Review on HP CF380A Black Cartridge LaserJet by Pascal Santos

I bought a 312x cartridge (CF380X) and just installed it on Thursday evening, our office is closed Friday, Saturday and Sunday. This morning while making ONE copy I received a low black ink warning. I printed a report showing that I made 911 copies, which is VERY hard for me to believe as I've only printed 60 double-sided pages (120 total) since installing it. ). For this company's CF381A, CF383A, CF382A and CF380A cartridges, my report shows an estimate of 2,000 copies of which I made 728 copies on one cartridge and is 60 percent with over 1,450 copies remaining, my report shows this for all other colors in Series A I MUST get twice as much of Series X. I am VERY VERY disappointed in this mascara. Not only are we NOT worth the money, now I have to leave work for an URGENT trip to the office store. It not only cost our church money lost to ink costs, but also my time and labor. Not to mention it took a very long time to get the ink and they refuse to recognize our tax exempt status with Revane Marty Wicks, Administrative Assistant.
