Manual Calibration
A manual calibration should be performed whenever you are using
pre-printed labels (or label backing) or if the printer will not correctly auto
calibrate.
1. Turn on the printer power.
2. Remove approximately 6” (152 mm) of labels from a section of
backing material. Load the media so that only the backing material is
threaded through the printer and under the printhead.
3. Use the Media Tracking (^MN) command to select the appropriate
media type (refer to the ZPL II Programming Guide).
4. Press and hold the feed button until the green status LED flashes once,
then twice. Release the feed button.
5. The printer will set the media sensor for the label backing being used.
After it is done making this adjustment, the roll will automatically feed
until a label is positioned at the printhead.
6. A profile of the media sensor settings (similar to the example in
Figure 32) will print. Upon completion, the printer will save the new
settings in memory and the printer is ready for normal operation.
7. Press the feed button. One entire blank label should feed. If this does
not happen, try defaulting (refer to the four-flash sequence in “Feed
Button Modes” on page 37) and recalibrating the printer.
NOTE: Performing a manual calibration disables the auto
calibration function. To return to auto calibration, default the
printer (see the four-flash sequence in
“Feed Button Modes” on
page 37).
