What is a "document?"
A document can be from one to several thousand pages, and can include images and/or text, plus annotations.

Can I edit or alter images?
An imaging system should not provide any facility for editing or altering images. This is important because it preserves the integrity of the system. In addition, the system should provide an audit trail function to keep track of which users have accessed which documents at what times.

How much disk space does an imaging system typically require?
A single page typically occupies around 50KB of disk space if the image is stored in TIFF Group IV. Each gigabyte (GB) of storage space will hold approximately 20,000 pages. It costs much less to store documents on an imaging system than with paper.

What image resolution should I use?
Depending on the purpose and the contents of the page, most documents are scanned in black and white at 300 dpi.

What is OCR?
OCR stands for Optical Character Recognition, which is how a computer converts words in an unsearchable scanned image to searchable text. OCR is usually necessary in order to use full-text indexing and searches.

What is the difference between OCR and indexing?
OCR is the process of converting scanned images to text files. Full-text indexing is the process of taking a text file and adding each word to an index file that specifies the location of every word on every document.

How accurate is OCR?
Accuracy on a freshly laser-printed page is typically better than 99.6%. Accuracy on degraded documents will of course be lower.
