These printers monitor the cartridges and dont like you using aftermarket ie non Lexmark, or not made by lexmark cartridges. So Im wondering If you have tried 2 x brand spanking new OEM Lexmark cartridges, or if you are trying to use cheaper from net remanufactured or "for use in lexmark" cartridges. If this is the case then this is your problem and also very common.
Are you using a photo cartridge and a normal color one?
These I beleive can not be mixed in different slots.
- Photo cartridges you will only need one installed on the left side.
- Normal ink you will need two installed (Black on left and color on right) .
Also Lexmark themselves have a couple of documents on this issue, here
But these efforts will all be useless unless you are using Brand New Original Equipment Manufactured (OEM) Cartridges. This I see day in and day out, I get a lot of people tell me they are using original when they are not in fact, You will know by the price and lexmark carts do not state "for use in"
I dont think it is a problem with the printer, if you are using both brand new OEM cartridges then the firmware fix from lexmark should solve or you are trying to mix Photo type and normal type carts.
But these days ink jet printers are non repairable (well too costly and uneconomical to repair) throw away items, the expense is in the inks and manufactures vertually give away the printers so you will buy their inks, and lexmarks are designed not to like refill and aftermarket inks as are most modern inkjets.
Hope this helps, please let me know if you are using real ink and have tried the firmware fix and still are having issues, but all i probally end up telling you is buy another and welcome to our disposable way of life;)
