TROUBLE- 9 SHOOTING Troubleshooting Solving Communication Problems ? Solving Communication Problems If There is a Problem Communicating between Your Computer and the Printer Some symptoms of a communication problem are: - The front-panel Receiving light does not come on. - The front-panel display does not show STATUS / Receiving. - Your computer displays an error message when you are trying to print. - Your computer or printer "hangs" (stays idle) while communication is taking place. - Your printed output shows random or inexplicable errors (misplaced lines, partial drawings etc.) Items to start checking are: Have you selected the correct interface port in your software? Does the printer work correctly when receiving files from other software? If the printer is connected to a network, try using it when connected directly to your computer. If your printer is connected to your computer via any other intermediate devices, such as switch boxes, buffer boxes, cable adapters, cable converters etc., try using it when connected directly to your computer. Try another interface cable. For details of supported cables, see page 11-8. 9-9
