Thank you so so much for posting this! I've spent all day trying to figure out what it was. I thought the water cooling system broke down. Can't believe it was so simple. Your post really saved all of it. Very grateful!Just a update. If anyone has this problem. Check your ribbon connections. I fixed my problem because one the ribbons that are used for the ink were not seated properly. This error is usually caused by the ribbons shorting out. So check your ribbons in the head and mainboard
