How to Reset a Pixma MP140

The Canon PIXMA MP140 is a popular color desktop home printer that also serves as a scanner/copier. In some cases, the printer may not realize that you have installed a new ink cartridge and will thus not reset the ink levels. With the reset function of the PIXMA MP140, you can quickly restart the unit and get back to printing normally.
