Your printer uses an advanced built-in printhead. The system is designed to provide excellent image and text quality, while eliminating the need to purchase new printheads every time you replace ink cartridges, and saving you money. The printing system requires that both the black and color ink cartridges be installed to print. If either cartridge is not installed or is out of ink, the printer or printhead will not print correctly.
In some cases when you print or copy a text document, the text may actually be a shade of grey rather than true black. In this case a combination of black and color inks are used to print the text. Also, if you print or copy black and white photos, a combination of color inks are used from the color ink cartridge.
Printers with this capability are not the type of printers with permanent or built-ink printheads. The capability exists only in printers having the printhead as a integral part of the ink cartridge, which adds to the overall cost of printing. The all-in-one printer uses a built-in printhead, removing the need for customers to purchase a new printhead with every replacement ink cartridge, which allows us to pass on substantial savings to our customers.
