Elements Organizer: need option to use WIA, and disable TWAIN

PSE10 does not install the TWAIN driver for the Editor, which is OK since WIA works fine. Why does Organizer not follow that procedure? I'd like to avoid loading unnecessary code as much as possible.

Elements Organizer does not use TWAIN, nor have the option of installing the TWAIN plug-in. It uses a modification of WIA.

TWAIN is a communication channel to the scanner driver. If you install the TWAIN driver in Editor and compare a TWAIN scan procedure to a WIA scan procedure, you will notice that the scan procedure in Organizer more closely resembles the WIA scan procedure (different dialog windows at first, but later the same dialog windows).

I spoke too soon.

How do you explain this dialog from Organizer when I selected File...Get Photos and Videos...From scanner?

Some WIA drivers just turn around and call TWAIN sources. That, and your scanner is disconnected, or the driver very confused...

There are no "WIA drivers". WIA is an acronym for Windows Image Acquisiton. It is the built-in subsystem that handles communication with scanners. The whole point of WIA is to not need to install drivers.

Of course my scanner is disconnected. The point of posting the image is to ask why Organizer is calling a TWAIN driver when, if as Brett said, Organizer does not use TWAIN.

"TWAIN-Lexmark 4300 Series" is simply the name of the driver as handed to Photoshop Elements by the WIA sub-system. This is just configuration semantics. Your scanner could be configured to be named "HTTP-Lexmark" and PSE would still be communicating with it through WIA.

Brett,
I don't think you're correct about that, for 4 reasons:

1. The device is listed as "Lexmark 4300 Series" in Win7's "Devices and Printers" window.
2. When I select "WIA Support" to scan in the PSE Editor, the device is listed as "Lexmark 4300 Series".
3. If I enable TWAIN support in PSE's Editor, the device is listed as "TWAIN Lexmark...".
4. I have another program which uses any and all scanners and drivers it can find on the system. My device is listed twice -- once as "TWAIN Lexmark..." and once as "Lexmark 4300...". Sure enough, if I select the TWAIN listing, the TWAIN UI is launched, if I select the plain "Lexmark" listing, the WIA interface is launched.

In short, in my experience, whenever a device's name begins with "TWAIN" it's using TWAIN. Whenever a device's name does not begin with "TWAIN", it's bypassing the TWAIN interface and using WIA directly.

I'm not sure how that would be happening. There is no TWAIN functionality in Organizer, it does not have a TWAIN plug-in, nor the option to install one. Is it possible to just remove the TWAIN driver for your scanner (some scanners have this option, but yours may not). Then we could see have the Organizer reacts to this.

It sounds almost as if WIA is picking up the TWAIN functionality of the scanner and passing that on to the Organizer. I'm not even sure if such a thing is supposed to be able to happen.

No, I won't go through the hassle of removing the TWAIN driver, testing Organizer, and then re-installing the TWAIN driver.

I stand by my 4 reasons why I think Organizer is using TWAIN....

I think you're right that when WIA is directly accessed, it's not supposed to "pick up" the TWAIN driver -- see my other discussion about WIA support in the Editor, and the example I gave of using Windows Paint.

Seems like your engineering department has some 'splaining to do!

Brett,
How do you explain this PSE10 Organizer Help page?

http://help.adobe.com/en_US/elementso...

which includes countless references to Organizer using TWAIN.

Hi Ken,

When TWAIN drivers are installed on your system and your scanner is attached, EO will show 2 entries - one for 'scanning via WIA' and another 'scanning via Twain'.

Sorry, Ankur, but that's not the way it works at all. PSE10's Organizer only pops up one entry -- the TWAIN entry.

See the Help file I referenced for an explanation of what's happening. Organizer uses the TWAIN driver when that driver is installed; no if's, and's, or but's.

I have a similar problem. Just purchased photoshop elements 10 and premiere elements 10. I have a samsung multifunction clx-6210fx network printer and scanner. I can scan using paperport but when I try using photoshop elements 10 it only shows the WIA option on the import menu, if I select that it says no compatible devices were detected. However if I open Premiere elements 10 it shows my samsung and I can scan from it which is rather strange when it is more a video program. It also shows a slide scanner which I no longer have that came with Adobe elements 8 and which I uninstalled after going through the de-registering procedure. I would like to be able to scan into Photoshop elements 10 rather than have to use premiere elements. In fact if I knew that premiere would handle photos perhaps I wasted money purchasing photoshop elements 10 as well. Any help would be appreciated

Twain scanner interfaces show up in the Organizer for pse 9, 10, 11 if you are running Windows. It does not work for the Mac.

Again, in windows, twain scanners will show up in the Editor ( File-->Import) if you copy the "optional plug-ins/Import-Export" folder into the "plug-ins" folder.

Twain drivers do not show up in the Organizer for pse 12.
DO NOT UPGRADE TO PSE 12!!! It adds a few small features and takes away several important features.

By the way, WIA does not work fine. It is a primitive interface.

The Canon Scangear twain driver is a full featured scanning tool that will do repairs in 16 bit mode. PSE tools work in 8 bit mode and can degrade the image.

If your twain driver includes levels and fading correction, do it there before you import the image into pse.
