Review on 🖨️ HP 15X C7115X Black High Yield Toner Cartridge - Enhanced Performance for Exceptional Prints by Jeff Billingsley

We have had problems with these HP OEM cartridges before. I received a new cartridge and when I opened the undamaged box there was black toner inside. The cartridge is packed in a sealed black plastic bag. When I opened the bag, the inside was as clean as can be. Cartridge prepared and installed, tested. There were black bars on the test page. I took it apart and cleaned it up a bit. Rotate the glass tube to see if there are scratches. saw nothing Tried again and no luck. Run a cleaning cycle on an HP Laserjet 1200. Still no results. Product Return and Generic Trial.
