Re: Cannot reset black cartridge on Espon DX 7450

It doesn't make much sense does it. I don't know anything about this printer. I don't know what cartridges cost but I'd be inclined to buy a new one to see if it works.
Your test does seem to rule out contacts. On my 2100P contacts were a huge problem - not just the contacts you can see but also the contacts on the other side of the contact block. Printers are a pain.
