CanoScan 8400F Scanner (2005) and macOS 10.12.6 on a brand new iMac (2017).
Back in late 2012 the scanner would not work with my then new iMac running Mt. Lion. Canon had not updated its driver (and has not since). Fortunately someone named “rabrack” figured out a way to create a driver that would work and posted it on this forum. It worked just fine on that computer through El Capitan, but something changed when I changed computers and the OS and now the scanner is dead again.
The messages that I get start with “Cannot communicate with scanner” and end with “Failed to open a driver.” In between they suggest checking the connections, but they are unchanged - I did double check. I also went to System Preferences and find that the scanner is not listed nor does it show up if I ask it to add a device, even though it is connected and turned on.
So, is “rabrack” still out there solving this problem? If not, has someone else come up with something? I do not want to get another scanner since there is nothing physically wrong with this one and it does what I want it to do (copies, pdfs, photos, old slides/film). What to do?
Dec 2, 2016 - At this stage, I have established from Canon that there is no plan for new drivers for the CanoScan 8400F driver. Instead, Canon suggests to use the Windows 7.
