Greetings all; This scanner in an MFC-9620DW works well with the brother drivers if one is not in a hurry.
I investigated the delays and found the networking portion of the Brother Drivers are sending the first 6 packets, at 1 second intervals, with bad TCP checksum according to tcpdump. The scanner of course rightfully ignores them. Then their driver seems to get it all in the same sock for the rest of the scan. I have not traced a multisheet scan as yet, but this 7 seconds delay is present regardless of whether the sheet is on the glass, or in the in hopper of the ASF. This has been reported to Brother twice now, but no one has responded with a fix. I would assume this doesn't occur with the usb interface, but to use it, I'd need a usb cable about 3 meters long as that socket is also at the end of a long molded in ditch in the housing accessable by lifting the whole scanner on hinges, but the ditch is a good 30" of cable to negotiate, so its only possible if I add yet another hub, locating it close enough, or find an un-hubbed usb cable long enough to reach. Is this driver possibly a WIP? Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
