UJF-6042 MKII - Error 729 HHEATER HIGH TEMP

[Landrik]

Not sure what to do about this error and haven't found anything in my searches for a solution. The maint manual says "The heater temperature exceeded the high temperature threshold" with the suggestion "Check the voltage switching SW on the side of the device". Which is still set at 110V so..not very helpful. Anyone have any ideas?

Thanks

Might have a bad circulation pump.

Might have a bad circulation pump.

Thanks that gave me a place to start. When I opened the back I saw a lot of air in the tubing. The operator didn't get the cap on tight during a water fill leaking pink everywhere and I'm wondering if we got a lot of air in the system then. Syringed out prob 60cc of air and got prime on the pump again and we're back to printing. Thanks again.

Yup, might have lost prime on the pump and it's not circulating.
