Hello I have recently installed new ink cartridges in my printer however the black does not seem to work and the colour prints fine. As far as im aware I have tried all of the troubleshooting steps that I can. Does any anybody have any ideas?

Thanks

Assuming you did remove the protective tape covering the nozzles, then you may need to coax the ink out a little. Although this is not an officially recognized procedure, I would take a paper towel, dampen it with water, and squeeze out all the water you can. Now fold it until it is about 3-4 inches square. Take the black cartridge and touch it to the paper towel for a couple of seconds. (Touch the rectangular chip to the towel). You should get some ink to flow into the towel. Move to a clean area and do it again. Maybe one more time, depending on how good it is flowing. Now, put it back in the printer and hopefully it will be happy.

Best of luck,
