Check 1
Have you pressed the POWER button firmly?
Press the POWER button fully down, then release it. If you do not press the
button hard enough, the printer may not turn on.
Check 2
Is the power cord plugged in?
Make sure that the power cord is plugged into a power outlet.
Check 3
Is the power outlet live?
Connect another electrical device to the same power outlet. If the other
device operates normally, the power outlet is functioning normally.
After you perform all three checks, if the problem is not solved unplug the
printer and contact a Canon service facility.
