Thanks for reply. One more question. Seems like TWAIN_32.DLL presents WIA drivers while TWAINDSM.DLL does not (at least 32 bit version). Is this correct ? If so why ? Any configuration ?
(WIA drivers is usually very limited in functionallity so personally I think it is good, “novice” user might be using WIA driver by mistake)
For the future it might be wise to have some kind og possiblity for an app to check if a driver is a WIA driver or a “pure” Twain driver.
I wondered why TWAINDSM.DLL (32 bit) does not show WIA drivers while TWAIN_32 does.
32 bit, to my knowledge there is no 64 bit WIA drivers for professional document scanners.
Any WIA driver visible with TWAIN_32.DLL
Sorry for late reply, got a mail today that you answered. There is a demo version on http://www.pixedit.com and the latest version is 8
Our application PixEdit is fully tested with 64 bit Twain drivers. At least one vendor of (professional) document scanners have released true 64 bit drivers and other are in the process. See http://www.pixedit.com, PixEdit PRO comes in a 64 bit version which runs 64 bit drivers.
Have both these scanners here and many others. What are you looking for ?
I still have this problem on i1440 and i620 but runs OK on several other scanners like i1320 Plus, 4500. Do you have any information how to solve this ?
Seems like Kodak drivers acts different between models. Strange.
Good idea. Should come from Twain.org. You have Twister but it reports doubtful info on certain scanners. See http://www.dosadi.com/twister.htm
Agree. A lot of the Twaindrivers are “bad” in many ways and many features, even recommended, may be omitted. But this does not tell ISIS is better than Twain. It only tells what amount of work the manufacturer has put into the driver/software for the scanner. If they where to do a certification prosess like in ISIS the scanner itself or the driver would cost more. Why is it typically a Twaindriver and not an ISIS driver following a scanner to 150$ ? In general the Twaindrivers are very good for business document scanners, like from Canon and Panasonic. But don’t expect much of a scanner more built for home usage.
Agree. Have not any experience with Brother Twain drivers but quality of Twaindrivers vary a lot. But this is not the fault of Twain standard. In my experince the ISIS driver is usually of high quality, they are probably tested qute a lot and reliable. But so are Twaindrivers from many manufacturers also, like from Canon DR scanners and Panasonic document scanners. With Twain you may create a driver with minimum effort and make it work to a certain degree with most (all most all) Twain compliant programs. And the manufacturer may choose how much effort they want to put in development into SW driver – functionality and quality. So if you have a cheap “home” scanner do not expect a high performance driver with a lot of functions – actually you do not need it because you will not buy a $200 scanner together with scanning software to $2000 and vice versa. Also, again based on experience, putting too much “advanced document processing” functions into the scanner itself is not good. In some case it will work but very often not because of the wide varity of type of documents customers scan. Like automatic detection of blank pages and so on. It is much better to put such funtionality into the receiving application. Such fancy stuff costs if they are put into the scanner. Then when the scanner is worn out you will have to pay for this again. If it is in the software (scanning program) tou may use these functions again and again, also on existing historic files, from MFDs or whatever.
Sorry, maybe I was a bit fast. What I meant was you have an application that supports Twain so it can be used on any Twain compliant scanner (could be an expensive document scanner, a small simple Brother, an MFD or whatever). This application does the scan and process the document automatically, PDF/A, OCR, remove blank pages ..) so you have the full functionallity you need for your documents. So it does not matter if you buy a new model of your scanner, you get the same result out. This application puts the the “finished” documents to a folder for importing into your medical system, database system or whatever it is. Typically, in a good designed such system, it supports some kind of automatic import so the scanning application reads barcodes on the documents and names the outputfiles according to the barcodes making an automatic import possible – this will in most cases save a lot of manual work and reduces costs. But here we are more into a good design of the medical/database system, not so much Twain. The scanning application should also be able to support folder import so instead of scanning with Twain it automatically picks up files coming into a folder from MFDs, processes them and put them to the importfolder of the database system. This also opens up for the possiblity to scan with any scanning application and have “proper” documents go into storage in the database whatever the source is, like maybe you get a Tiff file on mail form some customer but you have standardized on PDF/A in your database you just drop the file in a folder and it will be converted and imported. I totally agree with you there is no single solution here, different needs. However the “scanning and import” application should be flexible enough to handle most situations and be configurable in both ends, the source and the destination. Hopefully this clarified a bittNovember 13, 2009 at 11:36 am in reply to: Memory related errors when using Canon X10C high speed scan #24901
The driver runs just fine with PixEdit in production environment I know
Just an input, if you are scanning this amount of pages in color you will have a REAL speed problem if you do not switch to compressed scanning. You should have a professional application beeing able to process and save this amount of data in real-time (unless you have a very slow scanner that is). Afterwards spilt and save to indivdual files on specific directories. Also think of the diskspace/filesize. Any page it is possible to convert from color to grayscale or black and white and greyscale to black and white is essential. Or better : use compression like PDF/A Compact which is able to compress pages with only some color data on it very good without loosing image quality.
PixEdit would probably do it all for you, Twain scan, doc to pdf, tiff to pdf, pdf to tiff, ocr and more.
Can you post an e-mail adr to the Kodak engineers ?
