heater error message

[niksagkram]

Hi. We have an older SC-540 with the HU-540 heater retro fitted. Printer works great, but I've recently started getting error messages on the heater control. The error message is "UUUU". I cannot find a listing of the HU-540 error messages anywhere. Anybody know what this might be?

Thanks,
Mark

I have an old SC-500 that was retrofitted with a Roland heater unit.
Haven't chucked it in the garbage bin yet.
Looks like the heater unit is the same kind.

If you need to replace yours let me know.

Looks like a thermistor error.

Thanks. I got rid of the error code (not sure how ) but now the upper number (red) seems to be in fahrenheit instead of celcius. Right now my set temp is 40, but the red number above it, is reading 112!

At least it seems to be working now, sort of. Think I'll go search out a service manual for it, if one is available. Thanks for all your help.
