Overview

The Contex HD Ultra X 4290 is a high-performance, wide-format CCD scanner engineered for professional reprographics, engineering, mapping, graphics, and archival workflows. Designed with speed, accuracy, and media flexibility in mind, it delivers sharp, color-accurate scans of large documents at high throughput.

Key Features & Benefits

Wide Format & Media Handling

Scans up to 42 inches (1,067 mm) wide; capable of handling documents of unlimited length.
Accommodates media thickness up to 0.6 in (15 mm) — including mounted, rigid, or foam-board documents.
Equipped with Optimized Thickness Adjustment Control (OTAC) for fast, one-lever adjustment to match media thickness.
FlexDoc and FlexFeed technologies provide robust handling of a variety of media types, from thin originals to thick boards, while maintaining correct feed and pressure on the document.

Imaging & Color Quality

Optical resolution: 1,200 dpi
Maximum (interpolated) resolution: 9,600 dpi Contex
Uses advanced CCD technology with 5 × 4 linear color CCDs (RGB + gray) to capture full 48-bit color data.
Accuracy Lens Enhancement (ALE) ensures precision across the scanning width, maintaining 0.1% ± 1 pixel accuracy.
AccuColor ensures color fidelity and full 48-bit data handling through the scanner.

Speed & Productivity

Color scanning speed: 17.8 inches per second (ips) at 200 dpi RGB.
Offers “instant-on” / no warm-up capability, minimizing downtime.
Designed for high throughput: can handle hundreds of large-format scans per hour in batch operations.
1 GB onboard buffer reduces pauses during scanning, ensuring smooth data flow.

Workflow & Usability
