I bought this "valuetoner" 2-pack black ink cartridge instead of the more expensive HP black ink cartridge because I wanted to save some money by getting a "universal " instead of "brand name". I put the first cartridge in and printed 4 pages with no problems. When I tried to print a 1 sided document I noticed that 3/4 of the pages were smeared with ink causing the document to be unreadable Then my printer is asking me to replace the black ink cartridge Second cartridge installed today 2/28 .21 I hope I can print more than 5 pages before this cartridge fails Note to self: next time spend more money and buy brand name replacement ink cartridges! I will never buy this product again.
