Ink
Ink is used for various purposes other than printing.
Ink may be used for purposes other than printing.
When you use the Canon printer for the first time after you install the bundled ink tanks, the printer
consumes a small amount of ink in the amount to enable printing by filling the nozzles of the Print Head
with ink. For this reason, the number of sheets that can be printed with the first ink tanks is fewer than the
succeeding ink tanks.
The printing costs described in the brochures or websites are based on the consumption data from not the
first ink tank /ink cartridge but the succeeding ink tank /ink cartridge.
Ink is sometimes used to maintain the optimal printing quality.
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 colors 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.
In addition to cleaning the print head, the printer automatically performs the system cleaning at regular
intervals to prevent trouble such as unwanted lines or the complete stopping of ink ejection.
If the remaining ink level is low, the system cleaning may not be performed automatically. Follow the
message displayed on the LCD to replace the deficient ink tank with a new one.
There will be some ink remaining in the ink tank removed for replacement to perform the system cleaning.
Important
• The used ink is ejected into the maintenance cartridge. When the maintenance cartridge becomes
full, replacement is necessary. If the displayed message indicates that the maintenance cartridge is
nearly full, promptly obtain a new one.
Replacing the Maintenance Cartridge
• A certain amount of ink is consumed in regular operations performed automatically to keep printer
performance, such as print preparation, ink path bubble removal and print head cleaning. The
maintenance cartridge is also consumed for this operation.
• When using the printer for the first time after installing the ink tanks which are bundled with the
printer, a certain amount of ink is consumed to set up the printer for printing. For this reason, the
printable volume of the ink tanks which are bundled with the printer will be less than that of
subsequent replacements. Since the maintenance cartridge is filled with the ink which is ejected for
the initial set up mentioned above and its remaining capacity is consumed approximately 50%, the
timing of replacing the maintenance cartridge becomes sooner than that of subsequent
replacements.
Black-and-white printing uses color ink.
Black-and-white printing may use ink other than black ink depending on the type of printing paper or the
settings of the printer driver. So, color ink is consumed even when printing in black-and-white.
