How to Diagnose Problems
Use the following list to determine the cause of printing problems:
1
Verify that the printer is working properly.
• Is the printer working? First check that the printer can generate a diagnostic/ configuration
page. See
“Printing a Configuration Page” on page 155
.
• Is the printer online? Verify that the printer is online (ready) or nothing will print.
• Does a printer error occur?
2
Check the ERROR LED on the printer panel is not lit or not blinked.
3
Check the configuration page to see what protocols are enabled and active.
• See the appropriate chapter to confirm that you have installed and configured your network
protocol correctly for the printer.
4
If you added any new software applications, make sure that the program is
compatible and installed correctly on the network. See your network protocol
documentation to confirm.
