4. USING PRINTER
4.1 Power-on Utilities
There are three power-on utilities to set up and test hardware. These utilities are
activated by pressing the FEED or PAUSE button and turning on the printer
power simultaneously. The utilities are listed as below:
1. Self-test
2. Gap sensor calibration
3. Printer initialization
4.1.1 Self Test Utility
Install the label first. Press the FEED button and then turn on the printer power.
Do not release the FEED button until the printer feeds labels. The printer
performs the following items:
1. Calibrate label pitch
2. Print out thermal print head check pattern
3. Print the internal settings
4. Enter dump mode
Regarding the self-test and dump mode, please refer to section 3.5 "Self Test"
and section 3.6 "Dump Mode" for more information.
4.1.2 Gap Sensor Calibration Utility
This utility is used to calibrate the sensitivity of gap sensor. Users may have to
calibrate the gap sensor for two reasons:
1. The media is being changed to a new type.
2. Initialize the printer.
Note: The ERR. LED may flash if gap sensor is not calibrated properly.
Please follow the steps below to calibrate gap sensor:
1. Turn off the printer power and install blank labels (without any logo or
character) on printer.
2. Hold down the PAUSE button then turn on printer power.
3. Release PAUSE button when the printer feeds labels. Do not turn off
printer power until the printer stops and two green LEDs light on.
Note: Black mark sensor has fixed sensitivity. It is no need to calibrate the
black mark sensor
