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.

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 expended Cartridge error or no cartridge When the red B Ink light is flashing and INK LOW appears on the LCD display, the indicated cartridge is almost expended. Make sure you have a replacement cartridge. When the light stays on and REPLACE INK CARTRIDGE is displayed, the cartridge is expended. You must replace the cartridge before you can continue printing.
