Replacing the Fuser Unit (3041/3042)
When the time to replace the fuser unit is reached, the message FUSER UNIT/END OF LIFE appears.
Printing can continue even after this message appears; however, since the print quality is reduced, the
fuser unit should be replaced immediately.
1. Turn off the printer.
Note:
There are extremely hot parts within the machine. Before replacing the fuser unit, wait about
40 minutes after turning off the machine, and then check that the fusing section has reached room
temperature, otherwise, you may get burnt.
2. Pull the lever, and then open the right side cover.
Note:
Before opening the right side cover, fold up Tray 1.
3. Open the eject cover.
