Fault Code 93,597: An over range level sense error occurred in the Black Printhead reservoir.
Check for improperly installed ink stick
Power off for 30 minutes (unplugged)
Check if a leak internally allowed cross contamination (black in the magenta for example, this sort of thing almost always occurs if someone moves the printer without having it powered down and unplugged for at least 30 minutes)
Print head may need to be replaced.
