FAQ# 2134: How do I manually Calibrate my GK420 Zebra Printer?
How do I manually Calibrate my GK420 Zebra Printer?
There are two manual calibration types that can be performed.
2 Flash Feed: Standard Auto Media Calibration
Press and hold the Feed button while the printer is on. During this it will flash a number of times. Allowing it to flash twice and then releasing will perform a standard media calibration and set the media type and length.
7 Flash Feed: Manual Media Calibration
Similar to the standard auto calibration, you would hold down the feed button and then allow it to flash seven times before releasing. This will set the printer to run an extensive test that will detect and set the media type and length, as well as adjusting the media sensors for best performance.
