I received this printer for free when my original HP printer broke down. When I ran out of ink in an original HP cartridge, I decided to refill the cartridge myself. After I installed it, the printer showed an error message stating "incompatible print cartridge (black)." Now, the only way I can use the printer is to either buy a new expensive HP cartridge or just remove it and use the color cartridge by itself. Has any come up with a workaround or solution to use a re-filled cartridge?
