I have a C350 that won't let me enter it's Admin mode. When attempting
access via the web interface, it acknowledges I'm entering the right
password (by returning "login failed" instead of "wrong password"),
but it won't log me in. When attempting access via the copier's LCD
panel, it just beeps at me when I press the button. According to
documentation, it's behaviour is consistent with what it should be
doing when it prints a job. But it's doing all this when it's not
doing anything. Power cycling (turning it on and off) doesn't help.
What might I try to fix it? Is it possible to flash it's firmware?
