Thank you for all your help. We did everything as you suggested and then realised
that we would also need to purchase a power supply 9.5V. Previously the scanner received
its power via the printer it was attached to and of course once it was no longer
attached would obviously need its own power. We are feeling rather foolish but still
think we would have required the other information you gave us. Will let you know
if the power source is all we needed but won't be able to get it for a few days.
Will be in touch with the info but thank you very much.
