I have not yet tried Windows 7 but am anxious to move from Vista Ultimate to Windows 7 Ultimate. The deal breaker will be some compatibility with my system. I have a Multitech MT5634ZPX-PCI-U V.34 (Super G3) analog modem for faxing. I also have a Canon
CanoScan 4200F scanner. I have a potent system with a Gigabyte MA790XT-UD4P motherboard, an AMD Phenom X4 955 Black Edition processor, 8 GB of 1066 DDR3 RAM and an ATI 512 MB 4770 Video card running Vista Ultimate 64 bit.
With Vista Fax & Scan I have not been able to get anything other than 14.4 kbps fax speed as it does not support V.34. Fax & Scan in Windows XP did support V.34 so I was just a little miffed. My other option, if it will work, is to use an old program I have
that was not Vista-compatible called Phone Tools eXPert 4.0 which does allow TWAIN scanners and is V.34 compatible if it will work in Virtual XP mode.
My Canon scanner with Vista 64 (or with Vista 32) does not have a WIA driver so it also did not work with Vista Fax & Scan.
Does Windows 7 Fax & Scan restore V.34 compatibility which should never have been removed? To any small business that faxes a lot off the desktop this is a real problem with long distance faxes in countries without unlimited faxing plans. V.34 reduced fax
page sending times from ~10 sec. to ~3 sec. With negotiation times included a 5 page fax is reduced from ~ 4 minutes to ~1.5 minutes.
Also, does Windows 7 Fax & Scan now support TWAIN-only scanner drivers or will I either have to purchase a new scanner with a WIA driver or use the CanoScan Toolbox?
I don't get it. No one seems to understand what I am asking.
THIS IS NOT about the respective drivers! It is about how Windows Fax & Scan handles those drivers.
For example, Windows Fax & Scan in Vista WILL NOT recognize a TWAIN-only driver even though Windows does. So a Canon CanoScan 4200F scanner will work in Vista if the user uses the Canon Toolkit or other TWAIN-compliant programs. However, if the user tries
to use Windows Fax & Scan to run the scanner, they will receive a message from Windows saying "No scanners were detected...". This is due to the fact that Windows Fax and Scan only looks for WIA drivers installed, not TWAIN drivers. When it doesn't see a
WIA driver it says that there is no scanner on the system. This makes no sense. Other programs such as the aforementioned Canon Toolkit and Snappy Fax recognize TWAIN drivers and will activate the scanner.
As for the modem, the driver for this modem is compliant with a large list of ITU-T specifications. It works just fine in Windows Vista if you only want standard fax speeds of 14.4 kbps (V.17). However, this modem is also capable of the V.34bis standard (Super
G3) and, if connecting with another Super G3 fax machine, is capable of sending and receiving faxes at 33.6 kbps. But it will only do that if the controlling fax program initializes the driver to allow V.34bis negotiation. Otherwise it will only negotiate
a connection at V.17 speed or 14.4 kbps. There are fax programs such as FaxTalk Messenger Pro 7.5 which will initialize the modem's V.34bis ability. However, Windows Fax & Scan in Vista WILL NOT do that because, for reasons best known to the programmers,
that compatibility was removed when the Windows Fax & Scan component was migrated to Vista from XP. Windows Fax & Scan in XP DOES support V.34bis.
So my question again is whether Windows Fax and Scan in Windows 7 has been fixed so that it recognizes TWAIN scanner drivers and the V.34bis specification in some modem drivers? Not all modems support V.34bis.
Hopefully, you now should understand what I am asking.
No, Windows 7 Fax & Scan will NOT work with a twain scanner. My Agfa scanner is twain (aren't all scanners these days?). It works perfectly with every other item of software on the PC, but not with Fax & Scan. Here's what happens:
I have posted in several places about this problem - which existed with Windows 7 Ultimate in Beta and RC1 versions, and is exactly the same in Home Premium which I installed earlier this week.
I'm back to using the scanner with Paint Shop Pro, then "printing" the scan to my old WinFax package. That works OK, and achieves the maximum speed the devices at each end of the line can handle. It's a kludge, but it works.
[Edit}: I'm not sure how this BB software handles images. That method works with every other BB I Use, but not here.
Since you are using the old WinFax you must be running it in XP mode as WinFax would not work in Vista. It is the same as Phone Tools in that regard. It has to do with the way printers are handled. Avanquest purchased BVRP, threw out Phone Tools eXPert
and Fax Tools eXPert by no longer supporting them, but fixed the module that wouldn't work with Vista in Phone Tools Classic which is the same engiine. Go figure.
Thanks for the heads up on the TWAIN driver incompatibility. This is a no brainer for Microsoft. Why are they not fixing it.
At Kingsclear, sorry for my poor english, I'm french...
But I have exactely the same problem that you, I installed Windows 7 professional on Windows XP and since my CanoScan 4200F scanner is out !
I installed the new drivers Canon 220.127.116.11a 64, I see the scanner in the control panel and for Windows all is OK, but any software "see" the scanner !
I wrote at Canon, I wait an answer... I think that a problem of driver Twain abandoned by Microsoft for the WIA driver. It's pity !
If anybody have a solution... Thanks before.
One would think that the engineers at Microsoft would see all this bickering about the lack of TWAIN support in Fax & Scan and fix it. But who am I to judge. What I don't get is that Microsoft in its infinite wisedom removed a simple V.34bis ITU-approved
compatibility in Fax and Scan. Why would they do this? It is absurd! There were no reported issues that I know of. The only thing I can think of is that only 2 modem manufacturers embraced V.34bis for computer modems. It is hard to find a good fax machine
Both Canon and Microsoft are complicit. Maybe I will get Canon to replace my scanner as they insist in not producing a WIA driver. Or maybe we could start a class-action suit? Calling all those owners of Canon CanoScan 4200F! We are going to sue Microsoft
and Canon together. Oh! I forgot. The lawyers will get all the money and we won't get a dime. Shucks!
