Here is a way to get past the hated Waste Toner Full message which accompanies
a blown fuse:

1.  Turn printer off and wait 30 seconds.
2.  Press gray Select and blue Printer Setup buttons at the same time and
    hold.
3.  Turn on printer.
4.  Release buttons when printer beeps. The LCD display should read PCU DIAG
MODE.
5.  Press and hold the two gray buttons labelled Up and Previous until the LCD
    display changes to read Fuse Flag Reset.
6.  Release the buttons.
7.  Turn printer off.
8.  Wait 10 seconds.
9.  Turn printer on and try printing.
