Epson V39 II vs Canon LiDE 400: A Flatbed for Prints and Pages
Epson V39 II vs Canon LiDE 400 is a sensible starting comparison for digitising printed photographs and occasional paperwork without buying a large film-scanning system. Both are slim USB-powered flatbeds with 4800 dpi optical resolution. The more useful differences are software, handling and how comfortably the scanner fits your desk.

Quick verdict
Consider the V39 II for its ScanSmart workflow and removable raised lid. Consider the LiDE 400 if Canon's scanning software and one-cable USB-C connection suit your computer. Neither is a dedicated negative or slide scanner; choose for reflective prints, pages and supported bound originals.
At a glance
Separate printed photos from transparent film
These scanners are candidates for a stack of photo prints, drawings and household pages. Do not assume a high dpi number makes them equivalent to a scanner with a transparency unit. Negative film and mounted slides need a suitable illuminated scanning arrangement and holders.
If you already have an all-in-one printer with a flatbed, compare what you gain from a separate scanner before buying. A compact dedicated unit may improve placement or workflow, but a very small archive may not justify another device. For mixed film and prints, investigate a model intended for both.
Check the software on your actual computer
Epson lists ScanSmart for the V39 II, while Canon provides its own scanning utilities for the LiDE 400. Confirm current downloads for the exact operating system before ordering. An old compatibility table in a listing should not be treated as a current support guarantee.
Some enhancement and document features vary by platform. If OCR, multi-page PDFs or a particular restoration tool is the reason you are buying, check that feature on your own Windows or Mac setup. Internet access may be required to obtain and install current software.

A convenient lid does not make a book disposable
The V39 II has a high-rise removable lid; the LiDE 400 uses an expanding lid arrangement. Those features help accommodate thicker originals, but they do not make forcing a tight book flat a good idea. Follow the manual and preserve the original's binding and surface.
Check the maximum scanning area against the pages and photos you have. Software stitching can be helpful for oversized artwork, but it is a separate process that may require careful alignment and checking. It does not turn the physical glass bed into a larger scanner.
Use an appropriate resolution for the job
The maximum optical figure is not a sensible default for every scan. Choose resolution for the detail in the original and the size of the output you intend to make. A huge file does not restore information missing from a soft or damaged print.
Try a representative image and inspect the result before committing to a large batch. Keep an unaltered scan when restoration matters, then save an edited version separately. Check cropping, rotation and colour correction so a one-click tool does not remove an important border or change the photograph more than you want.
Make desk access and file organisation part of the decision
USB power reduces the need for a separate wall supply, but confirm the cable, port and any adapter required by your computer. Leave space for the lid and keep the glass accessible for routine care. Storage upright is different from assuming every kind of original can be scanned comfortably in that position.
Price the complete connection setup and compare return terms. Establish folder names and a separate backup before the project grows. Either flatbed can be useful when its software and physical handling fit; the best purchase is the one you will use consistently rather than leave in a drawer.
Final choice
Choose the V39 II if its lid arrangement and ScanSmart workflow suit your originals. Choose the LiDE 400 if Canon's utility and USB-C connection suit your desk. Confirm current software support and keep transparent-film scanning as a separate requirement.
