Twain scanning no longer working

[TJTim]

Has anyone else run into a Twain scanning issue lately? Scanning was working fine last week and now the Twain driver never shows up as an option. This involves several users with different printer/scanners installed. It just doesn't work anymore. One thing that has changed was Microsoft's latest 'Cumulative' update to Windows 10. That pushed out last week and is installed on all of the Twain users PCs. I guess I'm just hoping for a fix!

Thanks!

Please try some troubleshoot option available in the link https://helpx.adobe.com/acrobat/kb/troubleshoot-scanner-issues-acrobat.html. If the issue still persists please share the following details.

- Acrobat version

- Scanner details

- OS exact version

Thanks.

Hi Lovekesh,

I am having the same issue the last few days and it is driving me nuts.  I have already tried all of the steps in the troubleshoot link you supplied.  The scanner works great with photoshop and other applications, just not Acrobat.  Please help.

• Acrobat Standard 11.0.23
• Brother MFC-8480DN running the latest drivers
• Windows 7 Pro x64 which also received a monthly cumulative update.

The troubleshooting steps were of no help. Twain scanning works fine in EVERYTHING else, just not in Acrobat.

Hi TJTim,

We have the same issue and the troubleshooting article from Adobe doesnt fix it.  This is not an isolated issue and an update should be made to address this or at least more support from Adobe staff to figure out better steps to remedy the issue than the troubleshoot article.

Acrobat 11 standard on Windows 7 Pro x64 worked great for years with a Brother MFC scanner on a small office network connected via ethernet cable.  All of sudden, Acrobate will no longer detect this scanner.  However, I can use photoshop to connect to the scanner.  I use Acrobate to scan documents to pdf and this issue is really annoying.  Please help.

I have tried the following with no success:

• Uninstall Brother software and Acrobat and reinstall and update.
• Check for any driver updates
• Manually search for any drivers or folders with Twain and delete them.  I then re-installed the most current Brother drivers.
• Tried selecting "Custom Scan" to see if I can select a different scanner or un-hide any scanners.  There is no "hide" option in the custom scan box of Acrobat Standard 11.

Update on Resolution for My Issue:

Windows update installed two updates KB4346080 and KB4343894 on 9/4/18.

Nothing else was changed on the system configuration or software and Acrobat 11 Standard now recognizes my scanner drivers.  So the issue seems to be fixed for me.

I am not sure if this will fix other Acrobate versions or Windows operating systems but some recent windows updates from 9/4/18 were installed and today my Acrobate scanning drivers work again.  Hopefully, others will get fixed.  The scanner troubleshooting page from Adobe was not helpful with this issue.

I support several users.  This is a chronic problem.  Acrobat periodically refuses to acknowledge the TWAIN driver.  Installing all updates: WSUS's, Acrobat, Scanner Drivers sometimes helps, then sometimes not.  User has to use the "Custom" mode which is not all that desireable. You cannot save the settings, so they have to be selected every scan. In "Custom" Acrobat scan's every document to whatever size page you select.  But it all boils down to: Why does Acrobat refuse to acknowledge the TWAIN drivers?  Especially since it previously recognized them?  We use various Fujitsu Scanners.  6110 (which I have the least problems with), 6130, 7160, 7030, 7060.  Why I spend 8 hours a month supporting Acrobat not recognizing drivers is frustrating.

I'm running Acrobat Pro 2017.011.30171 on Windows 10 version 1909

I recently reinstalled my Brother MFC software, and now I can't scan with Acrobat Pro 2017. I can scan using other software using the TWAIN driver, just not Acrobat.

In Acrobat, if I go to the setup ("Enhance Scans") to configure predefined settings for B&W document, the TW-Brother DCP-L2550DW scanner is displayed. But I can not change the Resolution and Paper Sizes fields. And if I click the scan button, I get an error message advising me to:

Please input some valid page dimensions". Screen shot
