The ink system 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. See Glossary on page 87. 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 kit The printhead cleaning kit contains the printhead cleaning cartridge, the ink funnel and the ink filter. 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 printheads. You are notified when 92% of the roll has been used, after which the cartridge should continue to function for at least another 140 m² (1500 ft²) of printed area. A new roll lasts for at least 1850 m² (20000 ft²) of printed area. 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. ENWW Ink system components 77
