Only 1 page scans after replacing printer

Postby drose » Wed Dec 10, 2008 4:08 pm

Loic,

I am seeing an odd issue with scanning from a Lexmark 6570 MFD.

Here's a summary:

Install Lexmark 6570 printer - able to scan multiple pages
Install second (replacement) Lexmark 6570 printer by plugging in printer and allowing plug and play to complete.
Printer object Lexmark 6500 series (copy 1) is created in Printers and Faxes
Set Lexmark 6500 series (copy 1) to default printer
Attempt to scan multiple pages - scans only 1 page.

I use the SelectScanner function to choose the TWAIN driver, but it still only scans 1 page after replacing the scanner. I am using the GdPicturePro library, but this seems more likely isolated to the TWAIN dlls (if the library at all). Any ideas?

Thanks for your help, as always.

Derek

Hi Derek,

Attempt to scan multiple pages - scans only 1 page.


Ok but how are you trying to do that ? a code snippet will be welcome...

I use the SelectScanner function to choose the TWAIN driver...


Are you talking about the TwainSelectSource() method ?


Maybe you are trying to use a WIA driver ? WIA can't control feeder through TWAIN. A solution is to use a real TWAIN driver.

I am using the standard example you give on the site here for scanning multiple pages to a tif. And you are right, I did mean the TwainSelectSource() method. But even when I choose the TWAIN driver from TwainSelectSource(), it scans only one page.

Hi,

Could you give me the link of the sample ? There is a lot samples about that on the site.

I went ahead and emailed you the code. I hope it is enough for you, if not let me know.

Here's the code:

Code: Select all
        long nImageCount = 0;
        int nTiffOriginal;
        int nImageID;

        if (axImaging1.TwainOpenDefaultSource() == true)
            {
                //Check that the TWAIN is ready to scan
                if (axImaging1.TwainGetState() == GdPicturePro5.TwainStatus.TWAIN_SOURCE_OPEN)
                {
                    //TWAIN settings for scanning and compressing
                    axImaging1.TwainSetErrorMessage(false);
                    axImaging1.TwainSetHideUI(true);

                    //While there is something to scan, scan it.
                    while (axImaging1.TwainAcquireToGdPictureImage(0) != 0)
                    {
                        axImaging1.TwainSelectFeeder(true);
                        nImageID = axImaging1.GetNativeImage();
                        nImageCount = nImageCount + 1;

                        //Create the file and show it in the viewer

Re: Only 1 page scans after replacing printer

Hi,

It is not really the sample I gave :)


I see one error in your code: you are calling the TwainSelectFeeder() method during your acquisition loop.
You must remove all the call to this method. Just add one call after axImaging1.TwainOpenDefaultSource()
Also, you are calling the ConvertTo1BPP() method before acquiring an image. Why ?

Here a cleaner version of your code. maybe your problem will be solved using this one.


Code: Select all
            long nImageCount = 0;
            int nTiffOriginal;
            int nImageID;

            if (axImaging1.TwainOpenDefaultSource() == true)
                {
                    //Check that the TWAIN is ready to scan
                    if (axImaging1.TwainGetState() == GdPicturePro5.TwainStatus.TWAIN_SOURCE_OPEN)
                    {
                        //TWAIN settings for scanning and compressing
                        axImaging1.TwainSelectFeeder(true);
                        axImaging1.TwainSetErrorMessage(false);
                        axImaging1.TwainSetHideUI(true);
                        axImaging1.TwainSetAutoFeed(true);
                        axImaging1.TwainSetAutoScan(true);
                        axImaging1.TwainSetCurrentResolution(300);
                        axImaging1.TwainSetCurrentPixelType(GdPicturePro5.TwainPixelType.TWPT_BW);
                        axImaging1.TwainSelectFeeder(true);
                        axImaging1.TwainSetCurrentBitDepth(1);
                        axImaging1.TwainSetIndicators(false);
                        axGdViewer1.SetZoomFitControl();

                        //While there is something to scan, scan it.
                        while (axImaging1.TwainAcquireToGdPictureImage(0) != 0)
                        {
                           
                            nImageID = axImaging1.GetNativeImage();
                            nImageCount = nImageCount + 1;

                            //Create the file and show it in the viewer
                            if (nImageCount == 1)
                            {
                                backgroundWorker1.ReportProgress(0);
                                nTiffOriginal = axImaging1.TiffCreateMultiPageFromGdPictureImage(nImageID);
                                axGdViewer1.DisplayFromGdPictureImage(nImageID);
                            }

                            //Add to the file and display it in the viewer
                            else
                            {
                                backgroundWorker1.ReportProgress(0);
                                axImaging1.TiffAppendPageFromGdPictureImage(nTiffOriginal, nImageID);
                                axGdViewer1.DisplayFromGdPictureImage(nImageID);
                                axImaging1.CloseImage(nImageID);
                            }
                        }

                        //.tif and TWAIN cleanup
                        axImaging1.TiffCloseNativeMultiPage();
                        axImaging1.SetNativeImage(nTiffOriginal);
                    }

                    //Displays a message if unable to open printer.
                    else
                    {
                        MessageBox.Show("Unable to open printer");
                    }
                }

                //Displays a message if unable to connect to the printer.
                else
                {
                    MessageBox.Show("Could not connect to printer");
                }

Loic,

I made the changes you suggested, but the problem persists. Is there anything else you can think of that may resolve this?

Thanks,

Derek

Hi Derek,

We ca try to see what is wrong.

1 - Download the last version from this site
2 - wrap your code with

Code: Select all
axImaging1.TwainLogStart ("c:\gdpicturelog.txt")


&

Code: Select all
axImaging1.TwainLogStop()


3 - Report here the content of the log.

I am using GDTWAIN version 4.4.0.0. To update the version would cause a lot of other components to have to be changed as well. But if you think a newer version may help, I can try that.

These are the 2 log files. The first is from the original scanner. The second is using the replacement scanner that scans only 1 page.

Original scanner:

Re: Only 1 page scans after replacing printer

Postby Loïc » Tue Dec 16, 2008 10:47 pm

Hi Derek,


Could you try to add this line:

Code: Select all
axImaging1.TwainDisableAutoSourceClose(True)


Just after this ones:
Code: Select all
if (axImaging1.TwainOpenDefaultSource() == true)
                {


Now what is the behaviour (please give me the log) with your second scanner ?

Best regards,

Loïc

Unfortunately it does the same thing. It loads the second page in the scanner, but does not go through.

Here is the log with the TwainDisableAutoSourceClose(true) added:

Hi,

The logs shows that your TWAIN device required to be closed after the first page acquisition (what gdtwain do).
Unfortunately I can't do anything more.

Maybe the driver is not the good one for this scanner ?
