COMPACT BIDIRECTIONAL REVERSIBLE AUTOSWITCH

6.Troubleshooting

6.1Common Problems

1.Check all the cables. We recommend you use IEEE 1284 cables.

2.Use the optional AC power adapter. The Autoswitch is usually powered by the signal drawn from the computer and parallel device parallel port. However, if the computer or the device fails to supply enough power to the Autoswitch, a

9-VDC, 500-mA power adapter can be used. We recommend using the power adapter on inkjet printers like the DeskJet®.

3.Adjust the timeout. If you print long document files with graphics, or use a printer spooler, adjust the timeout to a higher value. This is because as the computer processes complex files, it pauses more often. If the pause is longer than the timeout window, the Autoswitch will assume that the transmission is over and prematurely finish the job.
