Calibrate RFID Tag
This parameter sets the RFID programming position through a tag
calibration, or it restores the programming position back to the printer
default.
RESTORE Selecting this option resets the RFID programming position
to the printer default.
Note • With some printers and firmware versions, no label
movement or changes to the control panel occur. With others, the
printer displays PROGRAM POSITION RESTORED.
• For the R110PAX4, the RFID programming position is zero (the
printer programs the tag without moving the label). By default, the
print engine has backfeed set to After, which places the transponder in
the optimal place for encoding for Zebra-specified media. If you are
using a backfeed setting other than After, do not use the RESTORE
function unless the position of the transponder in your media accounts
for this change.
• For other RFID printers, the RFID programming position is the label
length minus 1 mm (0.04 in.).
RUN If the media being used does not conform to transponder placement
requirements for your printer, use the
RUN option to have the printer
determine the optimum programming position for the non-standard labels.
Important • Do not perform transponder calibration for RFID
media that meets the transponder placement specifications for your
printer. RFID tag calibration is necessary only if the transponder is
not in the ideal location for programming at the printer’s default
position.
The printer feeds an RFID label one millimeter at a time while taking
readings (via the READ TAG command and the WRITE TAG commands)
to profile the RFID transponder. Based on the results, the printer
determines the optimum programming position for the media and saves the
position to nonvolatile memory (the value is saved even if the power is
turned off). The calibrated value is used as the programming position for
the
^RS command unless the command specifies a different value.
Tag calibration takes into account the print mode, backfeed mode, and tear
off position. The
^HR ZPL command performs the same calibration and
returns a results table to the host (see ^HL or ~HL on page 84). An auto-
calibration occurs after the tag calibration. This realigns the media to its
proper rest position and updates the media tracking values in the printer.
To restore the programming position to the default:
1. Press the left oval/MINUS (-) to select RESTORE.
To calibrate an RFID tag:
1. Load the printer with RFID media.
2. Close the printhead.
3. Press the right oval/
PLUS (+) to select RUN.
