Be sure all of the chips are the same version. I';ve had this happen when I mix different version numbers.

I have taken out the MIS cartridges I was using and replaced with a spare complete set from MIS to run colour printing. The machine is showing orange printer empty lights and the printer dialogue is now saying it does not recognise the cartridges apart from black. I swapped the chips from a couple of the carts with those from the ones which had been working but still the dialogue says the carts are not recognised. I'm thinking this may be down to a firmware update I wasn't aware of. Has anyone else had this issue? Anyone know if it's possible to reset the printer firmware to the original factory setting?
I have uninstalled the printer driver and re-installed from disc, without connecting to the internet to get an original driver, but this has not solved the problem. I need to have some colour prints done by Monday and can't get to anywhere that sells original carts and I'd rather not throw out my complete set of MIS carts, ink, B&W ink and spare carts.
