The Canon Pixma iP4300 is an inkjet printer that can work with both PC and Mac computers using a basic USB connection. Each Canon Pixma iP4300 comes with a power cable for connecting the printer to an electrical socket. If you are having trouble turning your printer on, it could be a sign that there is a problem with your power cable or that your Canon Pixma iP4300 needs to be manually reset.
Check the connection on the back of the Canon Pixma iP4300 to make sure the power cable is firmly plugged into the proper port.
Plug the power cable into a different electrical socket and press the "Power" button to try turning on the printer again.
Unplug the power cable from the back of the printer and the electrical socket and replace it with another one. The Canon Pixma iP4300 will work with any standard two-pronged power cable. Then press the "Power" button to try turning on the printer again.
Hold down the "Power" button and the "Resume" button at the same time.
Release the "Resume" button when the printer starts to turn on, press "Resume" twice quickly and let go of both buttons.
Press the "Resume" button four times in a row when the green status light stops blinking.
Hold down the "Power" button until the printer turns off, wait a few minutes and press the "Power" button again.
