I think this has something to do with the chip that is on the cartridge. If the chip is not reset properly, than this can happen. We have this problem occasionaly with our remans, and will usually just change out the toner, and then they probably fust replace the chip. You should be able to press the "Go" button to print, but if this is happening several times a day, I am sure it can be quite annoying. Who are you getting your remans from? They would probably exchange it for you.
Have a nice day today, and a better day tomorrow!!!
