1) If you try to use a single cartridge, it will tell you that you
cannot. This is because some magenta ink is always used to make the

removed any tape etc. Check your printer manual for exact install
instructions. If it still comes back with an error, it may be a bad
cartridge.

Wish I could do the opposite. I'm *STILL* sitting here with a dead i9100!
Canon have acknowledged they have received my invoice and that I will
receive my refund as soon as possible (whatever that means). In the
meantime, I've £360-worth of printer that's about as much use as a door stop
at the moment!

I know why you moved to the US now - you wanted to save money on your
computer stuff!

Blessed Be,
