Yup, there is a way, but it takes time. Write a loop (in Postscript) that
increments a variable. For each run thru the loop, call the checkpassword
(I'm not sure this is the real name for that function -- check your printer
manual) function to see if this is the correct password. If found, do an
exitserver using the correct password (which you just found) and reset
it to 0.

As I said, there are over 4 billion possible passwords, so this is likely
to take some time.

Once you have set the password, WRITE IT DOWN!
