Running Auto Calibrate - Printronix t8000 Administrator's Manual

Auto or Manual Calibrate is completed successfully when the displayed Sensed Distance value 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.
When you have completed Auto or Manual Calibrate, you can verify the new values are correct by
pressing the FEED key several times. Each time you press FEED, media advances one label and stops at
the correct Top-of-Form position of the next label.
Once you confirm the correct values, save them to the desired configuration menu before powering off the
printer. See Saving a Configuration page 54.

Running Auto Calibrate

You can initiate Auto Calibrate via the Home Screen ICON
Settings section.
NOTE:
Verify that the Gap/Mark Sensor option (Gap, Mark, Advanced Gap, Advanced Notch, or
Disable) matches the installed media. See Sensing Different Media Types page 40.
Check that the media sensors are horizontally positioned to permit sensing of the label length
indicators. See Positioning the Media Sensors page 35.
Make sure the Media > Image > Label Length value matches the physical length of the installed
media. Entering the correct length forces the printer to advance media far enough during
calibrate for long labels (so actual gaps, notches, and marks can be detected) and reduce the
amount of media advanced for short labels.
If you try to do an Auto Calibrate
display "CANNOT CALIBRATE" error. Before you can do an Auto Calibrate, you must select
another media handling mode.
1. Press the PAUSE key to place the printer OFFLINE (Home Screen).
2. Select the Calibrate
3. Media advances until it can accurately detect the label length indicators and then stops at the
Top-of-Form position. The Sensed Distance value will then display for one second.
4. Auto Calibrate is successful when the Sensed Distance value correctly matches that of the installed
media:
•
Gap/Mark Sensor = Gap, Advanced Gap, or Advanced Notch: The Sensed Distance value
is the physical length of one label plus the length of one gap, notch, or hole.
•
Gap/Mark Sensor = Mark: The Sensed Distance value is the physical distance from the
leading edge of one black mark to the leading edge of the next.
•
Gap/Mark Sensor = Disable: Not applicable. If Gap/Mark Sensor is set to Disable, the Sensed
Distance value will not be updated.
If "GAP NOT DETECTED" displays, run Auto Calibrate again.
If Auto Calibrate continues to end with an incorrect Sensed Distance value displayed or a fault
message displayed, run Running Manual Calibrate as described on page 46 or see Table 13 on
page 258.
NOTE:
The amount of media sampled during Auto Calibrate is based on the length of a label and
transitions detected, without error, between a label and its label length indicators.
5. Press the FEED key several times. Each time you press FEED, the media advances one label length
and stops.
