Commonly called "Technology Without An Interesting Name," TWAINs are very important. They are also a relatively unknown technology in the imaging industry. Jim Ramey, DentiMax Imaging Director, explains what a TWAIN driver is.
TWAIN, is a protocol that allows an imaging device to acquire an image (initially flat-bed scanners). It saves that image directly into a "TWAIN compliant" imaging software application. Software applications (such as Photoshop) need this information.
In the early 1990s, dental practices found it very difficult to get a scanner to communicate with a PC. It also involved the scanner acquiring images into the applications everyone wanted to use. Standardization did not even exist for file types. Many scanner companies had their own "proprietary" image files. That could only work with the software they made and created by the devices they made!
Back in 1992, representatives of some of the largest companies in the imaging industry got together. Their intention involved standardizing the communication between the imaging software and the hardware that created those images. They created the TWAIN Working Group and developed the initial toolkit in 1992. Since then, updates have occurred every so often. The last one occurred in 2015.
They set the word TWAIN itself in all caps to make it stand out from other "tech speak" coming out at the time. This led many to believe that this word was an acronym. And the acronym theory persists even to this day. One of the most common definitions calls it "Technology Without an Interesting Name." Some even wrote this as the "official" meaning of the word.
However, this is not correct. The official website for the TWAIN working group states that their first choice was unavailable. They chose TWAIN based on the phrase "never the twain shall meet". It also means "two"; an imaging hardware device and an imaging software application connecting. The official meaning of the chosen term TWAIN, also referenced the extreme difficulty that devices like scanners had in the early 90s communicating with the image applications designed to work with those acquired images.
Many TWAINs have an interface or a screen that allows the end-user to preview the image they are acquiring. The image management software is called the "calling application" when talking about TWAINs. The imaging software "calls" the TWAIN driver, which will initiate the acquisition from the imaging device.
If there is an interface, this will launch. Or, as with a scanner, you would push the scan button (with other devices, the acquisition process will differ slightly. Refer to the device manual or technical support from the device manufacturer.) It acquires the image and returns it automatically to the calling application. From there you can save the image and do whatever you need to do with the newly acquired image!
The TWAIN will not work if the computer cannot "see" the device before installing the TWAIN driver. Another way some people think of the TWAIN is that it is a "translator" so that whatever type of image that you are acquiring, the TWAIN will allow that device to capture and save directly into the imaging software that you are working with, "translating" between the device and the software so they can communicate with each other directly.
The TWAIN Working Group maintains the TWAIN SDK and API that companies globally use to develop their TWAIN drivers to capture images with their devices and save them into any TWAIN-compliant image software application.
These devices have a TWAIN that allows practices to capture the images into whatever imaging application your practice uses. The digital pans, especially early on, were FAR too expensive for the manufacturers to tell practices what imaging software they needed to capture images. This explains why the digital panoramic units all have a TWAIN driver that you can get from the device manufacturer to capture your panoramic X-rays directly into your image management application.
Just like most digital cameras, a few manufacturers of the SLR cameras gained popularity within the dental industry. Digital cameras were one of the initial devices that needed the TWAIN drivers, so they still have them. Now with image file formats more standardized, a device driver will often already install itself when you plug your digital camera into your computer. (Most cameras will save in a common file format which most computers can use natively) Alternatively, you can go to a disk/website to download and install the device driver and the TWAIN.
So you click acquire once and capture all the images you need for your series in the DentiMax interface. Then you can click "stop capture" and "return images." All the images return to the correct tiles and all stay oriented correctly.
TWAIN focuses on allowing any imaging device to "communicate" with any image application. Of course, some developers of TWAIN drivers adhere to the TWAIN standard more closely than others. Once in a great while you may run into a device conflicts with your specific image management program. Usually, though, they work great and are an excellent way to use different devices in your image management software other than the specific device the software came with.
Emails and calls to Cannon technical support have not helped. After two rounds of the typical "reinstall...", they sent some patch, which did not help. This seems to be a known problem in user reports and the Cannon support staff, but no solutions.
It works until the next reboot. I keep the Services app pinned to my task bar with Name sorted in reverse order so I can quickly get to the WIA service. I have uninstalled/reinstalled with the latest drivers and software and nothing else works for me.
Is the scanner connected directly to a USB port on the laptop or motherboard? Since you have already investigated the software route, have you tried replacing the cable and testing on a different port?
Desktop, usb via hub. I don't see how it is hardware, since it works fine always after reboot for a day+, and then fails. I can try moving the connection after a failure, but hardware wouldn't give that symptom i don;t think.
Hi Guthrie. I see that you are getting a TWAIN driver error (80FF0001) when you try to use your imageFORMULA R40 and you have installed the patch we sent you. If you did not reach out to us after installing the patch, please call us at 1-800-652-2666, Monday - Friday 8:00 A.M. - 8:00 P.M. ET (excluding holidays). If you have already contacted us, we recommend that you check with your computer's manufacturer. We have seen that security programs may interfere with the TWAIN driver, so if you have any running, you can contact the company that makes that software. Thanks for your contributions to the community.
I would like to see some logging information from your tool, or some resolution of the actual error message. So far I have only gotten generic responses - Reinstall, try this patch, update, maybe it is hardware (which symptoms do not match), ...
I am having the same problem, however re-booting does not work for me. What did work for a few days was moving the usb cable to another usb port, but now that does not work. So my scanner is useless for now.
Thanks for the quick reply Brianinca. Customer has been using a Xerox scanner in the past but keep having problems with the vendor software just stop working with it. By the time we removed it and reinstall a couple of times, got it working with the vendors software, it would break the Xerox / ScanSoft software. So the customer ordered the ScanSnap, did not ask me before ordering, but I would have thought the ScanSnap would support the older Twain.
I found Xerox had updated their driver and software (win10) for the Documate 152, removed the ScanSnap and installed the new Xerox driver and software and it worked in both OneTouch and the vendors software. Just how long will be the question.
Setup with QuickBooks should be fairly simple given that the DS-530 is TWAIN complaint. This article provides a step-by-step guide to setting up QuickBooks Scan Manager, which you might find helpful. If you have any other questions, please feel free to give me a shout!
I setup a new pc for customer today, win 10 Pro. New out of box ScanSnap ix500, install the cd, took default everything. It wanted to check of update for the software, found updates but I declined to download. Did a reboot and tried to scan, did not work, scanner now listed. Allowed the download and install of the updates, the S pops up, ready to scan. Did a couple test scans, working correct.
I have a Kodak i2800 scanner connected to LF Scanning using a TWAIN driver on a Windows 7 64-bit machine. When initiating a scan, the scanner will pull pages through the feeder, but nothing is transferred to LF Scanning. When the scanner is done, the LF Scanning application does not seem to be aware of this, and it's still waiting for the images. The Red X button on the toolbar that will stop the scanning is enabled, as if it's still scanning/waiting for images.
This problem happens intermittently. Thinking that this might be a scanner issue, I've had this same scanner running on a Quick Fields workstation using the same TWAIN driver without any issues like this at all.
The problem I'm running into now is that if I use the ISIS driver with LFScanning, no image comes through at all. An entry is created in the Scanned Documents list, but there is no image at all. Another issue is that the scanner scans on page at a time with a pause of about 1-2 seconds between each page.
As you can see below in the screenshot, it has an option for ScanAhead. When disabled within this app, the scanner behaves "slowly" just like in LFScanning. When I enable ScanAhead, then it scans normal and fast. However, this app does not display an image, it simply shows a message that says X amount of pages were scanned.
Yes, using the Testappn.exe app, when turning off the Scan Ahead feature it behaves very differently. It scans a single page, waits 2 seconds, then scans the next page etc. When enabled, it scans normally. However, this setting is only available inside this standalone app, there does not seem to be a setting for it elsewhere.
