Auto Calibration
When auto calibrating, the printer is determining the label length and media/ribbon
sensor settings.
Auto calibration occurs when the printer is turned on and each time the printer
recovers from an error condition. (To clear an error, open and close the printhead
assembly and then press the PAUSE key.) The printer will begin to auto calibrate
when all errors have been cleared.
The results of the auto calibration are stored in the printer's memory and are retained
even if printer power is removed. These parameters remain in effect until the next
calibration is performed.
NOTE: The auto calibration process will not take place if the ZPL
command or front panel setting for “MEDIA POWER UP” or “HEAD
CLOSE” is set to either “feed” or “no motion.” In these cases, the
printer assumes the media is correctly positioned and starts printing
without auto calibrating.
