Good question. This is a laser printer so it does not take ink cartridges. It takes toner cartridges. It has 1 black, cyan, magenta, and yellow toner so that is a total of 4 toners. It takes HP 410A and 410X toners. The 410X toners are the high yield toners that have a higher page yield.
The standard yield toners all print up to 2,300 sheets. The high yield black toner prints up to 6,500 sheets and the high yield color toners print up to 5,000 sheets.
I hope this helps.
