I have a Ricoh IS430+ scanner which used to work but since i've re-installed it just sits there flashing its lights at me as though jammed. I have tried various different drivers but none work so i think it may be hardware,although everything is in the right place inside and there aren't any jams i can see. Does anyone know of this problem, or even know of a place where i can get a copy of the manual,which(typically)i cant find!
