Ink Consumption
• This printer uses ink cartridges equipped with a green chip that monitors information such as the
amount of remaining ink for each cartridge. This means that even if the cartridge is removed from the
printer before it is expended, you can still use the cartridge after reinserting it back into the printer.
However, when reinserting a cartridge, some ink may be consumed to guarantee printer performance.
• To ensure you receive premium print quality and to help protect your print head, a variable ink safety
reserve remains in the cartridge when your printer indicates that it is time to replace the cartridge.
Quoted ink yields do not include this reserve.
• Quoted yields may vary depending on the images that you are printing, the paper type that you are
using, the frequency of your prints and environmental conditions such as temperature.
• Do not use the cartridges that came with the printer for the replacement. The ink in the ink cartridges
supplied with your printer is partly used during initial setup. In order to produce high quality printouts,
the print head in your printer needs to be fully charged with ink. This process consumes a quantity of
ink and, therefore, these cartridges may print fewer pages compared to subsequent ink cartridges.
• To maintain optimum print head performance, some ink is consumed from all ink cartridges during
maintenance operations. Ink may also be consumed when you replace an ink cartridge or turn the
printer on.
• When printing in monochrome or grayscale, color inks may be used instead of black ink depending on
the paper type or print quality settings you are using.
