When the Message Does Not Disappear
When the message that indicates a paper jam occurring inside the top cover does not 
disappear even after the jammed paper is removed, this indicates that the jammed paper 
still remains in the fixing unit. Remove the fixing unit using the following procedure to 
remove the jammed paper.
The fixing unit and its surroundings inside the printer are hot during use. Make sure the fixing unit is completely cool before 
removing the jammed paper. Touching the fixing unit when it is still hot may result in burns.
When you remove the fixing unit, you have to turn the main power switch OFF. 
Sending or receiving documents cannot be done when the main power switch is OFF or the power cord is disconnected.
If the main power switch is turned OFF, all jobs waiting in the print queue will be erased.
Documents received into memory and documents stored for delayed send will be retained for approximately 60 minutes 
after the power cord has been disconnected.
