Advantages of 64-bit hardware and software

More physical memory for large image files
A 32-bit system architecture can directly address only a 4-GB address space. Windows 10 that is running a 64-bit can support up to 2TB of physical memory.

Faster bus architecture
A 64-bit architecture provides more and wider general-purpose registers, which contribute to greater overall application speed. Function calls are also faster in a 64-bit environment because as many as four arguments at a time can be passed in registers to a function.

Full 64-bit solutions

All Contex applications are full 64 bit. Nextimage, Nextimage TWAIN, WIDEsystem drivers and the Software Development Kit all have been updated to a full 64 bit architecture.

Features that matter

SD One+ gives you all the features you need to create a great scan, easily.

SD One+ is a compact scanner available in the two sizes to support your document needs. The 24″ model (scanning up to 610 mm wide) will scan documents up to A1 / D. The 36″ model (scanning up to 914 mm wide) supports even larger documents up to A0 / E size. Both models are compact and light enough to place on your desk or the optional stand.
SD One+ is a fully featured wide format scanner, designed to meet all your needs. With free software included, you can take on and clean-up the oldest and most damaged documents with SD One+. Equally suited to capturing fine lines with the highest possible accuracy, SD One+ with Nextimage software is a combination you can trust. SD one+ is designed for Windows 8, 7 and Vista.
The Cloud enabled SD One+ scanner can send documents directly to your preferred destinations. The only choice you have to make is where you need the documents – SD One+ handles the rest. SD One+ can deliver images by e-mail or directly into your cloud sharing and storage applications. There is a long list of supported Cloud destinations like DropBox,, Google Drive and many more.
SD One+ supports standard document formats like PDF and PDF/A. These are formats that can be opened and printed in scale using the free Adobe Reader. With PDF/A you even benefit from a format that is protected from changes and designed for long time storage. We recommend PDF/A to store your as-builts and documentation. To share and collaborate use standard PDF as this enables highlighting and annotations.
Using a standard USB connection enables connection to any PC or laptop. Simply install the scanning application that comes with the scanner and connect it to your PC. You may install the scanner on as many PC’s as you like. The compact size and low weight of the SD One+ enables you to keep it on your desk. You may also use the optional stand if you prefer.
