I have a 942 all in one. I replaced the black cartridge and it will not align. It keeps telling me to take the tape off the cartridge. I did take it off and have even tried another cartridge and when I did take the tape off both of them there was sticky residue on the black case so I think there must be residue on the cartridge so I cleaned with alcohol and gauze. I even cleaned the head inside the printer but still not working. My black comes out pink. I also am thinking that this last box of cartridges I ordered from Dell must be damaged somehow. What else can I do to try and clear up this problem?
