If the printer is not working properly, consult the following checklist. If the printer does not pass a step, follow
the corresponding troubleshooting suggestions.
Status
Response
Make sure that the Status LED
on the control panel green and
“Ready” is shown on the Smart
Panel program window.
• If the Status LED is off, check the power cord connection. Check the power
switch. Check the power source by plugging the power cord into another
outlet.
• If the Status LED blinks or lights red, solve the problems.
Print a demo page to verify
that the printer is feeding paper
correctly.
• If a demo page does not print, check the paper supply in the paper tray.
• If the paper jams in the printer, go to “Clearing Paper Jams”
Check the demo page to see if it
is printed correctly.
If there is a print quality problem, go to “Solving Print Quality Problems”
Print a short document from a
software application to verify that
the computer and printer are
connected and 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 that you are using the proper
printer driver and communication port. If the page is interrupted during
printing, go to “Solving General Printing Problems”
If completing the checklist
does not resolve the printer
problem, check the following
troubleshooting sections.
