My printer just finished cycling through a "power interuption" likke mode. Now there is the error code which does not leave.
What is this and how can I make it go away?
Go to Solution.
It means: 91-547-00 Printhead 1 Reservoir Heater Too Hot
And if a reboot doesn't fix it (I'm sure i can safely assume you did that) then it would require a service tech to fix as it would be a hardware failure.
