Zebra GK420t Setup Instructions

Troubleshooting
Problem: The printer starts printing at the wrong part of the hangtag
Solution #1: Verify that there is no tear offset configured within “Zebra Setup Utilities”, verify that the
physical media has the stop bar in the correct place, if not adjust the tear offset accordingly.
Solution #2: Run the “calibrate media command”. To do this, open “Zebra Setup Utilities”, select the
correct printer, click “Open Printer Tools”, click the “Action” tab, select “Calibrate media” and click
“send”. The printer will print a series of blank hangtags and use its “eye” to locate the stop bar. When
the process is finished, the printer paper feed light may blink, if it does press the paper feed button
once.
