Canon R40 vs R50 – What’s the same?

Type & Speed

Featuring the same brand Canon R40 and R50 are sheet-fed scanners that are mainly used to scan a huge number of documents at once. Both scanners have a top feed tray that stores papers for you to scan later. The max speed of both devices is 40 ppm to help you quickly get work done with minimal manual work needed.

Scan Modes

Each device has three different scan modes, so you can choose between color, grayscale, and monochrome depending on the task. Scan speed and time can also be affected by selecting one of the options, which is why it’s important to know what you want beforehand.

Light Source

Both Canon scanners are equipped with an LED light source that contains three different color options. The LED is based on RGB (Red, Green, Blue) which works with the CIS image sensor to read the document and find the right size and make adjustments automatically.


With any of the above Canon scanners, you get a resolution of 600 dpi, which shows how many dots per inch are used when scanning documents. The higher the resolution, the better the image quality when working with a color scanner. As a result, the Canon R40 and R50 scanners are highly detailed with generally accurate colors and lines, to improve document quality.

Document Feeder

Both devices come with a manual and automatic document feeder (ADF) that works around the color to help you minimize human effort. The document feeder on both scanners can take 60 sheets at once to help you scan in bulk without wearing down the entire system.

Duplex Scanning & Single Pass

Both Canon scanners are equipped with a duplex function so you can automatically scan sheets of paper on both sides. This greatly simplifies the scanning process and reduces the amount of work involved in turning each page. Single-pass duplex is another great feature on both devices, allowing you to feed a page only once and save the information on both sides to later convert into a digital document.

Duty Cycle

Surprisingly, both Canon scanners have the same average monthly duty cycle. You can scan 4,000 documents per month without damaging the internal components of your scanner. However, maxing out the monthly duty cycle is not recommended as this can reduce the life of the scanner by many years.

Compatible OS

Both scanners are compatible with Windows and macOS but there is no official support for Linux operating systems. People warning on Linux OS can definitely use the device but you’ll have to deal with software issues at first, so choosing another device that supports Linux is the best advice we can give to such people.


Consumers do not have to pay for repairs and maintenance during the one-year warranty period. So, if you receive a product that is defective or damaged in transit, you can simply return the scanner to Canon and request a refund. Remember to always keep the warranty card included in the box for the benefits that the company claims.

Canon R40 vs R50 – What’s so different?

Design & Build

When comparing the design between Canon R40 and R50 we found some drastic changes. The Canon R40 is a bit bigger in size and also takes more space on top of any take because of the minor differences. When comparing weight, the Canon R50 features a heavier frame than the R40.

Media Support

Both scanners support a wide variety of media but the media weight capacity differs. The Canon R50 can handle pages with more width to unlock more sizes than the R40 that loses by a small margin. So, people who work with different thickness of paper can choose the upgraded modem and not run into incompatibility issues.


Although both scanners share the same USB port, the wireless option is only available with one device. The updated Canon R50 has built-in Wi-Fi that connects to a phone, tablet, laptop, or other smart devices to scan documents without being physically connected to the scanner.


If you need a more energy-efficient scanner, you should go with the Canon R40, because this device consumes only 22 watts of electricity and 1.4 watts in sleep mode. While the Canon R50 consumes 22.5 watts of electricity at full power and consumes 3.1 watts more in sleep mode, which is much higher than the first device.


You get a large screen with the touch screen support of the Canon R50 to operate the entire scanner with ease, while other devices only offer small screens which can be tricky for beginners. So, if you need a better touch surface and a big screen, you should go for the Canon R50 color scanner.
