Solution/Explanation
Power Failures
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.
1. If the serial interface is being used, verify that the correct
data protocol is selected to match the host interface
protocol.
2. If Clip Page = Enable in the MEDIA CONTROL 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 72.
b. Decrease Gap Threshold value by 2 or 3 increments.
See "Gap/Mark Thresh" on page 140.
c. Set Clip Page to Disable. Set Label Length to correct
physical length value. See "Clip Page" on page 131.
1. Make sure the J402 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 239). If the pattern prints,
there is a communication problem between the host
computer and the printer.
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.
