hello everyone

this machine won't print from tray 1 - someone has set "tray 1 config: Paper Size" to CUSTOM (rather than 'cassette size') as per the attachment

OKI C911.pdf

i'm assuming one has to enter ADMIN SETUP to change this back to 'cassette size' but the factory admin password (aaaaaa) has been changed - can anyone tell me how to reset the admin password and confirm how to change tray 1 back to 'cassette size'

thanks in advance!
