Solution
• Check if the printer is out of media or
transfer ribbon
• Check that the printhead lever is closed
and locked
• If the printhead is closed and locked, but
the problem persists, the headlift sensor
may be out of order. Check connection to
P34 on the main board. Check headlift
microswitch.
• Check if media is jammed/tangled up.
Clear the jam and reload. Clean parts that
may have been exposed to the media's
adhesive using isopropyl alcohol or a
cleaning card.
• Check the light path between the upper
and lower parts of the label gap sensor to
see if it is obstructed by dust, adhesive, or
stuck labels. Clean using isopropyl alcohol
or a cleaning card.
• Recalibrate the sensors by running a
testfeed.
• Check to see if a bad command was sent
to the printer via Fingerprint or direct
protocol
• Check the Fingerprint application or the
last issued instruction in Direct Protocol
