Replacing an Ink Tank When remaining ink cautions or errors occur, the message will appear on the touch screen to inform you of the error. Take appropriate action according to the message. A Message Is Displayed Note • If print results become faint or white streaks appear despite sufficient ink levels, see Maintenance Procedure. Replacing Procedure When you need to replace an ink tank, follow the procedure below. Important • If you remove an ink tank, replace it immediately. Do not leave the machine with the ink tank removed. • Use a new ink tank for replacement. Installing a used ink tank may cause the nozzles to clog. Furthermore, with such an ink tank, the machine will not be able to inform you when to replace the ink tank properly. • Once an ink tank has been installed, do not remove it from the machine and leave it out in the open. This will cause the ink tank to dry out, and the machine may not operate properly when it is reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use. Note • Color ink may be consumed even when printing a black-and-white document or when black-andwhite printing is specified. Every ink is also consumed in the standard cleaning and deep cleaning of the print head, which may be necessary to maintain the performance of the machine. When an ink tank is out of ink, replace it immediately with a new one. Useful Information about Ink 1. Make sure that the power is turned on, then, holding both sides of the paper output tray, gently open it. 2. Lift the operation panel and open until it stops. The print head holder moves to the replacement position. 205
