Well, I can't advise you on which scanner to buy or comment on your plan 
because my scanning requirements are trivial compared to the job you're 
preparing for. My Brother DS-740D mobile scanner handles all my 
lightweight scanning needs, which is digitizing various documents into 
PDF forms on an occasional basis.

I do feel reasonably confident based off of the information on the SANE 
Project website that the Canon scanner you're thinking of purchasing 
will be recognized and ready for operation when you plug it in. How well 
will it perform? Will the driver and utility programs support all the 
features of the device? Are they bug free? I couldn't tell you as I 
don't have experience with that hardware and have not needed a scanner 
suitable to do the task you're set to do.

Since you mentioned VueScan in second post, I would give serious 
consideration to purchasing a copy or a monthly subscription. You can 
even cancel the subscription when you sign on, so you'll have use of the 
software for 30 days if that's all you needed it for. The programmer has 
worked on and sold the software for almost a quarter of century, the 
Canon LiDE 400 scanner is reported as supported, a new version was just 
released 8 days ago, their offering a 20% percent discount on new 
purchases, you can install the software and get trial access to the 
professional features to try it out, and there's a 7-day money-back 
guarantee. I know I sound like a paid promoter, lol, but I'm not. I was 
set to purchase VueScan a couple of years ago had the opensource 
programs not worked with my scanner, but they did so I passed on it. But 
its nice to have the option if the free stuff doesn't work well.
