2.1.1.4 Ink Supply Mechanism
The two ink cartridge holders each hold three cartridges, K, C, and M on one
side and Lc, Lm, and Y on the other side. The design of the holders makes it
quite easy to install and replace ink cartridges from the front of the printer. The
I/H Lever opens and closes the I/H door, and at the same time it changes the
angle of the Ink Cartridge Holder Assembly as shown in Figure 2-16, "Ink
Supply Mechanism". To prevent users from accidently installing a color ink
cartridge in the wrong slot, the cartridges have slightly different designs. Stylus
Pro 9000 dye ink cartridges have the same physical shape, so they can be
inserted in each color's ink cartridge slot, but in order for the ink cartridge's type
to be distinguished by the ink ID sensor, the message "Replace ink cartridge" is
displayed in the LCD panel and printing is not possible. See "I/H Assembly
Sensors" on page 64 concerning sensor details.
Another important feature of the ink cartridge holders is the ink valve, which is
located on the outer sides of the ink cartridge holders and shuts off the flow of
ink during printer transportation. The valve close under the following
conditions:
n
The user turns the valve to the "CLOSE" position to transport the
printer.
n
The I/H lever is lifted to the up/cartridge install position.
The ink flows out of the ink cartridges, through stainless steel pipes, through
ink tubes, and finally into the printheads.
