Troubleshooting

Initial Checklist

1.Is the Printer powered up and ONLINE?

2.Do any of the Front Panel LEDs indicate an error condition? If the Error LED is lighted, it may mean the print head assembly is open.

3.Is the Print Head in the down and latched position?

Using the IEEE 1284 Parallel Interface

1.Is the IEEE 1284 printer cable connected securely to your parallel port (DB-25S Female) on the PC and to the Parallel Interface connector on the printer?

Warning : Never connect or disconnect interface cables (or use a switch box) with power applied to either the printer or the host. This may cause damage to the interface circuitry and is not covered by warranty.

2.Does the Parallel interface cable used meet IEEE 1284 specifications?

3.Is there more than 1 parallel interface port on your PC (LPT1, LPT2, etc.)? If so, make sure you are sending data out of the correct port.

4.Is the IEEE 1284 interface selected? DSW-8 must be in the ON position to enable the Parallel interface.

5.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 does not 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 computer, but at this stage, a defective cable may be one of the reasons.
