Flak999....Whilst I can't help you with your main query, I did check your link and looked up my own Lexmark inks. It was 'raised eyebrows' at the prices they charge for originals. I can see why you would be drawn to the less expensive versions.
I get my original Lexmarks through Amazon in the UK (via one of its online 'shops') at considerably less than the prices shown in your link.I have gone down the route of buying so-called 'compatible' alternate brands and wasn't very happy with the results.
I would direct you to consider having a look at the Amazon UK website where you may be pleasantly surprised at the costs.
I hope your other problem soon gets resolved.
