6.1.2 Warning and Fault Messages
The printer displays messages when the possibility of a problem or an actual fault occurs.
Depending upon the displayed message, find the possible action or solution in the tables
below.
 Note: Warning and Fault Messages do not appear in Menu or Test Mode.
Warning Messages:
Displayed for about three seconds, Warning Messages assume a low priority and indicate a
pending change in printer configuration, or an operating condition that could lead to a fault.
Warning Messages
Displayed Message Description Action(s)
DOT FAILURE
The printer has detected
defective printhead
elements.
Replace the printhead if the print
quality becomes unacceptable.
GAP MODE
WARNING LOW BACKING
The printer measured
only a small difference
between the “empty” and
“gap” sensor readings.
Transparent backing or notched
media typically gives this
indication, and a slight delay may
occur for the “Out of Stock”
indication; no action is required.
GOODBYE
Power has been removed
and shutdown is in
progress.
The power switch was turned
OFF; a line fuse was blown; or,
the line voltage was lost.
HEAD NEEDS CLEANING
The scheduled printhead
cleaning distance has
been reached.
Press and hold the TEST Key or
select CLEAN HEAD NOW; see
Section 5.6.1.
HOST CHANGES PENDING
The host has pending
configuration changes
that require a “host reset
command.”
To save the changes send a host
reset command (in DPL), or
discard changes by performing a
soft reset; see Section 5.3.1.
