Troubleshooting

Manual Calibration

980608-001 Rev. C GK420d™ User Guide 8/4/10

Manual Calibration

Manual calibration is recommended whenever you are using pre-printed media or if the printer

will not correctly auto calibrate.

Make sure media is loaded.

Turn on the printer power.

Press and hold the Feed button until the green status light flashes once, then twice and

then continuing until the flash groups reach the group of seven flashes. Release the Feed

button.

The printer will set the media sensor for the label backing being used. After it is done

making this adjustment, the roll will automatically feed until a label is positioned at the

printhead. A profile of the media sensor settings (similar to the example below) will print.

Upon completion, the printer will save the new settings in memory and the printer is ready

for normal operation.

Press the Feed button. One entire blank label will feed. If this does not happen, try

defaulting (refer to the four-flash sequence in “Feed Button Modes” later in this chapter)

and recalibrating the printer.

Note •

Performing a manual calibration disables the auto calibration function. To return to

auto calibration, default the printer (refer to the four-flash sequence in Feed Button Modes

on page 70 in this section).
