Dynamsoft TWAIN Products

Hi,

I'm using Dynamsoft Web Twain ActiveX version 5.1.1 on a web application. Trying to use ADF and scan multiple pages at once. Everything seems working with "Kodak i55" and "HP Office Jet J4580 ALL-in-One" scanners but there is a problem with "Cannon P-150" model. It gets all document pages from ADF and scans all of them however, component displays only the first page.

When try the scanner (Cannon) on your Demo page (version 5.2) and works perfectly. Is this a version issue?

Here is the code (Javascript) that I use:

function AcquireImage() {
var i;
try {

with (document.all) {
frmScan.DynamicWebTwain1.SelectSourceByIndex(source.selectedIndex);
frmScan.DynamicWebTwain1.IfShowUI = ShowUI.checked;

frmScan.DynamicWebTwain1.SelectSource();
frmScan.DynamicWebTwain1.OpenSource();

frmScan.DynamicWebTwain1.PixelType = 1; //0:Black-White, 1:Gray scale 2:RGB image
frmScan.DynamicWebTwain1.Resolution = 200; //Image resolution

frmScan.DynamicWebTwain1.IfDisableSourceAfterAcquire = true;

if (ADF.checked) {
frmScan.DynamicWebTwain1.XferCount = -1;
frmScan.DynamicWebTwain1.IfAutoFeed = true;
frmScan.DynamicWebTwain1.IfFeederEnabled = true;
}

frmScan.DynamicWebTwain1.AcquireImage();

}
}
catch (err) {
alert("hata oluştu");
}
}

Hi yilmazumit,

It is not a version case. For information on why you only get the first page into the control, please refer to:
http://kb.dynamsoft.com/questions/87/Wh ... ugh+ADF%3F

Also, if you want to scan multiple images into the control, you need to set the value of MaxImagesInBuffer to the maximum number of images that can be held in buffer. For more info, please refer to:

If the problem persists, you can contact our support team via LiveHelp to have a GoToMeeting session.
