Maintenance cartridge, Ink system tips

Page 50 highlights

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. To check the status of the printheads: ● Press the key repeatedly until you see the printheads' status, or ● Select the icon, then Printhead information. 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 195. Electrostatic discharges are one of the main hazards to electronics products. This type of damage can reduce the life expectancy of the device. Maintenance cartridge Use the maintenance cartridge to clean and maintain the printheads, ensure the best possible print quality, and seal the printheads when they are not in use to prevent them from drying out. NOTE: The maintenance cartridge contains liquid. Therefore, store any maintenance cartridges upright and on a flat surface. Ink system tips For best results, always follow these guidelines: ● Install the ink cartridges, printheads, and maintenance cartridge before the install-by date, which is printed on the packaging. The expiration for the ink cartridges is the manufacturing date marked on the cartridge plus 30 months. ● Follow the instructions on the front panel during installation. 42 Chapter 5 Handle the ink system ENWW
