Troubleshooting Checklist
If the printer is not working properly, complete the following checklist in order. If the printer
does not pass a step, follow the corresponding troubleshooting suggestions.
Check
Make sure that the
Data
light on
the control panel is on.
Press the
Demo
button to print
a demo page to verify that the
printer is feeding paper correctly.
See page 7.6.
Check the demo page to see if it
is printed correctly.
Print a short document from a
software application to verify the
computer and printer are
connected and are
communicating correctly.
If completing the checklist did
not diagnose the problem with
the printer, check the following
troubleshooting sections.

connection. Check the power switch. Check the
power source by plugging into another outlet.
