Scaner setup question

[stan]

I am trying to set up my HP C2520A scanner on 7.1 san-find-scanner finds it
at /dev/pass0, byt that device is only acessible to root:

crw-------  1 root  operator    0, 104 Dec 30 18:10 /dev/pass0

Now obviously I could change this, but i am wondering what the "correct"
way to allow ordinary users to access tis device is?

zero, they had no way to indicate successful termination of their C
