ES-400 II vs ES-500W II Comparison
Connectivity options
The Epson WorkForce ES-500W II stands out with built-in wireless capability, allowing you to scan directly from smartphones, tablets, or computers without a cable. You can use the Epson Smart Panel mobile app for this flexibility. The ES-400 II relies on a standard wired connection, as wireless features are not listed in its specifications. Both models support TWAIN drivers for seamless integration with document management software on your desktop. If you need to move the scanner or share it across a network without cables, the wireless option is a clear advantage. The wired model is reliable but less flexible for mobile workflows.
Scan speed
The ES-500W II offers a published scan speed of 35 pages per minute (ppm) and 70 image per minute (ipm) for duplex jobs. This Single-Step Technology captures both sides of a document in one pass. The ES-400 II is described as high-speed, but its specific pages-per-minute rating is not provided in the available data. Both machines handle stacks efficiently with their 50-sheet auto document feeders. For heavy-volume tasks, the ES-500W II provides concrete performance metrics that help you plan your workflow. The ES-400 II is efficient, but the ES-500W II gives you the exact numbers to verify it meets your speed requirements.
Physical dimensions
Both scanners share the same width of 11.6 inches and height of 6.9 inches, making them similar in footprint depth. However, the ES-500W II is longer at 11.6 inches, while the ES-400 II is shorter at 6.6 inches. This makes the ES-400 II more compact for tight desk spaces. The ES-500W II weighs 8.1 pounds, and the ES-400 II weighs 8.16 pounds, so they are nearly identical in weight. If desk space is limited, the shorter ES-400 II fits better. If you have ample room, the extra length of the ES-500W II does not hinder placement.
Image processing features
Both models use Epson Image Processing Technology for automatic adjustments like cropping, blank page removal, and background removal. They also share Optical Character Recognition (OCR) for searchable PDFs and conversion to editable Word or Excel files. The ES-500W II explicitly lists dirt detection and paper-skew correction as additional intelligent features. The ES-400 II mentions dynamic skew correction and ultrasonic double feed detection for reliability. While both handle basic adjustments well, the ES-500W II offers more detailed image correction tools. The ES-400 II focuses on feeding reliability. Both ensure clean, professional scans for your documents.
Software integration
Both scanners include Epson ScanSmart software, which lets you preview scans, email files, and upload to cloud services like Dropbox, Evernote, Google Drive, and OneDrive. They both support TWAIN drivers for integration with most document management software. The ES-500W II adds mobile app support via the Epson Smart Panel app for wireless scanning from iOS and Android devices. The ES-400 II does not list mobile app capabilities. If you frequently scan from your phone or tablet, the ES-500W II provides a smoother experience. For desktop-only workflows, both offer identical software features and cloud connectivity options.
Which Epson Scanner Should You Buy?

Buyers prioritizing speed and features
The ES-500W II specifies a scan speed of 35 pages per minute and 70 images per minute. It also lists intelligent image adjustments like dirt detection and background removal.
