PDF Scan Kit benefits

The standard Xerox 4112/4127 C/P built-in Scan feature allows you to scan to folder, email,
FTP/SMB, and other locations with standard scan settings. These standard scan settings enable
high resolution scanning, which in turn creates a larger PDF file size. You can use lower
resolution scans to minimize file size, but the scan quality can be impacted. The PDF Scan Kit
enables more advanced compression technologies, such as MRC, JBIG2, MMR and MH that
allow you to create compressed, high-quality files.
The PDF Scan Kit includes the following features, which are described in detail later in this
section:
• MRC High Compression scanning
• Searchable Text
The PDF Scan Kit can be used with the following services: Scan to PC, Email and Network
Scanning. An example of using each service with the PDF Scan Kit is presented later in this
document.

Compression Scanning

Large files take up more storage space and take more time to transmit than compressed PDF
files. There are numerous benefits to compressing files to PDF, but some of the most important
benefits are:
• Compressed PDFs can be sent up to 10x faster than files that are not compressed.
• Compressed PDF files take up much less storage space on your system.
• When transferring compressed PDF files over the Internet or Intranet, you use less
bandwidth.
When using the PDF Scan Kit, you have access to the following compression models:
• MRC High Compression: This feature, specific to the PDF Scan Kit, enables you to create
high resolution, high quality compressed scans that allow for fast and efficient transport
through networks without impacting the scanned image quality. For additional
information, see; MRC High Compression Scanning
The following compression models apply to Black and White images, only. They are available
when using the standard scan package as well as with the PDF Scan Kit.
• MH: Modified Huffman - (CCITT-G3) Lossless Fax compression for binary Black and White
images, only. For Black & White pages, MH is used when Photo is selected as the Original
Type.
• MMR: Modified Modified Read - (CCITT-G4) Lossless Fax compression for binary Black and
White images, only. This is the default setting for Black and White jobs.
• JBIG2: Joint Binary Image Group v2 - The most recent replacement for the CCITT-G3/G4
binary Black and White lossless compression schemes. A scanned image can be compressed
up to 10x smaller than with TIFF G4 (MMR). There are two sub categories:
• JBIG2-Arithmetic: Arithmetic coding is a method of encoding data using a variable
number of bits. The number of bits used to encode each symbol varies according to the
probability assigned to that symbol.
• JBIG2-Huffman: An extremely popular compression method for text-based data.
Huffman coding uses an integral number of bits to encode a symbol.
