Avision Scanner Download

[Billy Cregin]

Avisionis member of the TWAIN Working Group, a nonprofit organization that maintains TWAIN standard specification, data source manager, sample code, software protocol and applications programming interface (API) for regulating communication between software applications and imaging devices. For business application, the company offers color imaging scanners and multifunction printers, as well as document capture software.

The head office is located in Hsinchu Science and Industrial Park, and the company operates worldwide. Avision owns and operates four branch offices in China, Germany, the United States, and Japan, and employs approximately 2,000 individuals.

We tested it- we installed a new Windows 7 Embed 32bit, and we noticed that when we install the AV175+ scanner locally (without any internet connection) it was "install" the driver (means, it display that it was installed), But, when checking on device manager we discover that the driver wasnt installed AT ALL.It does pops up the Microsoft Windows Driver Search window that search for driver, But eventually without success:

We preform and implement live image from SAME working system that came from another SAME T530 Thin Cliet- Where the scanner IS WORKING. But we got strange thing:

The scanner got the same issue!

How it can be??

After all this mess, we realized that after we tried to install the WIA on the 175+, it suddenly began to receive a WIA error in a standard scan.

When we installed only the TWAIN driver everything worked properly.

We removed the 175+ installation and install only the TWAIN driver, and now its fine.

The AV186+ is a compact, high-speed color duplex scanner. Designed to scan both documents up to legal size and plastic ID cards, the AV186+ can be used to capture all the information you need in a fast, and reliable performance.

The scanner's straight paper path provides smooth and reliable paper transmit and less document jam. It also ensures thicker paper up to 400 g/m and embossed plastic cards up to 1.25mm can be transmitted smoothly.

For ease of use, nine scanning presets can be custom programmed for different applications. The entire scanning process is then as simple as selecting a preset and pressing the simplex or duplex scan button. Tasks such as scanning, and storing or sending the images to application become completely automated processes.

The AV186+ is also equipped with various innovative features such as automatic color detection, automatic blank-page detection, skew correction and ultrasonic multi-feed detection to catch overlapped pages. These features help users to digitize document effectively and efficiently.

The SANE/Avision backend is a high quality SANE scanner driver, supporting a wide range of original Avision as well as Avision OEM scanners. Commonly known OEM scanner include Visioneer, Xerox, Hewlett-Packard (HP 53xx, 74xx and 82xx series), Kodak ixx series, Fujitsu ScanPartner, Mitsubishi sheet-feed scanners as well as Minolta film-scanner.

A short list of the most important features:

all scan-modi ("Line Art", "Dithered", "Gray", "Color", "16bit-Gray" and "16bit-Color")

all resolutions up to whatever the scanner reports as optical resolution (please only use the common modes [like 400 or 600] or you'll get scanner - interpolated images with some artifacts ...)

gamma-table for color-correction in the scanner using the full internal color range

hardware color calibration - for high-precision color correction in scanner

various ADF models including duplex scans are supported

film-scannners support

transparency adapters are supported

first SANE backend with support for monitoring scanner buttons!

fully endianess safe: runs on every day production use on PowerPC, Ultra SPARC and MIPS Linux systems!

In theory all original as well OEM Avision SCSI and USB scanners should work just fine; practice may differ.

2011:

Over the last years performance was improved for latest high speed duplex scanners, several new hardware features supported, error conditions handled more gracefully, and driver hooks added for auto-crop & de-skew. Support was added for about hundred new scanners.

2004:

A lot work as done for better ADF support including duplex scans. A lot of new scanner IDs have been added to the driver (HP 82xx series, Kodak ixx series as well as many many others) and support for USB 2.0 scanners has been added.

The backend got extended to support direct USB access. The hpusbscsi module is no longer needed and considered obsolete. The new user-space USB code should work for all platform where libusb is available - and the solution should become more stable, since the hpusbscsi module was quite touchy when it didn't like some bits.

2002:

Oliver Neukum sponsored a HP 5300 scanner and after two days the Avision backend was able to handle it!

Frank Zago contributed code to recognize and use Mitsubishi sheet-feed scanners.

Jose Paulo Moitinho de Almeida and me worked on the calibration algorithm.

Avision INC sponsored an AV 8000 (A3 size with ADF) for driver development!!! - Many thanks.

2001:

Some people found out that some HP USB scanner (HP 53xx and HP 74xx series) are Avision OEM scanners labelled by HP. So people started to ask for an modified backend to support this scanners. But since I did not had one it usually ended in oopsing kernels and endless debug message email handlind ... I asked HP at the CeBIT 2001 if they could provide a scanner for driver development. They tried to organize one - but going from manager to manager, they where not able to to this during one full year?!?

Jose Paulo Moitinho de Almeida started to contribute code to get his MINOLTA FS-V1 (aka: Dimage Scan Dual II) film-scanner to work with the Avision backend.

1997:

I bought a Avision AV630cs in 1997 because it is a really great scanner! But sometime later I completely switched to Linux. The problem was: There was no Avision support in SANE. SANE stands for Scanner Access Now Easy - a package of "scanner drivers" for Linux.

It is also nice that you have the same Graphical User Interface regardless which hardware you are acutally using. In Windows for example you get a professional UI with one driver and a car-radio style toy with another. - In Linux you have the same professional User Interface for all scanners.

Q: Does the backend support the scanner buttons?

A: Yes, the Avision backend was the first one introducing such a functionality. I implemented a tiny demo daemon and there is a graphical KDE systray program available as well.

Q: The backend report a wrong sheet size?

A: Some Avision scanners report no (AV 630) or a wrong scan-area. Use the "option force-a4" option in your sane config file (e.g. /usr/etc/sane.d/avision).

Q: Do the HP (53xx and 74xx series) or other Avision OEM scanner (such as the Minolta Dimage dia/film scanner or Xeros, Kodak, ... document scanner) work?

A: Yes. They should all work now. Only the 5370 has some image-corruption problems and the 7400 needs to be some tweaking for ADF. Please try the latest source available.

Q: Does the Avision parallel scanners work?

A: No. I do not own a parallel-port-scanner and at this day of age they are not really important for us. I got private eMails from other people who try to log and "decypher" the parallel-port-traffic, but there is no useable code, yet.

It is always welcome if people report success or ideas for new features. Please also think about the possibility to donate to this project since developing such a high-quality and cross platform driver takes a lot of time.

To subscribe to the sane-avision mailing list, send a mail with the subject subscribe sane-avision to li...@exactcode.de. The list will get Subversion commit mails as well as milestone reports. In addition the list is open for general discussion and users are free to ask quetions, outline problems, ask for improvements or just report success.

Since I have not all the hardware with all possible features, it might happens from time to time that the backend does not work optimal with a scanner - or maybe doesn't do anything with a new scanner at all.

(It is also possible to use any SANE based application (even GUI based like xscanimage, xsane or kooka) to generate the log. Simply start the GUI application in a xterm (or gnome-terminal, konsole, ...), do the "export SANE_DEBUG_AVISION=7" and start you GUI application in the same terminal)

Avision has adopted Dynamsoft's barcode reader software development kit (SDK) to create new barcode scanning and reading software for many of the company's document scanners sold throughout North America and other parts of the world. Original Equipment Manufacturers (OEMs) in the USA and Canada sell these scanners into government, finance and education markets that more and more heavily use barcode technology.

The new barcode capabilities are now included in 55 Avision scanner models. This includes the company's three best-selling models: the AV176+ office desktop scanner, the AV188 compact duplex scanner for documents and plastic ID cards, and the AV122 series which is the company's most compact high speed document scanner. The SDK used for the barcode software allowed Avision to more easily ensure key features were supported, such as file name and barcode type segmentation. The Avision software is Button Manager V2, which is installed on local computers. It is provided bundled on a disc or via download for free with related scanner purchases.

We opted for a technology partnership with Dynamsoft for their barcode reader SDK and we quickly realized many technical and business advantages," said Leo Liao, Software Manager, Avision. Dynamsoft's SDK allowed us to implement barcode technology within a week's time. Had we opted to try and do it ourselves it could have taken nearly a year. Dynamsoft's SDK not only helped provide the robust software we wanted to develop, it also saved us extensively in development time and money."
