Black Box PQ-8S Manual De Usuario

7. Troubleshooting

If you need to ship the PQ-8, use

the original carton and packaging to
prevent damage.

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.

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.
