Sensors > Calibrate - Printronix T8000 Administrator's Manual

Selects which type of media sensing, Transmissive or Reflective, will be used
to detect a paper out condition. The printer automatically selects the type of
sensing based on the Gap/Mark sensing selected as shown in Table 2.

Sensors > Calibrate
You can run Auto Calibration from the Home screen, this section, or the Tools > Print Tests > Run Test
menu. Upon execution, the printer advances media the distance needed to accurately detect the label
length indicators, then stops at the Top-of-Form position, and momentarily displays the Sensed Distance if
successful. This process takes a few seconds to complete and results in changes to the values the printer
uses in the Sensors > Control subsection for Gap/Mark Threshold, Paper Out Threshold, and Sensed
Distance. These value changes take effect immediately within the current configuration menu.

Use reflective sensor for paper out sensing
Use transmissive sensor for paper out sensing
Transmissive
Whenever you select Transmissive, you must
position the upper media sensor directly over the
lower media sensor (see Positioning the Media
Sensors page 34).

No activities at power up.
Auto Calibrate is performed at power-up. Once the
Auto Calibrate is complete, the printer will momentarily
display the Sensed Distance determined by the Auto
Calibrate.
Assumes user has already calibrated media and used
gap/mark sensor. This moves the media to
Top-of-Form at power up if Sensors > Control >
Gap/Mark Sensor is not set to Disable.
Auto-Cal
If Media > Top of Form >Ticket Save Mode is set,
Auto-Cal and Seek TOF will not be performed.
