Konica Minolta C650i - FS539SD

[Kenny]

H guys,

currently got a issue with an FS539SD with error C-1184

we have tried to replace the M12 motor + PS28 but still persisting with code, the side tray doesnt lift up/down then throw the code,

does anyone have any suggestions

Guess you tried moving the tray manually down by turning the drive with your hands and see if it comes up?

It's possible that the stepper-miotor driver IC on the finisher board or some harness is faulty.
