Canon LiDE 400 Colour Flatbed Scanner Review

Digital storage of the data is becoming increasingly popular and efficient nowadays.  Many record-keeping processes now include computers and data is stored on databases, not in huge outdated storage spaces like years ago. The data can be stored in a digital format for much longer than storing it physically.  What if you have valuable documentation and old photos and need a great scanner? You would like to extend their life, and not worry about the paper being ripped or otherwise destroyed.

In addition to doing a brilliant job of scanning pictures, the LiDE 400 focuses much more on scanning and processing of text documents than the previous model, making it much more appropriate for processing scanned content into editable text.

The Canon LiDE 400 is not only the same size and diameter as the LiDE 220, but it is also remarkably similar to the Epson Perfection V39 as its dimensions are 1.7 by 14.5 by 9.9 inches (HWD) and it weighs only 3.6 pounds. In other terms, all of these scanner models will take more or less the same desk space. Instead of lying plain on your table, the LiDE 400 makes up for this with a plastic kickstand-like footing that holds the scanner upright. Epson V39 has the same characteristics.

The LiDE 400 can be controlled from the front side five-button settings menu or from the CD-ROM software package that comes in the box. As with most scanners, the program offers a much more flexible range of scan functionality and destination choices than the control panel. However, it is important to note that the LiDE 400 attaches to and interacts with only one user, a single device attached to the scanner via the USB cable in the package, irrespective of which option you select.

Key Features and Benefits

  • This device utilises the Contact Image Sensor (CIS) technology. It means that the object you are scanning should be in direct contact with the glass surface. If the document is off the surface then the scan will be blurry.
  • The detachable stand is included in order to support the scanner while using less desk space. I prefer to put the scanner flat on the table since I need to press the document or notebook to get the appropriate scan.
  • This scanner will scan up to a maximum size of A4. If you need to scan bigger images or documents, scan multiple times and do the stitching accordingly. The auto-stitching feature is included in the driver but some auto-correction is also applied.
  • The 300 DPI scanning speed is pretty fast. It is about 8-10s. At 600 DPI the speed decreases to just over 30 seconds.
  • The scanner is impressively fast and sharp. A scan of a high-resolution photo or document of 4,800 x 4,800 dpi is made in just 8 seconds, thanks to Canon LiDE technology.

The LiDE 400 utilises a Type C USB to Type-A cable whereas the LiDE 300 uses the standard Type-A USB to Mini USB cable. Documents included in the box say that you can’t use the Canon LiDE 400 cable for other purposes but you obviously can. You can use the same cable to charge phones and to transfer data. And if the cable is lost or destroyed you can quickly get a substitute.

The device lacks support for wireless or wired networking, portable connectivity, mobile applications, and wireless scanning, although you can send scans to the cloud by saving them from the LiDE 400 software in a folder that syncs with a cloud site. Alternatively, to enable certain mobile and remote scanning functions, the scanning device needs to have an internet connection or at best a network. This does not come with a direct USB connection.


  • You can quickly scan and save multi-page PDF’s that are editable and searchable with OCR4 with the built-in PDF buttons.
  • With Auto Scan Mode3, the scanner automatically adjusts settings by detecting what you are scanning.
  • You can preserve detailed photos and images with the 4800 x 4800 dpi resolution, and with image enhancements, such as colour restore and dust removal, your photos will continue to look great.
  • With Send to Cloud, you can easily upload your photos and documents right to Cloud services like Microsoft OneDrive and Dropbox.
  • This scanner is looking great so far and it is easy to download the Canon’s software.


  • It is noisy when it is scanning rapidly. If you are in the workplace using this device, your surrounding coworkers will notice it. If you scan at 600 DPI, it’s much quieter as the speed gets slow.

The Canon LiDE 400 will scan to a maximum of 4800 DPI resolution. LiDE 300 scans to a maximum of 2400 DPI. You have to do it through ScanGear to scan at the highest resolution. By opening ScanGear and looking at the drop-down menu of the resolution, you will see that there is no 4800 mentioned among the choices so you have to enter the numbers yourself.

The tools on the packaged CD-ROM include the IJ Scan Utility’s PC and Mac versions, the scanner drivers and a collection of single-function utilities like Auto Scan, Document Scan, Photo Scan, Custom Scan, Stitch Scan, and OCR (optical character recognition) to convert scanned text to fully editable text.

Canon’s ScanGear utility is also included that is reachable via the Scan Utility. ScanGear is a TWAIN scanner user interface that operates inside TWAIN-compliant programs like Adobe Photoshop, Photoshop Essentials, Microsoft Word, PowerPoint, and many others which enables you to scan directly into these programs. ScanGear also lets you choose an interface, Basic or Advanced, based on your level of experience.

Stitch Scan is also a nice feature that allows you to scan larger pages than that supported by LiDE 400. You move the paper on the glass to use it, and the scanner scan sections that the program “stitches” back together.

The five buttons that are present on the front side panel of the scanner and their functions are described below,

Start: This function scans the paper on the glass scanner bed and transfers the scan to the computer. The scanner then waits, seeking you to either change the page on the panel or to click the Finish button. The computer can start a new multipage PDF to hold scans of this session or if you click Finish after the first scan, it will save the document to a single-page PDF. Nonetheless, pressing the Finish button progresses your scan task to the next stage.

Finish: The finish function stops the scanning operation and the PDF is saved. The number of pages included in the saved PDF depends on how many pages you can scan before pushing this button.

Auto Scan: It recognises, scans and then saves the object placed on the glass to an appropriate file type, such as an image or a searchable PDF, JPEG, TIFF, and PNG.

Copy: This function scans the glass’ contents and transfers it to a dedicated printer, via the computer.

Send: It transfers your scans for further processing, to a given email address or application, such as a PDF software utility.

The vertical installation and operation holder saves useful Desk space. This compact scanner’s stylish design fits into any home or office setting. With a press of a button, it provides high quality and accurate scans, etc. Due to the Z hinge even large documents with a thickness of up to 21 mm can be conveniently scanned.

If you’re searching for a simple entry-level image and document scanning, you won’t be unhappy with the LiDE 400. The LiDE 300, will save you a little bit of money, but it’s not enough to compromise the LiDE 400’s kickstand and higher-resolution scanning in my point of view.

The LiDE 400 is a flatbed photo scanner with the added advantage of well-developed functionality for text scanning and conversion. Previously, the biggest concern about its predecessor LiDE 220 was that it has a limited user interface and software. Canon has solved that by adding a package of tools close to what the company provides with its image printers of a high standard.

The LiDE 400 is a premium flatbed scanner with enhanced speed and high-resolution capability. The scanner generously saves desk space, power and time of scanning. It has a sophisticated and compact design, upright stand and single USB Type-C powered connection that makes it an ideal choice for home or office use.
