How Do You Know What Is the Best Scanner?
If you are interested in purchasing scanners, you may be wondering what the best scanner for the office is. Some people prefer models that do more than just scan documents. Others like to use scanners for photo or document protection. When it comes to purchasing scanners, there are a few things that you should consider. First of all, you need to think about how often you scan documents and images in your office.
There are two basic kinds of scanners. One works by using a laser to send an image or text file across a connection to a computer. The other uses an adaptor that takes a picture and transmits it over a regular network, such as a network of wires, to a scanner. These two basic types of scanners have their advantages, so the choice usually comes down to which one you want for your office.
Most commercial scanners today are available with a flatbed design. A flatbed scanner scans documents without a paper sheet. The document is placed on a special sensor that “reads” the document and compresses the image into a protective sheet. Since the document is flat, the original form is not lost during the scanning process. The flatbed scanner produces top quality scans that are great for scanning many types of papers.
Some scanners can also scan photographs. These scanners use an optical engine to transfer the image from the camera up to the scanner, then convert the image into a readable, file format. This type of scanner can scan many types of digital photographs, including slides, negatives, and prints, but the cost of buying multiple units to scan different pictures tends to be expensive.
Some scanners, however, can do both scanning and conversion of digital images. A scanner that only scans one document at a time is known as an adf/ duplex unit. Duplexing units combine scanning and conversion capabilities, so two copies of a document can be taken with one unit. This is useful for situations where one copy may be damaged, incomplete, or otherwise difficult to read.
The final type of scanner is a sheet feeder unit. Like the adf/duplex, a sheet feeder unit combines scanning and conversion capabilities. This type of unit takes an original document, scans it, and then imprints a new sheet of paper onto the scanner. The new document is then read by the scanner and its contents are converted to a text file.
These are the basic types of scanners. Each one has its own strengths and weaknesses. Your choice will depend on your needs, what you will be scanning, how much you have to scan, and the price you’re willing to pay. The most important thing to consider when buying a scanning equipment is whether or not it will do both scanning and conversion.
With the flatbed scanner, you take a photo with a normal film camera and convert it to a Tagged PDF with your computer. Then the sheet feeder equipment takes the original document and converts it to a Tagged PDF. You will probably want both types of scanners, so that you can scan many different kinds of originals. Many people still use the simple adf/duplexer because they don’t like to spend time converting their originals. The point is to get the best out of your money. You will find that as long as you don’t spend too much on your scanning equipment, which you shouldn’t, your results will be worth it.
The next step up from a simple adf/duplexer are scanners that can do both scanning and conversion. There are also some that have the option of both, but have a tendency to only do one or the other. If you’re going to spend the money on a scanner that will do both, you should be sure to get a scanner that will work for you, since the first one you buy may not be the best for your requirements.
Many scanners can actually be set up to scan in “both” ways. For example, there are scanners that can scan and convert as well as print. These will probably be the most expensive scanners, since they offer quite a bit more functionality than a simple adf/duplexer. But if you need to scan lots of originals, you really don’t want to compromise. Some of these scanners will offer both at the same time.
Some companies offer single units that will scan and then copy it to DVD. These are usually great for people who transfer a lot of original documents. Others will allow you to scan one document and then have the convert to PDF function done on the fly. These are usually the cheapest units available. The best scanner is one that will serve all your needs, without any sacrifice to usability.
