Scope

This addendum contains information about the new Calibration features added to the Zebra A300 and Zebra T300 printers when upgraded with the 25.8.1 and 23.8.1 and later versions of firmware respectively.

CalibrationAuto-Calibration

The printer only auto-calibrates when using non-continuous media (a gap, notch, or black mark separates each label). During this process, the printer sets the sensor levels for, and determines the length of, the labels being used. (To calibrate the printer for media with pre-printed labels or pre-printed backing, see “Manual Calibration.”)

The first time the printer is turned ON, auto-calibration senses if continuous media is loaded. If this media is used, the label length must be set through the label preparation software being used.

NOTE: If continuous media is sensed, non-continuous media can not be used until you either (a) reset the factory defaults (see “Feed Key Troubleshooting Modes” in the "Operating the Sys- tem" section of the printer user's guide), or (b) refer to your label preparation software user’s manual.

To auto-calibrate:

1.Load the media according to the instructions in “Setting Up the Zebra Printer” in the printer user's guide.

2.Turn the printer power ON.

3.Some blank labels will feed, completing the auto-calibration process.

4.If the Fault LED (A300) or Power LED (T300) begins flashing, refer to the “Manual Calibration” process.

Remember:

nAuto-calibration is performed when the printer is turned ON and whenever an error condition is cleared.

nSingle flashing of the A300 Fault LED indicates a PRINTHEAD OPEN condition. Single flashing of the T300 Power LED indicates an Error condition.

nDouble flashing of the LED (A300 Fault LED - T300 Power LED) indicates a printer PAUSED mode. Press the FEED Button and the printer will auto-calibrate.
