Dear
The open heat error due to the temp. of fusser has not attained within predefined time due to either failure of heater lamp(rare),failure of thermostat(frequent),failure of fusser assembly(melt).
In first two case the parts can replaced(may be reset thermostat by knocking on hard surface) but incase of fuser melts then both fusser assy. and smps to be replaced confirm whether the printer power from DG set.
Thanks.

This is Laser Scanner Unit error and this is probably cause if the polygon motor in the LSU does not rotate.The LSU's laser beam is functioning properly.You can try unplugging the machine for 3 minutes and plugging back in before you do anything else.If this does not fix it you will need to have it serviced by samsung.
