Canon BJC 3000 Reference Manual page 324

Printer problem
If the printer will not operate, or if the POWER lamp flashes orange and
green alternately with beeps, contact a Canon service facility. Count the
number of flashes and beeps. (You may be asked for this information.)
Hardware problem other than the printer
If the printer is operating normally and the settings in the application pro-
gram are also correct, there may be a problem with a printer cable or in the
computer system (e.g., memory, hard disk, interface). Contact your hard-
ware manufacturer.
Application program problem
Problems that arise only when you use a particular application program are
probably caused by the application program. For details, consult your soft-
ware manufacturer.
The problem may also be solved by installing the latest version of the
printer driver.
