I have a Lexmark X83 printer. It has both color and black & white cartridges. I recently put in a new black & white cartridge, but the printer will not recognize the new cartridge. It is as if it doesn't know that a new one has been put in. Still prints in color, but any attempt to print in black & white gives message "black ink is low." Any suggestions as to how to solve this? Thanks much in advance.
