Document Scanners

By definition, a document scanner converts a hardcopy document to their digital form. There is a wide range of document scanners, each document scanner having their own purposes, some of which are meant for scanning cheques, books, passport as well as wide format.

Importance of Document Scanners

An advantage of a document scanner is that they are mostly light and mobile as compared to multi-functional printers (MFP). A document scanner is also better at scanning as compared to a MFP. Despite the fact that a MFP can scan both sides at a time, a document scanner can do it better at a higher resolution. A document scanner would also be chosen when it comes to doing specific scanning such as scanning of books, cheques, business cards etc. This is because there are document scanners made to specialize in such task that just cannot be accomplished at the same level using a MFP.

Understanding the Specifications of a Document Scanner

Scanning Resolution – The output resolution of a document scanner is based on its DPI (dots per inches). The higher the DPI, means the better the image would turn out.

Scanning Speed –  Each document scanner has different scanning speed. Mostly, they would be based on the number of pages a document scanner is able to scan per minute. Whereas, if the document scanner has no feeder, it would be based on the time it takes to scan a page.

Feeder Capacity – The feeder capacity of a document scanner is based on how many sheets of paper it can hold at a time. However, some document scanners would not have a feeder capacity as it does not have a feeder, meaning the user would have to replace the documents manually.

Daily Volume – The daily volume of a document scanner refers to the number of pages it can scan in a day.

Document size – The document size refers to the maximum size of the document the scanner can scan.

How to choose your document scanner

Finding the right document scanner can be tough, regardless if it is your first time or you are getting an upgrade. As there are many different types of purpose to a document scanner, knowing your requirements exactly would allow you to find the scanner that suits your needs.

One of the simplest methods would be to base it on the volume of scanning done by you on a daily basis and compare it to the daily volume of a scanner.

Next, would be to base off the speed of the scanning you require. If you do not mind a slower speed and are at a tight budget, Avision would be suitable for you. However, if you require a higher speed, Canon would be more suited for you.
