Canon ImageFormula RS40 vs R40 – What’s the same?


Canon RS40 and R40 are two Sheetfed scanners that can help you scan documents automatically at the touch of a button. Both scanners use the ADF, or automatic document feeder, to feed and scan loose paper. They are very easy to use and are known for their quality.


When scanning A4 pages, you can reach a maximum speed of 40 pages per minute on both devices in black & white mode. Color pages take a little more time at 30 pages per minute of speed. This is mainly because they both use a fast CSI image sensor to make everything readable and faster than any other device on the market.


Speaking of power, both scanners run on a normal AC supply yet only use 22 watts of electricity on average. Both scanners also have a sleep mode that automatically turns on when you have not used the device for a long time. In speed mode expect to use less than 1.4 watts of power to really save money on electricity every month.


Both Canon scanners can store 60 sheets of paper and 40 photos without using an external tray. You can also store IDs, business cards, and receipts under the same hood without running out of space while working with multiple files.


Each scanner has an optical resolution of 600 x 600 dpi, which is more suitable for office work rather than creative areas. Also, you can increase the resolution artificially to 1200 dpi for better image quality and card scanning.

Duplex Options

If you want to scan sides of a document, the Canon RS40 and R40 are perfect for you. Now you don’t have to manually enter every page again into the scan to cover both sides. This makes the scanning process easier and less time-consuming when you are working on multiple tasks at the same time.

Duty Cycle

You get a monthly duty cycle limit of 4,000 pages, which is more than enough for any casual user. With this large duty cycle, multiple users can use the same device and still not reach the full scan limit.

Display & Controls

Both Canon scanners have a square text display that shows you one setting at a time. You can control both devices from the front panel, which has several touch buttons to quickly change settings before scanning a document or image.


Simply connect both scanners to a computer, laptop, or other smart devices with a USB 2.0 port on the back. Sadly, there is no Wi-Fi option to manage scans over the network from a phone or tablet.


Like every other Canon scanner, you get a one-year warranty from the brand from the date of purchase. So, people can apply for repairs and replacements if there is a defect with their device. Also, you must keep the warranty card safe that comes in the box to avail any service over the following year.
