Plustek PS3140U Duplex Document Scanner

This scanner does not automatically detect document size. Users need to manually configure the scan settings for different paper sizes. This can be a minor inconvenience when scanning mixed-size documents, requiring more user intervention.

The Plustek PS3140U supports double-sided scanning, allowing it to scan both sides of a document in a single pass. This significantly reduces scanning time and effort, making it efficient for digitizing double-sided documents such as contracts and reports. It enhances productivity for office tasks.

The scanner can automatically determine whether to scan a document in color or monochrome based on its content. This feature streamlines the scanning process by eliminating the need to manually switch settings for documents containing both color and black-and-white elements. It simplifies the user experience.

The PS3140U includes a text enhancement function that improves the clarity of text in scanned images. This is particularly useful for enhancing the legibility of documents with faint or unclear text, making it beneficial for archiving old or low-quality documents. It ensures better readability of scanned text.

The scanner automatically corrects skewing and distortion in scanned images, producing clean, professional-looking scans even if the original document is slightly misaligned. This feature saves time by eliminating the need for manual adjustments, ensuring high-quality scans with minimal effort.

The Plustek PS3140U does not support direct uploading to cloud storage services like Google Drive or Dropbox. Scanned documents must be saved to a local computer or FTP server and then manually uploaded to the cloud. This lack of direct cloud integration may be a drawback for users relying on cloud-based workflows.
