5.1.1 More about Head Check Function

The head check function detects the integrity of the heating elements in the thermal print head. However,
malfunctions cannot be detected instantaneously—a few printed labels may start showing printing defects
before the printer warns of a print head error.
After detection of a print head error, use a scanner to check all affected labels.
Disabling the head check function
temporarily until the printer is turned off.
When a head check error occurs during normal printing (barcodes, text and graphics), press and hold down
the FEED button for five seconds. At the next screen, select BARCODE, then press FEED button and see if
printing can be resumed normally. If printing resume, the fault on the print head does not fall on the barcode
area for the current print job. As such, printing may continue but with degraded print quality and readable
barcode.
If the head check error still occurs and the current print job has to be complete, the printing can be forced to
resume by holding down the LINE and FEED buttons for five seconds. Please read the Attention below before
you proceed this operation.
ATTENTION:
Although restricting the head check type to BARCODE allows you to continue printing, or
forcing the printer to resume printing, you should only do so in order to complete an urgent
print job. Check the printed labels to make sure the output is usable despite the head error. As
soon as possible, stop using the print head to prevent further damage. If necessary, get the
print head replaced.
