Lexmark c524 eror black cartridge missing or empty

when your black cartridge goes empty , the printer automatically goes into the reserve mode where it mix up the colors in the color cartridge to produce black color

The Lexmark X2600 requires both cartridges to have ink in them to continue printing, even if your printing in "black and white". To print true black, you actually use some of the color ink. , Leaving the color cartridge empty or dry isn't good for the printer. It can lead to poor print quality issues.

Make sure your black cartridge is not very low on ink or empty. Otherwise, replace it with new genuine cartridges.
It could be a communication problem between your black cartridge and your printer. Try to re-seat the black cartridge into the printer.
It could also be a short in your black cartridge. Try to insert a different known working black cartridge. Better yet, replace it with a new genuine Lexmark cartridge.
If the problem continues, please contact Lexmark Technical Support Center for additional assistance.

Hello

need more clarificaton!!!!

This can be one out of two things. Either a faulty cartridge, or the cartridge holder. If you still have the old cartridge, insert that one. If now it only displays 'Cartridge Empty', it means that the printer can see the cartridge, and it's your new cartridge that is faulty. If it's still showing Cartridge Missing, it's most likely your printer that is faulty. In either case, you should contact Lexmark Technical Support and they'll provide you with a solution. 

You can also try cleaning the contacts in your cartridge Holder with a dry cloth.
