The PIXMA MP620 is an all-in-one printer released by Canon in 2008. This printer is capable of printing high-quality photographs with a maximum color DPI resolution of 9,600-by-2,400. The high-quality prints are made possible by five separate ink tanks that must be replaced regularly if you use the printer often. You can purchase these tanks at any office supply store and you can easily install them yourself.
Press the "Power" button on your printer to turn it on.
Open the paper output tray on the front of the unit. This is the tray the finished prints are ejected on to.
Lift the plastic cover that holds the scanner tray up until it locks into place. The print head that holds the ink tanks will automatically slide out into position.
Pull out the spent ink tank, wrap it in a plastic bag to prevent leaks and set it aside.
Unwrap your replacement tank. Pull the orange sticker off the tank. Press down the button on the orange protective cap and twist it counter-clockwise to remove it.
Slide the ink tank into the appropriate slot in the print head. Press the ink tank down where it is marked "Push." It will click into place. Close the lid to complete the process.
Your empty ink tanks can be recycled at many office supply stores. Some even offer discounts on new tanks.
