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.
