5.1.5 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 media 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 media.
Reconfigure head check setting or disable
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 the FEED button and see
if printing can be resumed normally. If printing resumes, the print head fault does not fall on the barcode area
for the current print job. As such, printing may be continued but with degraded print quality and readable
barcode.
If the head check error still occurs and the current print job has to be completed, the printing can be forced to
resume by holding down the LINE and FEED buttons for five seconds. Please read the Caution note below
before you proceed with this operation.
CAUTION:
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 media to make sure the output is usable in spite of the head error.
As soon as possible, stop using the print head to prevent further damage. If necessary, get the
print head replaced.
