Troubleshooting
Checking the Indicator Lights
This chapter contains information to help you solve printer
problems. A problem may have one or a combination of causes,
including a malfunction in your computer, software, the printer
cable, or the printer. Many printing problems are related to how
your software interacts with the printer.
If your printer is not operating properly, try the suggestion in this
chapter to isolate and solve the problem.
NOTE: If you have a problem with your printer and you cannot
resolve it by referring to the information in this chapter, contact
the Canon Computer System Technical Support help desk at 1-
800-423-2366. Attempting to repair the printer yourself may
void the warranty.
If you have a problem with your printer, check the indicator lights. The
indicator lights and the printer alarm notify you of the following
problems:
Problem: AC adapter is not connected.
Solution: Make sure the AC adapter is connected securely
to the printer and to the wall outlet.
