Hi Gibsond2015.
When replacing the ink, the printer will need to be powered on. If the printer is powered off or unplugged while the inks are replaced, then it will work off of the last-known-correct ink levels from the old ink cartridges, and not recognize new inks.
If the inks were replaced while the printer was powered on, then you are using third-party, refilled, or remanufactured ink tanks. Canon genuine ink tanks are not designed to be refilled, and the "low ink" error message does not itself cause internal damage.
Canon USA does not recommend the use of inks manufactured by third parties in Canon printers.
Canon genuine inks are formulated specifically for use in our ultra-precise print head. Our print head and inks work together as a precisely engineered system to support optimum image quality, print speed and reliability in higher resolution text and color printing applications.
Canon supplies and accessories can be purchased online at http://shop.usa.canon.com/, or by calling 1-800-385-2155 to speak to a Canon Direct Representative.
Should you decide to use inks manufactured by third parties in your Canon printer, and such inks cause damage to your product, this damage will not be covered under the product's limited warranty. Any repairs required as a result of such damage must be made at your expense.
