Replacing Ink Cartridges Before you begin a large print job, you should check your ink levels. If one of your cartridges is low, you can replace it before you start. Or you can wait until the ink runs out, replace the cartridge, and then continue the job without any loss of print quality. However, it is best to replace a low ink cartridge before starting a large print job. The easiest way to check ink levels is from the control panel LCD display. The numbers below the ink icons on the LCD display correspond to the 8 ink cartridge slots on the printer. The icons show the percentage of ink remaining as follows: 100-81% 80-61% 60-41% 40-21% 20% or less Ink low Ink out Cartridge error or no cartridge 5-127
