Thanks Gadget. I should never have said I was having great fun - kiss of death!
Yes, I came to the conclusion that it was my ink cartridge - although, this time it just suddenly went green! It usually gives me a bit of warning by going all the colours of the rainbow for a while!
So, I changed the cartridge and then the printer started going 'clunk' and I've had no luck since! How on earth do I 'clean the head'? (I take it you don't mean I have to grab the shampoo and wash my hair!!

) Sorry, I'm PC challenged.
You're right about the cost - still a lot better than £10, if only I could get the damn printer to play ball!!
I should probably just switch it all off, go outside and scream, and try again later!!
