Term Definition
Printheads The printheads are the components in the print mechanism that apply ink to the paper. There are two
printheads: a black ink printhead and a tri-color ink printhead. Once the printheads are installed, they
should not be removed from the print carriage.
Printhead latch The printhead latch on the carriage secures the printheads in the carriage. The printhead latch should not
be opened after the printheads are installed and the ink system has primed.
Ink tanks Ink tanks are external ink reservoirs located at the right side of the printer. There are four ink tanks. Each
ink tank corresponds to an individual color: black, cyan, magenta, and yellow.
Ink tank caps Ink tank caps are rubber plugs that seal each ink tank.
Ink valve The ink valve switch on the side of the ink tank controls the flow of ink between the tanks and the
printheads. For more information, see Ink valve on page 56
Priming Priming is the process of filling the ink supply tubes that run between the ink tanks and the printheads.
This process occurs when you install new printheads and start the priming process from the control panel.
For more information about priming, see Printhead priming and alignment icons on page 12 .
Alignment Alignment is a process of aligning the printheads to improve print quality. For more information about
alignment, see Printhead priming and alignment icons on page 12 .
