I forget the password of Print Server. How can I reset the password back to default (blank) ?

Reset password to default: The way to reset password to default is :
1. Run Bi-Admin-> Select and click Print Server.
2. If display Password dialog, enter [+_*] in password dialog (totally 5 characters) and then press ENTER.
3. Click "InitDevice" on main menu bar-> select "Restore factory default"
4. If display Password dialog, enter [+_*] in password dialog (totally 5 characters) and then press ENTER.
5. The "Restore factory default" procedure will begin.
6. Close Bi-Admin and restart it. The password will be reset to be blank.

Note: All pre-settings of Print Server will become to default while you do "Restore factory default", so you need re-configure Print Server after do "Restore factory default".
