Bottom Line We love this scanner for its speed, user-friendliness, and also it's all-around performance at a fair priceGreat performance from a portable scanner that isn't to bad on the walletGreat performance for infrequent tasks, but not great for large tasks that require auto feeding and higher speedsWhile not the fastest, it excels in every aspect at a relatively low priceYou can give it a try without any risk, and packs a lot of performance into a phone app, but isn't great for longer documents

Our Analysis and Test Results

For years, few companies have been able to compete with Fujitsu's ScanSnap line of scanners. Still, the Canon ImageFORMULA R40 seriously challenges that superiority and does it at a much lower price point. It also managed to beat the top models when it came down to black and white receipt and document scanning quality. So if you are specifically looking for the best black and white scanning performance, you can do it for less than the premium price of other top-performing scanners.

Scanning Performance


The Canon ImageFORMULA R40 performed exceptionally well in our scanning performance tests and earned the most impressive performance black and white scanning that we've ever recorded. It also managed to do very well in our color photo scanning tests.


For black and white scanning, we tested the ability of the ImageFORMULA to scan various documents, including tax forms and receipts. We also evaluated the ability to digitize contrast, blotchy print, and handwriting with clarity.

The Canon ImageFORMULA R40 achieved perfection across our black and white scanning sub-metric for incredible performance on our receipt quality, text clarity, and handwriting quality tests.

It was also quite accurate when it came to scanning full-color photos. The color accuracy in the resulting scans was very accurate, just not as good as the models that did slightly better in this test. This model also made a little more adjustment to brightness than other top models, darkening some areas and brightening others. The R40 did a great job when it came down to sharpness. This model was almost perfect at maintaining the sharpness of the original photos.

Speed


In the world of scanners, speed matters almost as much as quality for most tasks. For example, a device without a feed tray can make scanning a 30-page document (or a 10-page presentation) an unnecessarily long and manual task. Some scanners also require more time for a slow or inferior optical sensor to scan a document. Fortunately, the Canon ImageFORMULA R40 is a fast scanner, and that speed does not compromise accuracy or quality.


The Canon had a great performance in our single-page test. It scans a single sheet document on the duplex, double-sided, 600 dpi color setting in just six seconds. We timed its ability to feed and scan 10-page documents on the duplex 600 dpi black and white setting, where it took 36 seconds. In other words, it averages 16.7 pages per minute.

Our last test scanned a 10-page document on a 600 dpi black and white setting, where it completed the task again in 36 seconds.

Software


We've never tested a scanner that has been able to perform perfect optical character recognition, although a few have come close. The Canon ImageFORMULA R40 is one of those models that are able to come very close.


Optical character recognition is an important software-based feature that turns printed and handwritten records into digitized documents. Digitization makes documents easier to organize and search through, but not all scanners or software are created equal. Some devices struggle to recognize the text on a blotchy receipt. Others have a higher error rate and poor performance due to less capable software, but the ImageFORMULA excelled in our tests.

For incredibly accurate performance in our optical character recognition test, the Canon performed quite well.

A few major platforms are used on desktops and work devices today, so multi-platform compatibility is a huge factor when rating software. So is the quality of that software. The software included with the Canon is both PC and Mac compatible.

Not only is it compatible with both operating systems, but it is also quality software with a nice user interface and design. The user experience is straightforward, making it easy to navigate settings, make selections, tailor those settings to your needs, and even save presets.

Ease of Use


We rated the user-friendliness of the Canon ImageFORMULA R40 with the rating split into two major metrics — the setup and the user interface.


You need to have Canon's software installed on your laptop or desktop to start scanning documents. The Canon ImageFORMULA R40 ships with the multi-platform CanonOnTouch, Readiris, and Cardiris. It relies on the typical but robust TWAIN driver. That technical jargon may not scream user-friendly but put simply; the setup couldn't be easier. We had the software installed and were ready to start scanning in five minutes!

User-friendliness extends to the user interface and all the functions and features that make using the device as simple and straightforward as possible. The Canon ImageFORMULA R40 does very well in this area. Single-touch operation, an automatic 60-sheet feeder, and a large output tray make scanning large stacks of documents a breeze. The super-simple app lets you easily access settings and save presets for quicker scanning options.

The combination of an easy and expedient setup and the simple, intuitive interface earned this model made this an incredibly user-friendly model.

Should You Buy the Canon ImageFORMULA R40?


The Canon ImageFORMULA R40 is a premium scanner that offers accurate performance and incredible speeds. It performed above and beyond in almost every metric. This high-performing device rivals the best for a more affordable price. Whether you work in an office, your business requires the digitization of paper documents, or you just value speed and efficiency, you can get it all and at a great price. We recommend this scanner to anyone who wants the best and would rather get the best dollar-for-dollar performance available on the market today.

What Other Scanners Should You Consider?


The Canon ImageFORMULA R40 is one of the best scanners on the market today, the best when it comes to black and white scanning performance, and probably the best dollar-for-dollar value. However, the Fujitsu ScanSnap iX1600 takes overall performance to the next level and is the best in class. If your budget allows, then it would be worth considering the Fujitsu ScanSnap iX1600. If you are looking for a highly portable device to handle tasks on the go, then take a look at the Epson WorkForce ES-60W. It performs nearly as well as the best devices we've tested, with obvious caveats because of its compact design, but is easy to throw in a pack and take to the job site.
