POWER FAILURES
Printer fails to turn on, the
display is not backlit. 1. Check that the printer AC power cord is correctly attached
to the printer and to the AC power outlet.
2. Have a qualified electrician test the AC wall outlet for the
correct power range. Locate the printer in an area that has
the correct power range.
3. Check the AC power cord. Replace a damaged AC power
cord or one that you suspect may be bad.
4. Call your authorized service representative.
PRINT QUALITY
• Label(s) did not get
printed within a multi label
print job.
• A portion of the printed
image was clipped off
and the beginning of the
next label was printed on
the same physical label.
1. If the serial interface is being used, verify that the correct
data protocol is selected to match the host interface
protocol. Print data may have been lost.
2. If Clip Page = Enable in the MEDIA SETUP menu, the
printer may have falsely detected a gap, hole, or black
mark and then clipped (discarded) the remaining printable
data for the label. To fix this:
a. Perform Auto Calibrate. See “Running Auto Calibrate”
on page 47.
b. Decrease Gap Threshold value by 2 or 3 increments.
See “Gap/Mark Thresh” on page 86.
c. Set Clip Page to Disable. Set Label Length to correct
physical length value. See “Clip Page” on page 80.
Media moves, but no image
prints in ONLINE mode. 1. Make sure the power supply cable has a good connection
to the right side of the printhead.
2. Place the printer offline and print the Checkerboard
diagnostic test pattern (see page 145). If the pattern prints,
there is a communication problem between the host
computer and the printer.
Media moves, but no image
prints in Direct Thermal
mode. 1. Media is not the type for direct thermal printing. Install
direct thermal media.
2. Direct thermal media is installed wrong side up. Reinstall
the media with the correct side facing the printhead.
