I received these cartridges on January 17th, mostly I only print in black as it is an office printer used for printing receipts and prints a maximum of 30 pages per week on average in a small office . There was no way to use enough black ink to already empty one cartridge and use 1/3 of the second cartridge. Since this printer is also less than a month old I can easily return it and buy a different brand. The quality of HP products has really gone down.
