Review on HP 304A Toner-Cartridges Bundle - Cyan, Yellow, Magenta (CC531A, CC532A, CC533A) - High Quality Printing Solution by Ken Martinez

I don't print large volumes of documents. When I do this, they are about 90% black text. I installed these cartridges in August 2016 and in the first week of November I'm getting messages that I'm out of yellow toner. In that time I've printed no more than 750 sheets of paper, with more than double that being the norm. Cartridges usually last about a year for me. I'd love to leave the rave reviews that other buyers have, but now I'm faced with having to buy another yellow cartridge when I don't think it's necessary.
