Open Oestrus Error Cycle Power on the Samsung ML3051 / 3051ND Printer
Troubleshooting and Repair Tips for the Samsung ML-3051ND and ML-3051 Printer
The Open up Heat Error on these printers is caused by an open up-circuit in the fusing assembly, Dell / Samsung JC96-04387A / UG297 110V Complete Fuser Assy 
. I find this error to be i of the more mutual errors I discover on this model of machines. For some reason the fusers in the Xerox, Dell, and S amsung machines have a tendency to over heat. When they over heat, one or both of the thermostats on top of the fusing assembly will open. As the fusing unit of measurement cools back down the thermostat is supposed to close, thus when the machine is turned back on it will piece of work every bit normal. Unfortunately, that tends not to be the case. The unit cools dorsum down and the thermostat fails to close back upwardly. In this commodity, I'd like to talk about what you can do to effort to manually reset the thermostat to avoid fuser replacement.
Follow the instructions beneath to remove the fusing assembly and thermostat. Once you have the thermostat out test the continuity across the two parts. If it has continuity then that's not the problem. If it doesn't and then measure out across the individual thermostats to notice which ane is open. Once y'all accept isolated the problem child take a can of air and concur information technology upside down. At present give the front of the thermostat, open in that can be depressed, a shot of extremely cold air. This should pop it back into place. Test beyond the thermostat for continuity once again. If it has continuity now, then reinstall it and put the fuser dorsum in the auto and retest. If the fuser rollers haven't melted together you should take a working machine again.
If you have continuity across the thermostat and so y'all most likely have a lamp or connection problem. Except for the thermistor the Fuser runs on AC power so you should have continuity across the lamps and thermostat. Pretty much a straight path going into and out of the fusing assembly. If you're getting an Open Heat Error then something in the fuser circuitry is open up. It'due south upwards to yous to observe it. Now if you don't feel like doing all this testing then your next footstep is to supersede the fusing associates.
While you lot have the fuser out, yous should check the condition of the unit. Look for scratches in the hot roller where the thermistor and pick fingers could have worn away the surface. Cheque for a warped or wrinkled surface on the pressure roller. Finally check the gears out. Look for gear dust and worn down gear teeth. If you do get the machine functioning check the number of prints on information technology from printing a organisation data study. Wait to run across if information technology'due south effectually its estimated life of eighty,000 prints. If you observe any of these problems in the fusing unit from a visual inspection then it's probably time to replace.
