Xequte Good morning! I have some problems with the WIA and TWAIN scanning. It was discussed at the forum on "http://www.imageen.com/ieforum/topic.asp?TOPIC_ID=470." When an error occurs during scanning, using the drive "Twain," he did not return the pages already scanned, which does not occur with "Wia". When Twain returns a page is just a page in black and white, the other page is lost! Also occurs with Twain, who during scanning, for some reason the scan is interrupted, and not to identify the "Twain driver" or "scanner" or "ImageEn."
Also with Twain, even allowing duplex capability, the scanner only returns me the "back of the sheet scanned."

Page Return TWain:



I use the Kodak i1220 scanner with the drive version 3.33, ImageEn Version 4.1.0, Delphi 7, Win7 64Bit, 4GB Memory and Core i5.

The ImageEn me list three options kodak scanner, but these three, the last is the WIA, and do not know why the number 2 is identified because he is not WIA.

Forgive me so many posts, but am new to ImageEn, and so when I post the manual does not provide me with the answers.

Please, what could be wrong?

In my tests (with i1120) the scanner acquires both sides of the sheet.
I used this code:

  imageenmview1.MIO.SelectAcquireSource();
  imageenmview1.MIO.TwainParams.VisibleDialog := false;
  imageenmview1.MIO.TwainParams.DuplexEnabled := true;
  imageenmview1.MIO.Acquire;


Anyway I am going to send you an updated version (to your private email) in case you have a buggy version.
