Troubleshooting Checklist
If the printer is not working properly, consult the following checklist. If the printer 
does not pass a step, follow the corresponding troubleshooting suggestions.
Check Solution
Check the power cord 
and the power switch. 
Check the power source by plugging into another 
outlet. 
Make sure that the 
 LED is on. 
In the Ready mode, the  LED lights green. If the 
 LED lights red or blinks, go to “Troubleshooting 
Error Messages” on page 5.17. 
Press and hold the 
button to print a 
demo page.
• If a demo page does not print, check the paper supply 
in the input tray.
• If the paper jams in the printer, go to “Clearing Paper 
Jams” on page 5.6. 
Check the demo page to 
see if it is printed 
correctly.
If there is a print quality problem, go to “Solving Print 
Quality Problems” on page 5.11.
Print a short document 
from a software 
application to verify that 
the computer and printer 
are connected and are 
communicating correctly.
• If the page does not print, check the cable connection 
between the printer and the computer. 
• Check the print queue or print spooler to see if the 
printer has been paused.
• Check the software application to ensure you are 
using the proper printer driver and communication 
port. If the page is interrupted during printing, go to 
“Solving General Printing Problems” on page 5.3.
If completing the 
checklist does not 
resolve the printer 
problem, check the 
following troubleshooting 
sections.
• “Solving General Printing Problems” on page 5.3.
• “Troubleshooting Error Messages” on page 5.17.
