Toshiba MR-4000B Dual Scan Document Feeder (DSDF)

The Toshiba MR-4000B Dual Scan Document Feeder (DSDF) is a high-performance document feeder designed for compatible Toshiba e-STUDIO multifunction printers. It is built for offices, institutions, corporate environments, and professional workgroups that regularly handle multi-page and double-sided documents.

Unlike a conventional reversing document feeder, the MR-4000B uses dual scanning technology to capture both sides of a two-sided original without physically reversing the sheet. This makes duplex scanning faster and more efficient for digitizing contracts, reports, invoices, forms, records, and other business documents.

Dual Scan Document Feeding

The MR-4000B is a Dual Scan Document Feeder (DSDF) designed to process both sides of compatible two-sided originals efficiently during scanning and copying.

Simultaneous Duplex Scanning

Dual scanning technology captures the front and back of a document during a single pass, eliminating the reversing process required by traditional RADF systems.

High-Speed Duplex Workflows

The single-pass design improves productivity when scanning large quantities of double-sided documents, making it ideal for busy document-management environments.

Automatic Multi-Page Feeding

Automatically feeds multi-page originals through a compatible Toshiba e-STUDIO multifunction printer, reducing manual document handling during scanning and copying.

Supports A3 Originals

Designed to accommodate originals up to A3 size, making it suitable for standard office documents as well as larger reports, forms, diagrams, and business records.

Flexible Original Handling

Efficient Document Digitization

Ideal for converting large batches of paper documents into digital files for archiving, email distribution, document management, and network storage.

Engineered as an original Toshiba accessory for supported e-STUDIO multifunction systems, providing integrated operation with compatible scanning and copying functions.

Ideal for High-Volume Offices
