How to add more pages while scanning with Umax...

Scan a page, after that send it/save it, now does it display the option to scan another page or to finish it. If it does, select scan another page and proceed. If not the s/w supplied with the scanner does not support this function.

In any case you can use pdf creating softwares like Adobe acrobat (not acrobat reader) to achieve the same result. These softwares support scanning function as as well as you can subsequently insert/ remove pages from a pdf file.
