Rated 4.5 out of 5�by 2 reviewers.
Rated 4 out of 5�by GOOD JOB We have been using our printer for two years now. This cartridge works great. Never had any paper jam problems. The price is a little high and there is no high quality cheap refilled ones available. we tried a few different refilled ones and they were all not very satisfactory. The original one works very well. July 19, 2011
Rated 5 out of 5 Genuine HP toner or inkjet cartridges are the only way to go. Every compatible I have ever purchased gave bad print quality and needed replacing MUCH faster than the branded items. Pay a little more, but get a huge amount of extra savings in the long run. June 27, 2011
