbon
• sets the values it detects for media
length, media type (continuous or
non-continuous), and print mode
(thermal transfer or direct thermal)
• updates the sensor values
To perform a long calibration, do one
of the following:
• Press
PAUSE on the front panel to
pause the print engine, and then
press
CALIBRATE.
• Select CALIBRATION for the
MEDIA POWER UP or HEAD
CLOSE parameter (see Select
Media Power-Up Option
on page 69 or Select Head Close
Option on page 69).
Short Calibration The print engine calibrates using the
current sensor values rather than
detecting the spaces between labels
and resetting the sensors. This
calibration sequence uses fewer
labels than the long calibration
sequence, but it is less reliable
because the values that are stored in
the sensors could be incorrect.
Select SHORT CAL for the
MEDIA
POWER UP or HEAD CLOSE
parameter (see Select Media
Power-Up Option on page 69 or
Select Head Close Option
on page 69).
