Hi all, I haven't use my iX6550 for a while and now when I switch it on, it kind of tries to go through it's start-up procedure, then just gives me some alternating flashing 'Stop' and 'Power' light rubbish - 8 flashes (each laight), then a pause, then it repeats then sequence. I've tried a few different switch off and switch on while holding the Stop button and pushing it twice / five times etc. but it is still doing the same thing. Also, when I open the top cover, the ink cartridges don't proceed to the position needed to make replacements - Mainboard maybe? Any help much appreciated. Cheers, Keep well.
