hey guys. ive just installed a HP scanjet 5530 to my emac but when i go to scan it says 'cannot find default scanner'. I cannot seem to figure out the problem of how to set it as default or whether its just broken. The system has picked up on it but its just not working. i also tried it on a powerbook and it works with that. i am truly baffled!! help would be a huge huge.... uhhh help! thanks.
