PQ-8P, PQ-8S

7. Troubleshooting

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.

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.
