Ink Supplies For optimum results from the printer and modular ink delivery system always follow these guidelines when handling the ink supplies:
• 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. • Allow the Printer and the Maintenance Cartridge to automatically clean the Printheads. • Follow the instructions on the front panel of the Printer during installation. • Avoid unnecessary removal of the Ink Cartridges and Printheads. • When turning off the Printer always use the power Off button on the front panel. The Printheads are then stored correctly which prevents them from drying out.
• The Ink Cartridges should never be removed while the printer is printing. They should only be removed when the printer is ready for you to replace them. The front panel will guide you through the removal and installation procedure. General Precautions When Handling Ink Supplies CAUTION: Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the printhead. • Handle the ink supplies with care. In particular the Printhead, which is a high precision device and must be handled carefully. • Do not touch the Printhead nozzles. • Do not put the Printhead down on the nozzles. • Do not be rough when handling the Printheads. Always set them down gently.
