Right, i have just had a Samsung SCX - 4521F printer delivered for my little office, yesterday i shut the computer down and disconnected it so i could move the filing cabinet it was sat on, now it says scanner locked in the display and wont work, the CD user manual wont work either, and theres no instruction book, apparently there is a switch on the thing to do with transit? has anyone got one or got any ideas where the switch is? i have searched everywhere!! Thanks!
