Hi, i was setting up a Brother ADS- 2700W Scanner, it had already a Static Ip via Ethernet, just installe its Drivers, and worked just fine with its Brother Iprint&Scan, and with Windows Scann default program, but From Carestack is not working. Deleted Cache and cookies,restarted PC, CareStack still not scanning, stopped and re enable WIA from services.

**Brother iPrint&Scan** application is open on a Windows desktop, displaying a **Brother ADS-2700W** document scanner at IP address **10.0.14.241** with status indicator showing **"Ready"** (green checkmark). A dropdown menu in the **Scan Settings** panel lists multiple available devices: TW-Brother ADS-2700W LAN, TW-Brother MFC-L2710DW LAN, Canon MF731/733\_F80D60E90C59, WIA-Brother MFC-L2710DW LAN, WIA-Canon MF731/733 (Network: F80), and **WIA-Brother ADS-2700W LAN** (currently highlighted in green). No error codes or physical damage are visible.

When clicking on Carestack Last Scanner option (the one that got added when we installed the printer drivers) is showing this error, we confirmed.Net is updated

A Microsoft .NET Framework dialog box displays an unhandled exception error with the message: **"Error opening data source."** The dialog offers three options: **Details**, **Continue**, and **Quit**, and states the application will either ignore the error and continue or close immediately depending on user selection. The background application appears to be a scanning interface showing **"0 of 0"** pages loaded.

Does it work if you test it at twacker?

Tech B 2024-11-05 16:33

I think that carestak uses twain devices, not 100% sure

Tech B 2024-11-05 16:34

Try to use the 1st one, it's the twain option

Tech A 2024-11-05 16:34

we did, is not doing anything.

Tech C 2024-11-05 16:35

☝🏻

Tech A 2024-11-05 16:38

did not work either.

Tech C 2024-11-05 16:38

can you give us a bit more details?

Tech C 2024-11-05 16:38

when you say "did not work", what do you mean?

Tech C 2024-11-05 16:38

error?

Tech C 2024-11-05 16:38

or did not show up in TWACKER?

Tech A 2024-11-05 16:39

it does show up, but then once selected when i click Acquire it does nothing.

Tech B 2024-11-05 16:41

Hmmm it should open the scan interface from Brother iPrint&Scan when you choose the twain option at twacker

Tech B 2024-11-05 16:41

Have you restarted the computer after installing it? just in case

Tech C 2024-11-05 16:41

then you have TWAIN drivers issues.

Tech A 2024-11-05 16:42

yes i have restarted it!

Tech C 2024-11-05 16:47

do a clean reinstall - remove all Brother related software, remove all the folders, including the one in twain_32 folder as well as all registry keys, reboot, reinstall

# Fix Brother ADS-2700W scanner TWAIN driver issues preventing CareStack scanning

## Problem

A Brother ADS-2700W scanner with static IP was successfully installed and working with Brother iPrint&Scan and Windows default scanning program, but failed to function with CareStack. When attempting to use the scanner through CareStack, a Microsoft .NET Framework error appeared with the message "Error opening data source." The scanner was visible in TWACKER and could be selected, but clicking "Acquire" produced no response, indicating TWAIN driver communication issues.

## Resolution

1. Uninstall all Brother-related software from the system
2. Navigate to the TWAIN_32 folder and delete all Brother scanner folders
3. Remove all Brother-related registry keys from the Windows registry
4. Restart the computer
5. Reinstall the Brother ADS-2700W drivers from scratch
6. Test TWAIN functionality using TWACKER before attempting to use with CareStack

The issue stems from corrupted or incomplete TWAIN driver installation that prevents proper communication between the scanner and TWAIN-compatible applications like CareStack, even when WIA drivers function correctly.
