Serious company My advice: Use HP branded OEM toner cartridges, they deliver excellent colors and do not bleed over the entire printer drum. I will ready to buy from this seller again. My experience is 2800 pages per toner. By the way, if you're thinking, "Oh, one of my color toners is almost empty and I only print in black and white", the printer will not work if one of the colors is empty. I think B&W still uses some color for tones. Just thought I'd post this in case you're low on color and think I'm fine. I have found another seller for a little less but I am sticking with this trusted and trusted supplier.
