Details

Head Cold is a WARNING (not an error) and displays a printer condition typically related to the environment where it is being used. The warning is typically displayed at temperatures below 15 degrees C (59 F).  The printer is not at risk of permanent damage so it will keep printing. Since this is a thermal printer you may observe the print quality degrade with ambient temperatures below the warning value. The printer will warm as you print labels and typically you see the warning disappear and print quality improve.

Additional Information

There is a ZPL Command that allows you to set the Head Cold Warning indicator on or off.

Format ^MWa

where a = Y/N

Note: You will not be able to confirm the command has been enabled or disabled since it is not a displayed parameter on the LCD Display or on the Configuration label.
