Re: Engine Fuser Low Heat Error

HI, Yes it definitly sounds like your fuser is not getting to the proper temp. I would call Samsung and have this printer repaired or sent back. If you purchased it recently your warranty should be available. Hope this helps!! Thanks

Low Heat error...Cycle Power Samsung ML-2855ND printer

There is a problem with the fuser unit. This unit fuses the toner powder to the paper and if it is not hot enough the toner powder won't bond onto the paper.
Try removing the fuser unit, check the two fuser power spring contacts, and insert it back in the printer. If the error still occurs then you may need a new fuser unit.
You may need to get the printer checked out by a technician.

Got message engine fusion low heat error I replaced the fusion unit in early 2010, do I need to replace it again?

Low heat means the the fuser is not reaching operating temperature. The fuser may be bad, it could also mean that your voltages from the power supply are low. But , yes it is probably the fuser. The one you replaced in 2010, should have warranty, depending on where you purchased it.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response. Happy New Year!

Thanks, Joe

Engine Fuser Low Heat Error

What this means is that the fuser is not reaching operating temperature. The most common reason for this failure is the xenon lamp inside the heat roller of the fuser has burned out. You can verify this by checking for continuity between the two contacts that connect to the lamp with an Ohm meter or digital multi meter.

If the continuity is good, the second most common reason for failure would be the LVPS, or low voltage power supply.

And last, although by far the least common reason for this error is the main logic board.

Have you checked to see if the unit is under warranty? If so, this would be a covered repair.

The part number for the fuser is listed below. Depending on your location and electrical system ( 110 or 220 )

ELA UNIT-FUSER 230V part number :JC96-03239A for use with 230V
ELA UNIT-FUSER 110V part number :JC96-03239B for use with 110V

Other then samsung, you can try a google search, and also an ebay search for the part number and find the best price for the item.

Good luck,

"Low Heat Error"

Thats probably the best way to solve the solution. Sometimes if there is a thermistor that is causing the problem that can be serviceable in the fuser unit, that can be replaced instead of purchasing a whole new fuser assembly. It's less expensive replacing the thermistor.

I have just replaced cartridges and am now getting fuser low heat error.

Yes, either the lamp in the fuser is burnt, the thermistor (heat sensor) on the fuser is burnt, or the low voltage power supply is not providing enough voltage to the fuser lamp. Your safest bet is to replace the fuser.

BUT!!!! The printer itself is let than $150 new with warranty, so if you like this printer I would buy a new one. A fuser will be between $90 and $150 and could be difficult to replace. If you get a service person to replace it you could expect two hours of labour at least which will be about the price of a new printer.

Engine Fuser Low Heat Error

Basically the error message is telling you the printer cannot keep the fuser temperature at the proper temperature (too low). It could be a lot of things but typically it is due to a fuser assembly gone bad.

Fuser Error 50.1 Fuser is hot. What is a fuser?

I think the fuser is in your **** part. This problem can be corrected by sitting in a tub of salt water. Make sure the printer is plugged in and is powered on. Is the display lit? If it is place the printer in the tub of water you are sitting in. You sould now be able to realize nobody cares and it no longer matters
