Review on ZIPRINT Compatible Cartridge Replacement Laserjet Computer Accessories & Peripherals by Julio Fernandez

When I first received these toner cartridges I was very pleased with the print quality. It was just as good as HP. A few months after printing about 1,500 pages, the cyan toner cartridge started leaking, causing every printed page, even black and white, to turn blue. I've put the printer through countless cleaning cycles, removed and reinserted cartridges, but nothing has improved the situation. I ended up having to order a replacement HP cyan cartridge and now it works perfectly. I think you get what you pay for. I will try another brand of cartridges but I will not buy these again.
