Is there a question you wish to ask, or is this meant as a tip/trick. If the latter is the situation, you should use the Post a Tip or Trick instead of what you used.

I do not recommend such post, too. If it's going to be as unclear as this post, what's the use?

Ι΄m sorry ! This is a litle code where i use. Yes is a question and i looking to find how to work if the scaner device has autosystem for scan.

Not a question. Not clear. What are those "pages", "images", etc. Why?

Based on the question in the title, just put your code in a loop. Ask the user if they want to scan more and then do it again and again. If your code is working putting it into a loop should be easy.

WIA does not support features of some scanners like autoscanning. I expect you will find that you will be stuck with the most basic functionality available, unless you can tell the user to start an 'autoscan' mode where you write your own loop, as someone suggested.

It's working
You need to add the Reference (Microsoft Windows Image Acquisition Library) or WIA.
in the code replace powerImage to PIctureBox
that's it
I hope it will work for you

Public Shared Function ScanDocs() As Image
        Dim CD As New WIA.CommonDialog
        Dim F As WIA.ImageFile = CD.ShowAcquireImage(WIA.WiaDeviceType.ScannerDeviceType)
' set your own folder
        Dim strTempfile = "Your Folder Here" & Format(Now, "MMddyyyyhhmmssms") & (1000 * Rnd()).ToString & ".tmp"
        Dim pic As New PictureBox

        F.SaveFile(strTempfile)
        pic.Image = New Bitmap(strTempfile)
        Return pic.Image
    End Function
