Document Scanning Equipment
Your choice of Document scanning equipment is based on two important
factors - Scanning requirements and budget.
Unlike 6-7 years ago today there are many document scanners to
chose from, all producing exceptional quality and come with a variety
of features.
When deciding on a scanner consider:
1) Space - how much room do you have or your scanner. Some scanners
are far larger than people imagine and can take up a great deal
of room.
2) Type of documents. Decide what type of documents you will be
scanning. Will these all be A4 lose pages or will you.
3) Black White / Colour -
4) How many documents will you be scanning per day/week. There is
little point in spending huge amounts of money on a scanner if you
are only scanning 100 pages per day.
5) Budget - What is your budget?
Think of ongoing costs to. Maintenance and parts are often forgotten.
All produce a full range of different scanners to fit any requirements,
from flatbed scanners for books and difficult to scan documents,
to ADF Scanners (Auto document Feed) scanners for high volume fast
scanning which will allow you to scan hundreds or several thousands
documents per day.
Flatbed Scanners
Flatbed scanners are designed for books and large delicate documents.
The flatbed allows you to open the top of the scanner and place
the document face down directly on the glass.
Flatbeds are extremely popular because of the control they give
you over the placing of the document.
Flatbeds are generally the most costs effective of scanners because
they don't have the added expense of the complex rollers and feeders
of the ADF unit

* Delicate documents.
* Books and bound pages can be laid flat without having to separate
or remove its binding.
ADF Scanners
ADF Scanners are designed for documents, which will feed through
the scanner. This allows you to scan many hundreds of pages automatically
with little user intervention
Documents are simply placed in a stack on the document scanners
feeder tray documents are then drawn in the scanner automatically
by a series of rollers.
ADF are more expensive due to the mechanical differences over a
flatbed

* High volume scanning.
* The documents must be suitable for the Feeder.
ADF & Flatbed
Some scanners such as the ones shown below from Epson and Bell
and Howell can operate both as a flatbed and an ADF, which provides
the user with the best of both worlds.
On the top they have the ADF (Auto Document Feeder) facility whilst
they also open up allow the user to place documents directly on
the scanner glass for flat bed scanning of books and more difficult
documents which will not feed through the ADF
These are ideal where the user has a mixture of document types.
