Fault Code 121.xx: Fuser Error Message

The error may be due to a poor voltage line (power strip or overloaded circuit).

1. Make sure the printer is plugged directly into a wall outlet.

2. Power Off the printer, wait for a few seconds and power it back On.
   
   Note: The above steps must be performed even if the printer has worked on the same power outlet in the past. Power strips and uninterrupted power supplies can cause a low amperage condition to occur within in the printer, which in turn may trigger a false fuser error.
   
   

3. If the problem persists, contact Support for additional assistance.
