General Information About the Ink Supplies
For optimum results from the printer and modular ink delivery system always follow these guidelines when handling the ink supplies:
n Always install the Ink Cartridges and Printheads before the n n n n
n
expiration date, which is on the packaging. Install Ink Cartridges and Printheads in their color-coded slots. 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 located on the left hand side of the Printer. 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. See page Page 3-6, When Should You Replace the Ink Cartridges?
