No it doesn't print black with either old or new cartridge.
No message. It just stopped printing. The printer runs normally, paper, installation etc but just won't print in black.
Have cleaned Printhead but still no black.
Yes they are. Will only use authentic ones as I'm worried cheaper ones will damage the printer. I have 2 brand new cartridges, bought 2nd today, as I thought the 1st may be faulty, but neither work.
Many thanks for your help and advice. I had a feeling it would be something like that. Unfortunately no longer under warranty.
