The Colortrac SmartLF SC Xpress Series wide format scanners are designed to scan images fast at the optimum resolution required to capture the original image detail without compromising quality. Colortrac’s SingleSensor technology and ClearView instant-on bi-directional LED illumination system produce up to 1200 dpi of uncompromising resolution. Whatever condition of the original, SingleSensor produces unrivalled accurate image scans, even if the original is folded, creased or crumpled. ClearView’s even lighting prevents shadows and creases and combined with the Colortrac’s SureDrive roller feed system, provides even pressure across the full width of the document, pushing it against the scan glass at the critical moment of capture. The Smart LF SC Series supports colour management workflows and can capture a colour gamut that far exceeds the sRGB colour spaces, used as an industry recognised standard.

The Colortrac SmartLF SC Xpress Series is ideal for boosting productivity. In addition to fast scan speeds, even at high resolution, the SC Xpress Series features the new SuperSpeed USB 3.0 and optimised USB 2.0 digital interfaces. SuperSpeed data transfer means there are fewer communication bottlenecks and you can always scan the largest documents in the greatest detail fast. Colortrac’s ClearView LED lighting system uses instant-on low energy illumination technology and is Energy Star qualified.

Colortrac’s ScanOnce technology means no need to preview scans to adjust settings for a rescan because all editing is applied after the scan. ScanOnce saves the full dpi and allows the user to zoom, pan and edit on screen. The large staging platform makes loading documents into the scanner fast and easy. The SmartLF SC Xpress Series is designed specifically to auto-size documents face up in the centre of the scanner, which helps the operator see what they are scanning and load creased documents more effectively.

The Colortrac SmartLF SC Xpress Series includes SmartWorks Touch software and TWAIN driver. SmartWorks Touch is simple-to-use software for scanning, copying and printing. SmartWorks Touch features an intuitive interface designed for touch-screens or mouse and keyboard operation. SmartWorks Touch saves scans to PDF, PDF/A, MPDF, JPEG, JPEG2000, PNG, AutoCAD DWF, TIFF, TIFF LZW, TIF-G4, MTIFF, PCX, and BMP. Batch scanning, full preview and all Windows driven printers are supported with SmartWorks Touch. Colortrac’s WinSync optimises windows driver technology that allows you to easily connect Colortrac scanners to your PC. The TWAIN driver provides basic control over scanner colour mode, resolution and paper sizing settings. A compatible TWAIN application is required.


The Colortrac SmartLF SC Xpress Series features an optical resolution of 1200 dpi. Scan speeds are as follows:

The three configurations; monochrome, colour, and enhanced colour, are on-site software upgradable, so the Colortrac SmartLF SC Xpress Series can be upgraded quickly and easily as your requirements change.

The Colortrac SmartLF SC 42 Xpress scans up to 42 inches/106.7cm and can take a maximum media width up to 44 inches/111.7 cm. The Colortrac SmartLF SC Xpress Series accepts media up to 0.08 inches (2.0mm) thick. The minimum media size the Colortrac SmartLF SC Xpress Series can scan is 6 x 6 inches/15.2 x 15.2 cm. Maximum image length for scanning is 96 inches (2438mm) using SmartWorks Touch software (included). The Colortrac SmartLF SC 42 Xpress has a maximum of 50,400 pixels.

Colortrac SmartLF SC Xpress Series incorporates propriety technologies unique to Colortrac scanners. These technologies include SingleSensor, ClearView, SureDrive, Firefly and WinSync. Colortrac’s SingleSensor scanning is a patented technology which combines contact image sensors (CIS) in a robust, single-piece unit, enabling a significantly higher optical quality and dramatically increasing pixel alignment stability. The SmartLF SC Xpress Series has 30,000 short image-path sensors and a custom designed advanced bi-directional LED lighting system. The bi-directional lighting system, called ClearView, combines 96 to 144 extra long-life switchable red/green/blue LEDs across the full width of the scanner for optimum illumination and instant-on scanning capability. SingleSensor and ClearView work together to reduce optical errors to a minimum ensuring all scan and copy data is of the highest possible colour and dimensional accuracy. Because each sensor is on the same imaging line combined with bright, even light from the LEDs across the full width of the scanner, scans have a wide and consistent colour gamut across the full width of the document. Colortrac’s SingleSensor is colour calibrated and has a scan accuracy of +/-0.1% +/-1 pixel.

Colortrac’s SureDrive system is an innovative active pressure roller that gently presses the document against the SingleSensor. The single, full-width, motor-driven hold -up roller eliminates variations in document speed or feed inconsistencies, eliminating the possibility of misaligned data. The soft pressure roller running the full length of the SingleSensor allows the scanner to dynamically respond and actively work against the optical disturbances caused by document lift and paper creasing. Shadow effects in folds of creased documents are also reduced. This technology ensures that delicate or fragile media such as newspapers and old blueprints can be safely and accurately scanned without problem. WinSync means the Colortrac Smart LF SC Xpress Series is compatible with Windows 10, 8, 7, and Vista.

Colortrac’s Firefly technology refers to the new SuperSpeed USB 3.0 and optimised USB2.0 interface. The SmartLF SC Xpress Series scanners are the first to incorporate the new SuperSpeed USB 3.0 digital interface. With a dramatic x10 increase in 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 65-85MB/sec for USB 3.0. SuperSpeed USB 3.0 is unique to Colortrac and allows the SmartLF SC Xpress Series to work at full speed using higher resolutions on wider documents. The SmartLF SC Xpress Series has enhanced USB2 circuitry which achieves a 25% improvement in data speed (35MB/sec) above the previously recognised industry average transfer rate of 28 MB/sec for a normal USB2 equipped PC. Higher data transfer give the SmartLF SC Xpress Series user the freedom to scan wider and at higher resolutions without compromising productivity, making it ideal for large amounts of archiving.

Optional accessories for the Colortrac SmartLF SC Xpress Series include: a Document Return Guide, for retrieving scanned documents to the front; Floor Stand with Catch Basket; PC, Monitor, Keyboard and Mouse Mounting Kit for Floor Stand; Repo Stand; and Document Carrier Sheets.

As you would expect from Colortrac, reliable performance is a given. For added peace of mind, Colortrac SmartLF SC Xpress Series wide format scanners feature a 2 year next day on-site warranty.
