• One factor that will affect your color ink consumption is the cleaning cycles of the machine. The machine is designed to automatically flush and clean ALL of the ink jet nozzles on a programmed schedule. A periodical cleaning or "flushing" of all the ink cartridges occurs approximately every two days. During the cleaning process, the machine draws out a small amount of ink to remove air bubbles from the cartridge and to remove dust and dried ink from the ink nozzles and channels. This not only ensures premium print quality but also ensures the life of the print head. Because of the ink jet technology, this process is common to all ink jet machines.

• Another factor that could be affecting your color ink consumption is the amount of printing from a computer, even if the print jobs are black only. Because this machine offers full color printing, the default setting in the print driver is COLOR. This means the machine will automatically mix ALL the colors to produce a selected color, even black.
  
  If you would like to print from the computer using the black ink only, you need to change the printing preferences to GRAY SCALE, and also select "Plain Paper" at Media Type.
  If you select other Media Type than "Plain Paper", color inks are used. In detail, please refer to the Related FAQ which is located in the end of this page:
  "When selecting grayscale printing in the printer driver,does this use only the black ink or all the ink cartridges to produce the grayscale image?"
