Question about Samsung SCX 4521F All-In-One Laser Printer
To clear the "low heat" error, turn the machine off and unplug it from the wall. Wait a couple seconds then plug it back in and turn it on. Hopefully the error will clear and you can resume normal operation.
If the error still occurs, you'll have to call a service technician to either fix or replace your printer's fusing unit.

My 3175FW has same problem. None of the quick fixes worked. I took it to a service company. They tried a fusion unit, but that didn't fix it. Their estimate is that the printer needs a new power supply -- $300 before labor. Not worth it. Can't believe I spent that much money for a top quality printer (so I thought) and it lasted less than 2 years. Never again, Samsung.
