Description
The Contex HD Ultra X 3650 is a 36-inch CCD large-format scanner built for technical professionals who need archival-grade image quality alongside dependable everyday scan speed.
Part of Contex's HD Ultra X series, the 3650 pairs premium Fujifilm-lensed CCD imaging with a compact 36" scan width, matched precisely to Arch D and E-size drawings, making it a strong fit for architecture, engineering, and reprographics operations that need superior depth of field and color accuracy without stepping up to a 42" or 60" system.
Where CIS scanners struggle with warped, thick, or damaged originals, the HD Ultra X 3650's CCD sensor array and 0.3" depth of focus capture consistent detail across historical drawings, fine art, maps, and technical documents alike.
The scanner requires no warm-up time, detects paper size automatically, and adjusts to media thickness up to 0.6" (15mm) via OTAC (Optimal Thickness Adjustment Control). It ships standard at 8.9 ips in 200 dpi color, upgradeable to 17.8 ips, and is available in three workflow configurations: stand-alone, Nextimage Remote (tablet-controlled), or ScanStation Pro (all-in-one with built-in PC).
Why choose the Contex HD Ultra X 3650:

- Instant-ON operation — No warm-up time means you start scanning immediately
- Speed upgrade path — Ships at 8.9 ips color, upgradeable to 17.8 ips as workflow demands grow
- Handles fragile & thick originals — OTAC thickness control accommodates media up to 15mm, ideal for archival and preservation work
- Three workflow options — Stand-alone, Nextimage Remote, or ScanStation Pro configurations fit different office setups

Contex HD Ultra X 3650 Frequently Asked Questions
Quick Answer: The HD Ultra X 3650 uses CCD sensors with premium Fujifilm lenses, giving it greater depth of field and color accuracy than CIS scanners — ideal for thick, warped, or archival originals.
What makes the CCD technology in the HD Ultra X 3650 different from CIS scanners?
CCD (Charge-Coupled Device) scanners use a lens-based optical path rather than the close-contact sensor used in CIS scanners. This gives the HD Ultra X 3650 a 0.3" depth of focus, allowing it to hold sharp focus on warped, curled, or uneven originals that would blur or distort on a CIS scanner. Combined with premium Fujifilm lenses, this makes the 3650 well suited to fine art, aged archival documents, and color-critical technical drawings.
Quick Answer: The 3650 scans at 8.9 ips in 200 dpi color out of the box, with a software upgrade path to 17.8 ips as your scanning volume grows.
Can I upgrade the scan speed on the HD Ultra X 3650 later?
Yes. The HD Ultra X 3650 ships standard at 8.9 inches per second in 200 dpi color (17.8 ips in grayscale/monochrome), with an upgrade path to 17.8 ips color. This lets firms start at a lower price point and scale speed as production volume increases, without replacing the scanner. Contact TAVCO for current upgrade pricing and availability.
Quick Answer: Yes — OTAC (Optimal Thickness Adjustment Control) automatically adjusts to media up to 0.6" (15mm) thick, handling mounted artwork, boards, and fragile originals.
Can the HD Ultra X 3650 handle thick, rigid, or fragile originals?
The HD Ultra X 3650 is designed for demanding media handling. Its OTAC (Optimal Thickness Adjustment Control) automatically adjusts to originals up to 15mm thick, while the CCD sensor's superior depth of field keeps warped or damaged documents in focus. This combination makes it well suited to historical archive digitization and preservation projects where originals can't be run through contact-based scanners.
Quick Answer: The 3650 is available as a stand-alone unit, with Nextimage Remote tablet control, or as a ScanStation Pro with a built-in PC — three configurations to match different office workflows.
What workflow configurations does the HD Ultra X 3650 come in?
Contex offers three ways to run the HD Ultra X 3650: Stand-alone (operate Nextimage software from a separate PC), Nextimage Remote (control scanning from a tablet app, free for iOS and Android), and ScanStation Pro (Nextimage software runs directly on a PC built into the scanner stand). Each configuration uses the same scanner hardware, so you can choose the workflow that fits your office space and IT setup.
Quick Answer: The 3650 includes a 30-day Nextimage software trial with TWAIN driver; Nextimage Scan+Archive, Nextimage Repro, and the Nextimage Remote tablet app are available as optional add-ons.
What software comes with the HD Ultra X 3650?
Every HD Ultra X 3650 includes a 30-day trial of Nextimage software with TWAIN driver (license sold separately). Optional software includes Nextimage Scan+Archive for document management workflows, Nextimage Repro for reprographics production, and the free Nextimage Remote tablet app for iOS and Android. The scanner outputs BigTIFF, TIFF, JPG, PDF/A, DWF, CALS, JPEG-2000, and other formats compatible with AutoCAD, ESRI, and most CAD/GIS platforms.
Quick Answer: Yes — TAVCO includes free phone and web-based installation with a certified technician, plus free freight shipping within the continental USA.
Is installation included when I purchase the HD Ultra X 3650 from TAVCO?
Yes. TAVCO includes free phone and web-based installation support with a certified technician for every HD Ultra X 3650 purchase, along with free freight shipping within the continental USA. Our team will help configure the scanner, set up your chosen software workflow, and get your team scanning productively from day one.
Quick Answer: The 36" scan width and 43.3" maximum media width comfortably cover Arch D and E-size drawings, the most common sizes in architecture and engineering offices.
What size drawings can the HD Ultra X 3650 scan?
With a 36-inch (914mm) maximum scan width and 43.3-inch (1100mm) maximum media width, the HD Ultra X 3650 handles Arch D-size (24"x36") and E-size (36"x48") drawings directly, plus most oversized or bordered originals within that range. For firms regularly working with 42" E1-size or 44" architectural sheets, the HD Ultra X 4250 or 4290 offer additional scan width headroom.
Quick Answer: Yes — the HD Ultra X 3650 is TAA-compliant when the version assembled in Denmark is specified for US customers, making it eligible for federal and government procurement.
Is the HD Ultra X 3650 available in a TAA-compliant configuration for government purchasing?
Yes. Contex offers a TAA-compliant version of the HD Ultra X 3650, assembled in Denmark specifically for US customers, that meets Trade Agreements Act requirements for federal, state, and municipal procurement. Contact TAVCO to confirm the availability of current TAA-compliant units and lead times for government contracts.
