Spoke with 3x different Brother Support folks. We verified it’s not in Firewall on computers, but after that they don’t know.
I found it!!! It’s setting in the Brother printer…. It depends on the network card you have in system on computer that’s connecting….. That’s why Older Systems did not have a delay from Scan to Screen Display…..!!!!
IF Printer Network settings have IPv6 ON: AND: Your LAN is IPv4, AND, the network card SUPPORTS IPv6: THEN you get the 1- 1.5 min delay on Scan to screen Display! WINDOWS OR IOS!
IF Printer Network settings have IPv6 ON: AND: Your LAN is IPv4, AND, the network card DOE NOT SUPPORT IPv6: THEN you get a Scan to screen Display IMMEDIATELY! WINDOWS (ASSUME IOS TOO)!
IF YOU TURN OFF IPv6, AND: Your LAN is IPv4, THEN you get a Scan to screen Display IMMEDIATELY! WINDOWS OR IOS!
Brother default Network config turns on IPV6….. THAT is causing the delay on SCAN to Screen Display of the scan!!!
If your LAN is IPv4: IN BROTHER PRINTER, NO MATTER IF DHCP OR STATIC IP….. TURN OFF IPV6!
That fixes the 1 minute (or more) delay in displaying scanned image!!!
I’m kind of confused that since I set an IPv4 Static IP, that system would/should have turned off IPv6, as a precautionary action for their own Apps???? I guess not! (Machine NOT Smarter than Operator!)
YIPPEE FIXED!!!!
