Space-Saving Design, Professional-Grade Results
The SD One X is engineered for teams that scan architectural drawings, construction plans, and engineering documents on a regular basis but don’t need the full stand-alone touchscreen controller of the SD One MF. Connect via USB 3.0, launch Nextimage 7, and you’re scanning in minutes.
Compact enough to sit beside your wide-format plotter. Powerful enough to meet federal FADGI 3-star digitization standards. The SD One X delivers on both counts.
Patented Color Fringe Removal — The Cleanest CIS Scans Available
CIS (Contact Image Sensor) scanners are fast and compact, but the sequential red-green-blue illumination common to most CIS designs produces color fringing on fine lines and text — a chronic problem when digitizing CAD drawings and blueprints.
Contex holds the patent on Color Fringe Removal (CFR) technology, and the SD One X uses it. The result: crisp, fringe-free scans even on highly detailed engineering drawings with fine dimension lines. This is the difference between a scan you can archive and a scan you actually use.
FADGI 3-Star Compliance — Archive-Ready from Day One
The Federal Agencies Digital Guidelines Initiative (FADGI) rating system is the benchmark for digitization quality. Scanning with 4 exposures per scan line — and operating under Nextimage 7 — pushes the SD One X past the FADGI 3-star threshold. If your projects involve public records, government submittals, or long-term archiving, this matters.
Built for AEC Workflows
Whether you’re an architect digitizing legacy permit sets, a contractor scanning redline mark-ups, or a property manager archiving HOA construction documents, the SD One X handles it all:
- Blueprints & CAD drawings — up to 44″ wide in a single pass
- Maps and site plans — full-color at 600 dpi optical resolution
- Permit documents — direct output to TIFF, JPEG, or PDF
- Engineering schematics — shadow-free scans with dual LED illumination

Frequently Asked Questions
Q: What is the Contex SD One X used for?
A: The SD One X is designed for scanning oversized documents including architectural drawings, blueprints, engineering plans, maps, and construction documents up to 44 inches wide. It’s ideal for architecture, engineering, and construction firms that need fast, accurate in-house digitizing.
Q: How does the SD One X compare to the SD One MF?
A: The SD One X is a streamlined scanner that connects to a PC via USB and is operated through Nextimage 7 software. The SD One MF adds a large built-in touchscreen controller, allowing stand-alone scanning, annotation, and direct cloud sharing without a computer. The SD One X is the right choice if you already have a dedicated scanning workstation; the SD One MF is better for shared team environments or PC-free operation.
Q: Does the Contex SD One X meet FADGI standards?
A: Yes. Operating the SD One X with Nextimage 7 software exceeds the FADGI 3-star digitization standard — the highest practical rating in FADGI’s 4-star system. This makes it suitable for government archiving, public record digitization, and long-term document preservation projects.
Q: What sizes does the Contex SD One X come in?
A: The SD One X is available in 24-inch, 36-inch, and 44-inch scanning widths. The 36-inch model handles standard D-size (22″×34″) and E-size (34″×44″) drawings; the 44-inch model accommodates the widest architectural and engineering formats.
Q: Can I use the SD One X with my existing plotter or printer?
A: Yes. The SD One X includes native printer drivers for Canon, HP, Epson, and OCÉ wide-format printers, turning your existing setup into a copy/scan/print workstation.
