Network scanner blocked by firewall

I have a Brother MCF-7820N (printer / scanner) connected via Lan to my router (fritzbox).
Printing ist no problem, but scanning (twain / WIA) is somehow blocked by the McAfee-firewall (error TW006). It only works when I temporarely disable the firewall.

I tried to allow the udp-Ports needed acdcording to Brother (54926, 137, 161) with no effect.

Any ideas or suggestions?

Add UDP Port No. 54925 and the IP address (Single) of Network printer in McAfee Firewall. Open McAfee, Select Privacy > My Network. Trust the (Device) Printer/scanner from the Network Map
