HP Latex Optimizer consists of positively-charged (cationic) polymers suspended in a colorless, water-based ink vehicle. It reacts with the ink pigments, which are negatively-charged (anionic), to immobilize them rapidly on the print surface. This produces sharp text and image detail by suppressing feathering and color bleed especially at high productivity levels. HP Latex Optimizer also enables the drying and curing process of the HP Latex inks to operate at lower temperatures and to be more energy-efficient, which has the additional benefits of allowing wide substrate support and reduced power consumption. CAUTION: Avoid touching pins, leads, and circuitry when handling ink cartridges because these elements are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. See Glossary on page 173. Electrostatic discharges are one of the main hazards to electronics products. This type of damage can reduce the life expectancy of the device. Printheads The printheads deposit ink on the substrate. Each printhead, except the optimizer printhead, is connected to two ink cartridges. 118 Chapter 6 The ink system ENWW

Ink cartridges
The printer's seven ink cartridges provide magenta, light magenta, black, yellow, light cyan, cyan, and
optimizer ink to the printheads. Each cartridge has a capacity of 775 ml.
Ink cartridges require no maintenance or cleaning, but must be shaken before installation. High-quality
printing results continue even when the ink levels are getting low.
HP Latex Optimizer enables high quality at high speed. HP Latex Optimizer consists of positively-charged
(cationic) polymers suspended in a colorless, water-based ink vehicle. It reacts with the ink pigments, which
are negatively-charged (anionic), to immobilize them rapidly on the print surface. This produces sharp text
and image detail by suppressing feathering and color bleed especially at high productivity levels.
HP Latex Optimizer also enables the drying and curing process of the HP Latex inks to operate at lower
temperatures and to be more energy-efficient, which has the additional benefits of allowing wide substrate
support and reduced power consumption.
