I always use HP ink. In December I used my printer to print out 100 news letters since I was using special paper I installed new HP ink. It did not contain enough ink to print out 100 pages.
I installed the 63Black XL/63 regular color and made 6 copies off a website and my HP OfficeJet 5255 chose the color cartridge and it used about 30%. WOW! Nest time I will pay closer attention and use only the black XL cartridge. A little disappointed with my copier that used too much color ink for a small job!
