Modular Ink Delivery System
A modular ink delivery system is the separation of ink cartridges and printheads into
individual, single-color components. Traditional inkjet printers use one black and one tri-
color ink cartridge, each with integrated printheads. HP's modular ink delivery system
features four separate ink cartridges--one for each primary printing color--and four
corresponding long-life printheads, with tubes connecting the components. Including the
standard and high-capacity black ink cartridges, there are actually nine consumables, with
only eight used in the printer at one time.

Technology Update
How It Works
By separating the ink cartridge from the printheads, a modular ink delivery system allows
the ink supply to remain in a permanent, fixed position. The printheads remain attached
to the carriage and move back and forth, delivering ink to the page as the paper advances
through the printer. Each printhead and ink cartridge is embedded with a tiny memory
device called a smart chip that recognizes and stores the unique operating characteristics
of the component to create a totally integrated printing system that ensures consistent,
high-quality printing at the lowest cost available.
A unique pressurization system maintains a constant supply of ink to the printheads.
Smart chips monitor the amount of ink used by counting every drop that passes through
each printhead. When the smart chips sense more ink is needed to maintain continuous
printing, a plunger in each cartridge temporarily pressurizes the cartridges to deliver more
ink to the printheads. With the modular ink delivery system, ink supply is instantly
replenished, even at top speeds.
The new, individually replaceable printheads are designed for long life and each should
print 12,000 pages in black, 24,000 pages in color. As a result, you'll go through many
ink cartridges before the corresponding printhead will need replacement. With their
modular design, ink cartridges contain twice the ink supply of current HP cartridges, so
you'll also get longer lasting cartridges. When a component approaches the end of its
print life, the smart chip notifies the user through on-screen messages so a replacement
can be purchased prior to the part expiring.
By separating the printheads and ink cartridges, you only replace the component that is
no longer usable. Printheads can be replaced one at a time without the need for costly or
extensive servicing and aren't discarded when the ink is expended. HP printheads also use
a wet wiping system to eliminate nozzle clogging that plagues other permanent printhead
designs. Component replacement is easy. Simply pull out the used part and snap in a
replacement.
