The Canon i320 is a simple value-priced, bubble jet printer. Printing speeds are up to 10 pages per minute (ppm) in black and 7 ppm in color. It's unique at this level to have true edge-to-edge printing for borderless prints. Rarely, you may have to replace the entire print head rather than just the tanks.
Instructions
1. Pull the front cover open with your finger. It will come forward and rest on the paper output tray. The print head is under the front cover. If you take a look at the printer, you'll see that there's an operation panel on the top right with some buttons and indicator light. The front of the printer is an expanse of undecorated plastic. Between the operation panel and the front you'll see a crease with a finger-tip sized indentation in the middle of the crease. That's where you insert your finger to open the cover.
2. Unlock the print head lock lever. You should be looking inside the printer. You will see a square box open at the front and top with two ink tanks in it. The box will be attached to bars deep inside the printer. The box is the print head holder. Flip up the gray lever which is the print head lock lever.
3. Grasp the print head and remove it from the print head holder. Lift it up and out of the printer.
4. Replace the print head. Just follow these instructions in reverse. Install the new print head into the holder and snap the grey lever down on it and close the cover.
