That's a ink loader error, due to the 8200 ink stick; to fix it:
- Power down the printer.
- Hold the back button and the info button at the same time, without letting go, power up the printer.
- Keep holding down the buttons until the XEROX logo comes fully to the center of the screen, keep holding for 2 more seconds, then let go. I'll take about a minute or two for the Diagnostic screen to come up, the display will turn blank and black.
- When the Diagnostic screen comes up go to down to the Function or Exercise option, there will be an option that says "clear ISC faults" it'll ask you to press OK to confirm, after you do then you will exit Diagnostics and the printer will reboot.
- It should be fine until it happens again. Until all the 8200 ink is gone you will probably be doing this a few more times. Also make sure the 8200 ink is not jammed inside the ink loader, if it is then you have to un-jam it some how.
