Switch Black Ink Type

Your product comes with Matte Black and Photo Black ink cartridges. Although both cartridges must be installed for your product to work, it can print using only one type of black ink at a time.

Your product switches the black ink type automatically, depending on the type of media you load. Because this process consumes some ink, so you should avoid switching black ink more often than necessary and select a default black ink type for the type of media you print on most often.
Note: To disable automatic black ink switching, press the  setup button and select System Administration > Printer Settings > BK Ink Auto Change > Off.
