PQ-8P, PQ-8S

7. Troubleshooting
If you need to ship the PQ-8, use
the original carton and packaging to
prevent damage.

7.1 PQ-8 Self-Test

Verify proper installation and
configuration of the PQ-8 by
performing a PQ-8 self-test. The self-
test prints out the current software
version, memory condition (RAM
and ROM), and configuration
selections.
NOTE
If you are operating a label
printer put the printer in
ASCII hex dump mode, then
follow the self-test
instructions below. If the
label printer starts printing,
the PQ-8 has passed the
self-test. To obtain a printout
of the current settings,
connect the PQ-8 to a laser
or dot-matrix printer.
The self-test can be started
through Host/PC download
command 98.
Follow the steps below to start the
self-test from your PC or terminal.
1.Verify that the printer is
connected properly to the PQ-8
and in “Ready” mode.
2.Type “&%Z98,1” on the screen.
This chapter provides instructions
for performing diagnostic tests on
the PQ-8. It also contains a problem
resolution guide that describes
common problems with the PQ-8 or
the printer and their solutions. If
you are unable to solve a problem by
following the procedures outlined in
this chapter, call for technical
support.
Before calling, verify that the
PQ-8 is installed correctly and that
its configuration settings are correct,
perform the appropriate diagnostic
tests outlined in this chapter, and
have the following information
ready:
• Printer and PQ-8 self-test
printouts
• Model number and serial
number of the PQ-8
• Description of the problem
• Results of diagnostic tests
• Type of host system or controller
You may also need to print an
EBCDIC hex dump by enabling the
EBCDIC Hex Dump option through
the PQ-8’s configuration switches.
This causes all printing to be in
hexadecimal EBCDIC code, just as
it’s received from the host, to help
in tracing problems.
