@all I am having an issue with Brother ADS scanner for Roligo Pelham, the scanner is working through iprint app, but it is not working using twain, I removed the scanner from the twain_32 folder and twain_64 and installed the scanner driver but it still not responding when using twack or carestask, also tried rebooting the scanner, power cycle, restarted the pc, but nothing works, only the twain driver is stuck, any ideas?

A Windows application titled **"TWAIN_32 Twacker (Not Responding)"** is displayed with a frozen/unresponsive state indicated in the title bar. In the background, a scanner selection interface is partially visible, listing **Brother MFC-L2700DW series**, **Brother MFC-L2710DW series**, and **Brother PC-FAX v3.2** as available devices. No error codes are visible; the only diagnostic indicator is the **(Not Responding)** status in the application title bar.

There are 2 twacker apps twack_32 and track_64, didn't work on any of them?

Tech A 2024-11-15 19:09

I tried both, and any of them are working, kept not responding

Tech B 2024-11-15 19:11

And you installed the driver from scratch, right?

Tech A 2024-11-15 19:11

right

Tech B 2024-11-15 19:11

# Fix Brother Scanner TWAIN Driver Not Responding

## Problem

Brother ADS scanner TWAIN driver becomes unresponsive when accessed through TWAIN applications like Twacker or Carestask. The scanner functions normally through other applications (like iprint app), but both TWAIN_32 Twacker and TWAIN_64 Twacker display "Not Responding" status when attempting to use the Brother scanner. Standard troubleshooting steps including driver reinstallation, scanner power cycling, and PC restart do not resolve the issue.

## Resolution

1. Disable the LogMeIn firewall policy
2. Test TWAIN functionality with the scanner

The LogMeIn firewall policy was blocking the TWAIN driver communication, preventing proper scanner operation through TWAIN applications while allowing other scanner functions to work normally.
