The black cartridges are not a good investment. Each of the cartridges I tried (3 of 5) did not produce acceptable results. The black was not really black, but more of a gray color. I followed the instructions, cleaned,calibrated, printed test pages on each and the results were the same with each cartrudge I tried..The cartridges actually acted like they were already dried out even though they were packed in sealed packages.Frustrated I purchased a new black cartridge from a retailer, intalled it and had no further issues.Save your money.
