Handle the ink system

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 66. Electrostatic discharges are one of the main hazards to electronics products. This type of damage can reduce the life expectancy of the device.

Printhead cleaning cartridge

The printhead cleaning cartridge cleans and maintains the printheads, and seals the printheads when they are not in use to prevent them from drying out.

The cartridge contains a roll of cloth, which is used to clean the cartridges. You are notified when 90% of the roll has been used.

The printer will refuse to start a print job if it detects the end of the cleaning roll. You should then replace the printhead cleaning cartridge with a new one.

Ink funnel

The ink funnel collects waste ink produced during printhead servicing. It is important that this funnel is installed, as it prevents significant deposits of ink over various other printer parts.

From the ink funnel, the waste ink passes through a tube into the printhead cleaning container.

Printhead cleaning container

The printhead cleaning container stores waste ink collected by the ink funnel..
