To keep printer's performance, Canon printer performs cleaning automatically according to its condition. When the printer performs cleaning, a small amount of ink is consumed. In this case, all colours of ink may be consumed. [Cleaning function] The cleaning function helps the printer to suck air bubbles or ink itself from the nozzle and thus prevents print quality degradation or nozzle clogging. The repairing parts for printers will be available five years after production is discontinued. Depending on your model, we may ask you to replace it with a new model, or one with almost the same performance as a maintenance service. In this case, you may not be able to use the supplies or accessories for the model or the compatible OS will be changed. To obtain good printing quality, use up ink within six months after opening. Depending on your terminal, such as a computer or a smartphone, or the operating system of your terminal, such as your computer or smartphone, the estimated ink level information or message displayed on the screen of your terminal may be different from the information or message displayed on the operation panel of the printer. Also, a part of the estimated ink level message displayed on the operation panel of the printer may not be displayed and/or may be displayed at a different point in time. Canon recommends that you use the information and message displayed on the operation panel of the printer as your reference. Note, however, that such information and message are displayed items serve only as a guideline information. Even when black-only or grayscale printing is selected, depending on the printing material and driver settings used, colour inks might still be consumed when printing. When the remaining ink level of any ink tank falls below the lower limit line, Canon recommends that you refill that ink bottle with the corresponding ink colour. The estimated page yield and/or print cost stated in brochures/catalogs/websites etc. is/are determined not based on the initial set of bundled ink bottles, but based on subsequent sets of ink bottles after print head nozzles have been filled with ink from the initial set of ink bottles. The warranty term for details, contact a Canon-authorized sales representative in the country or region you live in. The warranty covers only the printer main body excluding consumables such as print media and ink/ink bottles even during the warranty period. Ink bottles sold are generally meant for use with printers sold in the same region. The ink bottles may bear unique labels or configurations and may not be compatible for use with printers sold in another region. To ensure optimal performance of your printer, please check with your local Canon office or authorised Canon reseller before relocating your printer from the location of purchase. Using non-genuine inks may affect the printer's performance and/or the print quality. In some rare occasions, although there are no safety issues, using non-genuine inks has caused overheating of the print head and smoke emission from the print head due to the absence of an ingredient found in genuine ink. (Does not apply to usage of all non-genuine inks). Please take note that if the printer fault or breakdown is due to the usage of non-genuine inks, repair charges are applicable even if the claim is within the warranty period. Depending on your terminal, such as a computer or a smartphone, or the operating system of your the terminal, such as your computer or smartphone, the information or the message related to the estimated remaining capacity of the maintenance cartridge usage displayed on the screen of your terminal may be different from the information or message displayed on the operation panel of the printer. Also, the message for the estimated remaining capacity of the maintenance cartridge usage may be displayed at a different point in time. Canon recommends that you use the information and massage displayed on the operation panel of the printer as your reference.
