Review on 🖨️ Uniwork Toner Cartridge Replacement for HP 30A CF230A 30X CF230X | Laserjet Pro MFP M203dw M227fdw M227fdn M203d M203dn M227sdn M227 M203 Printer | 2 Black by Scott Holland

I really wanted to like these cartridges. They were reasonably priced for 2 packs but if one of the cartridges DOES NOT HAVE A CHIP the printer had to recognize it. Replacement will void all savings. Unfortunately, the one missing the chip was the second one in the box, so I didn't find out until after the 30 day return window. IF I EVER buy these replacement cartridges again I will be sure to TEST both cartridges upon receipt to make sure the chip is there. If anyone has any tricks or tips on how to remove and attach the chip to an old cartridge, please share your knowledge! Thanks in advance!
