How do I change email setting on my scanner?

How do I change my scanner's file type setting on my HP Photosmart c3140?

• I keep searching their site and the help window on my scanner's window, but all it keeps telling me is that i can add file types to the list, thats what i want to do, but nothing is directing me on how to do it, and I'm getting frustrated. It scans as a jpeg, bitmap, gif, or tif, and says i can add more to the list, i wanna add PNG to the list, and i know i can because i had it like that before but i had to reinstall it recently. Any help on how to change that setting?

• Answer:

  After you've scanned it and go to save it, can you save it as a PNG from the drop down list? * Here's another idea. When I save a picture I see now it's only offerering a choice of jpeg or bitmap. I opened Publisher and inserted the picture which I'd already saved previously. Then I right clicked on "save as picture". The option of PNG came up. It's longwinded but it might help.
