● Always disconnect cartridges from the printer before handling them. ● Never place anything heavy-more than 1 kg (2.2 lb)-on top of a cartridge. ● Take care not to drop a cartridge. ● Do not try to force the last of the ink out of an almost-empty cartridge by pressing the ink bag inside the cartridge. Ink cartridges require no maintenance or cleaning, but you must follow the instructions on the label before installation. High-quality printing results continue even when the ink levels are getting low. CAUTION: Non-genuine or altered cartridges or intermediate tanks are not supported by the printer; if they are detected, printing is stopped. Printheads The printheads deposit ink on the substrate. Each printhead, except the optimizer printhead, is connected to two ink cartridges. The printheads are extremely durable and do not need to be replaced every time an ink cartridge is replaced. They provide excellent results even when the ink cartridges contain a low level of ink. To maintain optimum print quality, the printheads are automatically tested at regular intervals, and automatically serviced when necessary. This takes a little time and can occasionally delay printing. When a printhead eventually needs to be replaced, the front panel will display a message. CAUTION: Avoid touching pins, leads, and circuitry when handling printheads because these elements are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. Electrostatic discharges are one of the main hazards to electronics products. This type of damage can reduce the life expectancy of the device. CAUTION: If you want to remove a printhead from the printer and preserve it for later use, reinstall the cap and plug, but never install a clear optimizer cap or white plug on a non-optimizer printhead. Optimizer printheads have clear caps and white plugs, while the other printheads have orange caps and plugs. Installing the wrong cap and plug can cause irrecoverable printhead damage. Maintenance cartridge The maintenance cartridge cleans and maintains the printheads, and seals the printheads when they are not in use to prevent them from drying out. It is also used to store waste ink. ENWW HP Latex 570 ink system 135

Non-genuine or altered cartridges or intermediate tanks are not supported by the printer; if they are

Printheads
The printheads deposit ink on the substrate. Each printhead, except the optimizer printhead, is connected to two
ink cartridges.
The printheads are extremely durable and do
not
need to be replaced every time an ink cartridge is replaced.
They provide excellent results even when the ink cartridges contain a low level of ink.
To maintain optimum print quality, the printheads are automatically tested at regular intervals, and automatically
serviced when necessary. This takes a little time and can occasionally delay printing.
When a printhead eventually needs to be replaced, the front panel will display a message.
CAUTION:
Avoid touching pins, leads, and circuitry when handling printheads because these elements are
sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. Electrostatic discharges are
one of the main hazards to electronics products. This type of damage can reduce the life expectancy of the
device.
CAUTION:
If you want to remove a printhead from the printer and preserve it for later use, reinstall the cap and
plug, but never install a clear optimizer cap or white plug on a non-optimizer printhead. Optimizer printheads
have clear caps and white plugs, while the other printheads have orange caps and plugs. Installing the wrong cap
and plug can cause irrecoverable printhead damage.
