- Low heat error – Low temperature error (error code 62)
- Open fuser error (error code 60)
This is main components of fuser unit:
I. How to solve fuser error Samsung ML-2251N.
When ever fuser unit occurs problems, printing device does not print and all the LEDs blinking. Gear of the fuser does not work & breaks away melt away. When ever printing, motor breaks away from its place due to defective fuser gear.
Now, you need to perform the below steps to test. Where is the error? and then meliorate issues
1. Test thermostat, could possibly be AC wire and Heat Lamp is open.After test thermostat, When it is open replace the fuser & try print to test
2. Check the thermistor sensor. Any time location of the thermistor sensor device is located deep in the sponge, renew thermistor sensor & then print check pages. Whenever still error you actually must change the fuser unit.
3. Test the halogen lamp. Test whenever the circuit of overheat mode works properly. And then renew halogen lamp
4. Test the overheat circuit works properly by DCU with DCU mode is code 10
6. The fuser end of life. Regenerate fuser unit
Anytime anyone could possibly not finding error located. You may perhaps be test by DCU with DCU mode is code 60, 62 or 68 & then refer to underneath:
II. How to fix(restore) low heat error Samsung ML-2251N?
Low heat error is error occur manifestation when ever the temperature of the unit lower than temperature conventional.
The phenomenon of demonstrated Samsung ML-2251N printing device occur error "Low heat error" is:
- The inkjet printer does not print, the Online/Error LED (red) & the Toner Obtain LED are flashing 4 second/ one times.
- The low heat error on the Samsung ML-2251N printing device is related to the fusing assembly. Below is a list of the most common complications that may perhaps cause a low heat error.
1. Cycle the turned.Anytime the printer checks the fuser at the wrong time like during a sudden turned outage, it may possibly look for an inaccurate reading causing this error. Sometimes a simple cycle turned will resolve the issue.
2. Check your own switched source.
Plugged switched cable of printing device direct into a wall outlet. Too many devices plugged into the same circuit may possibly also cause a turned struggle between devices & lead to this issue.
3. Follow the diagnostics mode underneath and test the temperature of the unit any time it should be hot.
- Move out the fuser unit (review How to remove fuser unit Samsung ML-2251N) & test for continuity across the thermostat & hot roller assembly.
- Test the overall condition of the fuser unit. As soon as the hot roller looks extremely worn, the gears are wearing out, or the pressure roller has wrinkles and also tears in it, you should replace the fuser unit Samsung ML-2251N.
4. Remove the thermistor on the fuser unit & clean it off & yield sure it is secure against the hot roller.
Debris or when ever it is positioned to fair away from the hot roller may perhaps cause low heat complications. The thermistor is very sensitive and it doesn’t take much to throw it off.
5. The contacts between the electrodes on the sides of the hot roller aren’t making a good connection.
Because this is a metal on metal contact & electricity is running through it, it tends to look for corrosion in this area. Take an emery board to the surfaces and try to scratch off some of this build up.
6. Anytime still error than replace the fuser unit.
III. How to fix(repair) Open fuser error Samsung ML-2251N?
The phenomenon of demonstrated Samsung ML-2251N printer occur error "Open fuser error" is: The printing device does not print, the Online/Error LED (red) & the Toner Get LED are turned on & off repeatedly 1 second/ one times.
The Open fuser error on these printers is caused by An open-circuit in the fusing assembly.
This error to be one of the more common complications of Samsung ML-2251N printers. If they over heat, one or both of the thermostats above the fusing assembly will probably open. As the fusing unit cools back down the thermostat is supposed to close, if the printer is power back on it could operation as normal. However, it does not operation properly. The unit cools back down but the thermostat fails to close back up. In this post, i document you solve hassle without renew fuser unit
1. Remove fuser unit out of frame.
2. Move out the fusing assembly & thermostat
3. Test the thermostat, is the continuity across the two parts?.
- If it has continuity then that’s not the problems.
- Conversely, measure across the individual thermostats to obtain which one is open. While people isolate the issues child take a can of air & hold it upside down
Now render the front of the thermostat, open in that may be depressed, blowing of extremely cold air then try check the thermostat for continuity once again. Anytime it has continuity now, then reinstall it & put the fuser back in the printing device. While the fuser rollers haven’t melted together you actually must have a working printing device again.
4. After mend thermostat, the printing device still error then the problems can be in halogen lamp or connection hassle.
The thermistor the Fuser runs on AC switched so you actually must have continuity across the halogen lamp and thermostat. Pretty much a connect path going into and out of the fuser unit. Anytime you’re getting an Open fuser error then something in the fuser circuitry is open. It’s up to anyone to find it. Now while anyone don’t feel like doing all this checking then your company's next step is to change the fuser unit.
5. When you actually have the fuser out, you must test the condition of the unit. Look for scratches in the hot roller surface where the thermistor and pick fingers may have worn away the surface. Test for a warped and also wrinkled surface on the pressure roller. Finally check the gears out. Look for gear dust & worn down gear teeth.If there is a problem may not be solve, people must reaplace Change Pressure Roller & heat rolle
