Hi Neil_H, sorry to hear that you are having issue with scanning to a specific folder. So I can better assist you, may I please have the operating system on your computer (WIndows XP,Vista, 7, 8-8.1 or Mac)? As for the ADF not feeding the paper properly, please try cleaning the rollers in the ADF with a lint free cloth lightly dampened with wate ( do not use alcohol or cleaners on the printer).
Please write back at your convenience and I will be happy to help.
Thank you.
