brother MFC won't scan last page
I have a Brother MFC-7840W that for years worked beautifully with a Mac Pro running 10.13.6 High Sierra. No issues printing or scanning that I can recall. Brother is on the wired network, not directly attached to either computer.
I'm now using a current M1 MacBook Pro running 12.6. For some reason when scanning a multipage document it fails to save the scan of the last page. Doesn't matter how many pages it is, the last one always gets dropped. The paper is physically fed through the machine correctly and it seems to scan just fine, built in scanner software even shows a preview of the last page. But somewhere along the way the last page is dropped and isn't appended to the PDF like all the other ones are.
Any suggestions?
