General Troubleshooting Guide
5.1 INITIAL CHECKLIST
1. Is the printer powered up and ON LINE?
2. Is the ERROR light on the front panel OFF? If this light
is ON, it may mean the print head assembly is open or
another error condition is present.
3. Are the Label Hold-Down and Print Head Assembly in
the latched position?
5.2 USING THE CENTRONICS (PARALLEL) INTERFACE
1.
Is the IBM parallel printer cable connected securely to
your parallel port (DB-25S Female) on the PC and to
the Centronics connector on the printer?
2.
Is there more than one parallel interface port on your
PC (LPT1, LPT2, etc.)? If so, make sure you are send-
ing data out the correct port.
3.
When you send the print job to the printer, and it does
not respond, do you get an error message on your PC
that says "Device Fault" or something similar?
This may mean that the computer doesn't know the
printer is there. Verify that:
a. Both ends of the cable are securely inserted into
their respective connectors.
b The printer is ONLINE.
c. The cable is not defective. There are other things
that can cause this error message on your com-
puter, but at this stage, a defective cable may be
one of the reasons.
