Note: The product has a low ink alert system. The accuracy of this system depends on the user refilling the ink tanks correctly. The product cannot directly measure the ink levels in the tanks; instead it estimates the amount of ink remaining by internally monitoring ink usage. The low ink alert system may generate inaccurate messages if the ink tanks are not refilled according to these instructions. As a precaution, perform regular visual inspections of the ink tanks to ensure ink levels do not fall below the lower line. Continued use of the product when the ink level is below the lower line on the tank could damage the product. Parent topic: Solving Problems Running a Product Check Running a product check helps you determine if your product is operating properly. 1. Disconnect any interface cables connected to your product. 2. Load plain paper in the product. 3. Press the home button, if necessary. 4. Select Maintenance. 240
