| that code points to the fuser, but many times this code will pop up when power goes out or possibly a surge. press and hold the "function" button while plugging in. that should get you in maintenance mode. then press "91" and you should see "parameter init". when that clears press "99" to exit maint. mode. when you see screen say "please wait", unplug m/c, then power back on. if that doesn't clear it tyr getting into maint. mode again and instead of using "91" try "01" and follow same procedures. if that doesn't do it, then you most likely have a hard failure in fuser area.
