ScanFile User Guide
DR-2580C
Please note that when this option is used, only the area of the document
inside the box will be saved. All other parts of the scanned document will be
discarded.
Adjust
The Adjust option sets the scanner to automatically detect the size of each
page scanned, and will adjust the page size to the actual size of the
document. When this is set, the Page Size option is disabled
Skew Correction
This function is a software driver based skew correction facility that can be
selected by a checkbox on the main Scanner Setup window. Should pages
be scanned at an angle through the scanner, and not appear straight when
viewing, this option will straighten the page and justify it which will help when
performing other actions such as OCR.
Resolution
You can select one of the following: 100, 150, 200, 240, 300, 400 & 600dpi
Compression
The type of compression and file format you select is dependent upon
several factors including the type of document to be scanned, and the type of
output required of that document once stored.
Uncompressed TIFF:
This format will perform no compression on the image data produced from
the scanned document, and will result in large file sizes.
Group 4 Compressed TIFF:
This format will compress the scanned image data, normally by a factor of 10
to 15. This is only used for black & white scanned images. This is a 'lossless'
compression format which means that none of the original scanned
information is discarded.
JPEG (JTIFF):
JPEG is a standardised image compression mechanism, which is designed
for compressing either full-colour or grey-scale images of natural, real-world
scenes. Jpeg is a 'lossy' compression format, which means that data is
discarded from the original scanned image data to achieve the levels of
compression possible. It is possible to vary the amount of data to be
discarded, and therefore the quality of the remaining image. ScanFile has
various quality levels for Jpeg images which will determine how much data is
