1600n Open Heat Error
Our printer recently stopped working altogether, and the error message that it gave me was 'Open Heat Error'. We just turned it off and left it alone for a while, but would like to get it going again. I went through the printer troubleshooting page and it directed me to talk to support, but the warranty for our service tag has expired, so I was unable to do so.
Has anyone gotten this error before? Does anyone know what causes it/how to fix it? I'd appreciate any input I can get. Thank you!

This is most commonly caused by a failure of the Fuser unit.
However, in rare circumstances, this can be caused by the Fuser Control section of the SMPS, or the fuser temperature monitoring circuit on the Main Board.
There is a closed control loop:
1. AC voltage is supplied to the Heat Lamp in the Fuser from the Fuser Control section of the SMPS
2. The temperature of the fuser heat is monitored by a thermistor (mounted on the Fuser) connected to the Main Board.
3. The Main Board determines if the fuser temp is too low, correct, or too high and signals the Fuser Control to increase, maintain, or decrease the AC voltage to the Fuser
