How do you know its a lamp error?. if it is the scanner lamp its located under the glass. And you replace the whole module not just the lamp, or is it the fuser lamp, you just replace the whole fuser section which is the Hot part.

To reset fuser unit you need change the 60mA/250V fuse,located in the fuser unit contact house (a little green diode).

Remove the fuser unit and verify the fuser heater lamp continuity and the thermofuse continuity.To reset the trouble code please tell me the copier model.

you need to get a small pico fuse(small green resistor like part on wire harness in fuser. or if your fast you can remove the fuse and short the wires turn on the machine then count to 10 and unshort them. fuser will reset. this is the only way or get a new fuser (too spendy) write me back if you need help.

This is a fuser related code.
To reset the code, please do the following
1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch Trouble Reset.
4. Check to make sure that OK is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after
and check if the machine starts correctly.
