Re: samsung scx4216

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.

Fixing unit error. Turn off and unplug the printer, and then contact the store where you purchased the printer or your service representative. When contacting the service representative, inform them of...

The problem is in your fixing unit
the reasons may be
(i)The thermistor has an open circuit or a short circuit.
(ii) he heater has an open circuit.The thermal fuse has blown.
(iii)The power supply PCB has a fault.
(iv)The engine controller PCB has a fault.

Check the following,
- Check the connector of the fixing film unit.If found no problems,
-Replace the fixing film unit.Not solved?
- Replace the power supply PCB.Still having problem?
- Replace the engine controller PCB.
and that's it

SAMSUNG Multifuction Printer-''Open Heat Error'' (SumsangSCX-4215F)

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.

"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.
