SATO CL412E service manual Initial Check List, IEEE1284 Parallel Interface

Section 8. Troubleshooting

8.2 Initial Check List

If you are unable to produce output on your printer, check the following before deciding you're unable to proceed any further.

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 or the Label Hold-Down is not closed and latched in position.

3.Are the Label and Ribbon lights on the front panel Off? If these lights are On, the labels or ribbons may be incorrectly loaded.

8.3 The IEEE1284 Parallel Interface

1.Is the IEEE1284 printer cable connected securely to your parallel port (DB25S Female) on the PC and to the Centronics 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 IEEE1284 specifications? If it does not and you are connected to an IEEE1284 or ECP parallel port on the computer, the printer may not be able to communicate correctly.

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

4.Is the IEEE1284 Interface Module installed in the printer? Older versions of the Parallel Interface module will not work correctly in the CL408e/CL412e printers.

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 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 ON-LINE.

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.

6.When you send the print job to the printer and it does not respond and there is no error message on the PC:

a.Check your data stream for some of the basics. Is your job framed as follows: <ESC>A—Data—<ESC>Z

b.Verify that you've included all required parameters in the data stream.
