Error #1203

Error #1203 is a message error caused by either a communication failure between one of the printheads (cartridges) and the All-In-One (AIO), or by a shorted printheads.
In clearing up this error clean the contacts and look for obstructions around the printer head and cartridge.
You also should update your computer and printer software with the wizard available at the Lexmark site:
Many times the computer gets updated, or the printer software, and if not both them then both don't have the same information, and will cause an error.
