The ‘Xpress’ difference

Colortrac SC SmartLF Xpress series is now even faster for everyday scanning tasks.  At 200 dpi the paper speed has been doubled which means that an A0 / E size document scanned in 24-bit colour now scans at a full 12 inches per second, very nearly the same speed as a monochrome scan.   At 300 dpi the speed has also been doubled.  Scan speeds at higher dpis are not affected.  This performance requires a USB3 enabled computer connection.  For USB2 connections these speeds will be halved.

SingleSensor Technology

Colortrac SmartLF SC Xpress Series – A well-proven, innovative technology for great wide format image quality. SingleSensor is a Colortrac invention that combines CIS elements and LEDs in a single line for maximum scan accuracy and optimal illumination. Reliable and affordable scanning with a fast return on investment.  Get the job done ‘super-fast’ with no stopping or waiting.

Larger Document Staging Area

The new design incorporates a larger face-upstaging platform to make loading documents into the scanner faster and easier.  SC 42 Xpress is the first Colortrac scanner designed specifically to auto-size documents face-up in the centre of the scanner, a change which helps the operator to see what they are scanning and also to load creased documents more effectively.  For documents conforming to standard drawing sheet sizes (manual mode) the scanner can accept media side & center using SmartWorks Pro or at the side only using the SmartWorks TOUCH software.  An included magnetic paper guide accessory can be used to maximise side margin accuracy where required.  With a straight-through paper path the SC 42 Xpress has a maximum media width of 44” (1117mm) and scans documents and maps up to 0.08″ (2 mm) in thickness.  This is more than enough to meet the requirements of AEC, CAD, GIS and the majority of work done by copyshop or service bureaux.

Dynamic Document Feed

Driven rollers either side of the optical path and an active soft pressure roller running the full length of the SingleSensor allow the scanner to dynamically respond and actively work against the optical disturbances caused by document lift and paper creasing.  This technology ensures that delicate or fragile media such as newspaper and old blueprints can be safely and accurately scanned without problem.

SuperSpeed PC Interface

The SmartLF SC 42 Xpress is the first large format scanner to incorporate the new SuperSpeed USB 3.0 digital interface.  With a dramatic x10 increase in the internal data transfer rates, the new USB 3.0 interface works at up to 5Gb/sec.   In terms of speed of scan data saved to the computer this represents more than double the previous rate of 28MB/sec (USB2) to 65 -85 MB/sec for USB3 depending on computer manufacturer.  SuperSpeed USB 3.0 is unique to Colortrac and allows the SmartLF SC 42 Xpress scanner to work at full speed using higher resolutions on wider documents than ever before.  For those without a USB3 equipped computer SmartLF SC 42 Xpress enhanced USB2 circuitry achieves a 25% improvement in data speed (35MB/sec) above the previously recognised industry average transfer rate of 28MB/sec for a normal USB2 equipped pc. Higher data transfer gives the SmartLF SC 42 Xpress operator the freedom to scan wider and at higher resolutions without affecting productivity.  If you have large amounts of archiving then SmartLF SC 42 is the perfect solution.
