Fuser temp. OKI B2500MFP

hollo,you need to replace the fuser unite.try truneing it off and back on and if it dose not clear you need to place a service call.

Don't Worry nothing is damaged.
The message usually shows when the electricity is off
it is easy! u just have to call to yr local service (Greece: +302310531334) and they will give u instructions to erase this message from the memory so as u can work again with yr oki.
THe instructions have to do with the menu on the oki display.
