PRINT QUALITY
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 61.
b. Decrease Gap Threshold value by 2 or 3 increments.
See "Gap/Mark Sensor" on page 90.
c. Set Clip Page to Disable. Set Label Length to correct
physical length value. See "Clip Page" on page 108.
See "How To Maximize Printhead Life" on page 194.
1. Print a checkerboard diagnostic test pattern (page 196). If
the pattern prints, there is a communication problem
between the host computer and the printer.
2. Make sure the J402 power supply cable has a good
connection to the right side of the printhead.
1. Print a checkerboard diagnostic test pattern (page 196).

Reinstall media.
4. Check that the Label Width value in the QUICK SETUP or

installed.
5. Check that the Print Intensity value is not set too high in
the QUICK SETUP or MEDIA CONTROL menu.

pressing down on both sides of the pivoting deck. Make
sure the latches on each side of the pivoting deck are
