Congratulations on your purchase of the
Scantron iNSIGHT 20 Plus Scanner. This
scanner represents the latest in document
handling and scanning technology.
The iNSIGHT 20 Plus scanner can perform
both data collection and document imaging
tasks. The following two sections describe the
differences between these tasks.
Data Collection Data collection is the process of reading marks from
printed forms (e.g. surveys, tests, ballots, etc.) and
converting them to ASCII data. The iNSIGHT 20 Plus
scanner precisely scans the sheets for data while your data
collection software (for example, ScanTools Plus) controls
the scanning process and stores the data that is read. The

scanner and software work together to read up to 1950
sheets per hour in data collection mode.
The types of data that can be read include written marks
(bubbles, check marks, or tick marks) and software bar
codes. The iNSIGHT 20 Plus scanner with ScanTools
Plus software can also scan grayscale images for digital
storage. In addition, the iNSIGHT 20 Plus can read
machine print and handprint using RealTime Character
Recognition software (available separately).
Document Imaging Document imaging is the process of scanning and
processing black & white, grayscale, or color images. A
common use of document imaging is digitally storing
documents such as student work, patient records, invoices,
photographs, and more.
The iNSIGHT 20 Plus scanner can effectively transport
sheets of multiple sizes and thicknesses in a single load.
The images are scanned and then processed using the
included Click&Scan software. Using Click&Scan
software, you can select the format of the scanned image
(black & white, grayscale, or color), the resolution, the file
type of the stored image, and the destination of the
resulting file.
In document imaging mode, the iNSIGHT 20 Plus
scanner with Click&Scan software can scan up to 1950
two-sided, color, 200 and 300 dpi images per hour.
