PQ-8P, PQ-8S

3.Send that command to the printer (press the Print Screen Button or print the document/file that contains the Host/PC download command). The self-test will print out in a few seconds.

Follow the steps below to start the self-test by setting the configuration switches.

1.Verify that the printer is connected properly to the PQ-8.

2.Power off the printer interface.

3.Set configuration switch SW1:8 (far right on the first switch bank) to “”. Verify that configuration switches SW1:1 through SW1:3 are not all set to “”, but are set to a valid Twinax Address.

4.Power on the PQ-8. A self-test will print within a few seconds after power up. After the self-test prints, the LED lights “Host Ready” and “Printer Ready” will begin blinking, indicating that the PQ-8 is not in operating mode.

5.Power off the PQ-8 and return configuration switch SW1:8 to the “o” position.

Two self-test pages will print if the PQ-8 is installed properly. Sample printouts are shown beginning on page 17. The selections shown in the samples are factory defaults. The numbers at the left margin are command numbers used to change this setting using Host/PC download commands (see Section 4.3).

If the test does not print, the PQ-8 failed the self-test. Call for technical support.

7.2 EBCDIC Hex Dump

The PQ-8 can be set up to print the buffer in hexadecimal EBCDIC code. This can be useful for a technician to diagnose problems with the PQ-8 or the printer.

The EBCDIC hex data is printed on a grid corresponding to the data’s position in the buffer. If the hex data represents a printable character, that character is printed below the hex data.

To start the EBCDIC Hex Dump through Host/PC Download:

1.Verify that the printer is connected properly to the PQ-8.

2.Type “&%Z42,1” on the screen.
