Enabling/Disabling External Signal Output - SATO S8400 Operator's Manual

Section 3: Configuration and Operation
About the 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.
• When a head check error occurs during normal printing (barcodes, text and graph-
ics), press and hold down the FEED button for five seconds. At the next screen,
select NORMAL and then press and hold down the LINE and FEED buttons for five
seconds to cause printing to resume. If the head check error occurs again, set the
type of head check to BARCODE and see if printing can be resumed normally.
• Although restricting the head check type to BARCODE allows you to continue print-
ing, you should only do so in order to complete an urgent print job. Check the
printed labels 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.
