Invalid printer catridge reading

Samsung strongly recommended original supplies as it has programmed sensor/fuse in it,

Well, eventually I worked it out: The "contacts" are four square fields to the left on on the backside of the cartridge. And it works instantly. (I read somewhere that it needs to be fully transparent tape. The 'blurry' tape leads electricity and doesn't work.)

the best thing to do is buy the original toner. how ever if u really can't then try changing the blue colored one

replace chip on the cartridge

The cartridge is original? If not replace the chip on the cartridge or buy original cartridge

First, Lexmark does not now or ever support the use of a third party cartridge or a refilled cartridge ink cartridge even if it is a Lexmark cartridge. Lexmark considers this to product tampering.

That said, please get a new Lexmark cartridge that is designed for your model of printer and see if it works. If you still get the failure, use a lint free slightly dampend cloth to wipe the contacts where the new cartridge goes. If that does not work, call Lexmark Technical support and see if there is still any warranty left on the printer.

Worst comes to worst, you can just replace the printer given the cost of ink jet printers nowadays.

Don

The Error is incorrect or Invalid .
The error invalid comes if the printer and cartridge does not belong to the same region.

Try this

Turn the printer off hold down the menu button turn the printer back on while continuing to hold down the the menu, when you get a green light your ready to print

Strongly suggest you use canon cartridges - have found all others to be rubbish

I've had the same problem over the years and somewhere along the way came across this simple fix: when you get the "invalid ink cartridge" message turn the printer off, wait 10 seconds, turn it back on, when the screen switches from "please wait" back to "invalid ink cartridge" tap the pause button. this will somehow reset the printer and you should be good to go.
