Samsung says you should send it in for service, and lists service locations. They also say the fuser typically dies after 50,000 pages -- 100 reams, which doesn't seem like -that- much.

You may be able to call a service center and see if they can help.

I did a search and found someone purporting to sell a service manual for $10; I don't know whether this person is credible and legitimate and legal.

You may try to see how much the service manual costs through Samsung itself.

Open heat error


this means the fuser isnt heating up or sometimes that the printer doesnt sense it heating up, to work out which one applys to you leave it turned on for a few minutes and feel the rear vent, if it is warm then the fuser is good and the sensor is faulty, if its not then the fuser lamp needs replacing, either isnt usually a "user servicable part". get the best idea of the exact issue and approach a repair shop or samsung service provider. if its under warranty contact samsung. if its not get a quote if its more than you think its worth sell the printer with this fault described.

Open heat error, you have a fuser problem, replace fuser. Fuser consists of Upperheat roller, lower heat roller, exit claws/rollers, and a heating circuit with a lamp, thermal temp sensor (thermistor) and a thermal fuse/cutout.

You could measuring fuser removed from machine, checking lamp etc for open circuit, thermistor should be neither short or open circuit.

These days we dont, we just change assembly due to it being a common constantly wearing part, and if for example I pull it apart, fix the lamp, put it together then soon enough I will need to pull it apart again to fix worn roller etc.

I could give you the part number ... JC81-01690A but dont use it, cause that part is for 220volt cause thats what we use in Oz, so contact Samsung and ask for dealer in your country who can supply you.

P.S. Fuser is the Hot bit (180 deg c) at back near paper exit that bonds(melts) the print into the paper.
