When the message Check Ink Levels is displayed on the control panel screen, you need to refill the ink and replace the chip unit soon. Obtain an ink pack of the appropriate color as soon as possible.
You will be unable to print if a chip unit needs to be replaced. If the Check Ink Levels message is displayed during a print job, the print job pauses while you refill the ink and replace the chip unit. You can use the same procedure to refill the ink and replace chip units for all colors.
If the procedure for refilling the ink and replacing the chip unit is not followed correctly, the remaining ink warning system may not function properly. To prevent this, replace the chip unit and refill the ink as soon as possible once the remaining ink level falls below 2.8 in. (70 mm) from the base of the ink tank.
