PQ-8P, PQ-8S

7.4 Self-Diagnostics

CAUTION

To avoid damage to your host system, the host must be disconnected before running this test.

The PQ-8 can be set up to perform a complete analysis of its functions. The PQ-8 transmits data to itself and then analyzes how that data is processed. If an error is detected, an error message is printed on the printer. Follow the steps below to perform PQ-8 self-diagnostics.

1.Power off the PQ-8.

2.Disconnect the host adapter from the PQ-8.

3.Set configuration switches SW1:1 through SW1:3 and SW1:8 to “”.

4.Verify that the printer is connected properly to the PQ-8 and in “Ready” mode.

5.Power on the PQ-8. The PQ-8 will start the self-diagnostics program and repeat it until it is powered off. After each completed self-diagnostic, the PQ-8 will send the following message to the printer:

TEST SEQUENCE COMPLETE

Because a laser printer will only print full pages, it will store these and other messages in the printer buffer until enough messages are accumulated to fill up one page.

6.Power off the PQ-8 to end the self-diagnostics program.

Any error messages are printed between the “TEST SEQUENCE COMPLETE” messages.
