3 Factors To Consider When Buying A Scanner

Have you been considering buying a scanner for your home office? In today's digital age, a scanner can be an extremely important piece of equipment. Many companies prefer to receive documents in digital form via email. A scanner can help you convert your important paper documents to digital form. Also, a scanner can reduce your need for filing cabinets and other storage systems for paper documents. With a scanner, you can simply store all your digital documents either on your computer or in the cloud. You'll find many different types of scanners available. Here are a few things to consider as you choose your scanner:

Sensors

Scanners have sensors that pick up light while scanning a document. The quality of the sensor will have a direct impact on the quality of your scan. Higher quality sensors can often pick up more detail than lower quality sensors. However, higher quality sensors can also drive up the price of the scanner.

Generally, photomultiplier tube sensors can pick up the most detail. However, they can also be fairly expensive. The next best option that is also usually affordable is a scanner with a charge-coupled scanner device. They use bright light to help pick up text, images, and other items on the document.

Bit depth

A scanner's bit depth also determines how much detail it will pick up from a document. A bit is the smallest piece of information or data that a document or file can hold. Bit depth refers to the amount of bits that a scanner will pick up from each pixel on a document. Generally, the higher a scanner's bit depth, the more detail it will grab during a scan. Also, the higher the bit depth, the more the scanner will cost in most cases.

To find the right balance, consider the types of documents you'll be scanning. If they will be mostly text, you can probably get away with a lower bit depth. If you need to scan images, especially in color, you'll likely need a scanner with a very high bit depth.

Document feeding

Another important consideration is how you place documents in the scanner. A flatbed scanner is a popular scanner type in which you simply lift a lid and then lay the document face down on a glass tray. With a flatbed scanner, you can usually only scan one document at a time. Sheetfed scanners usually have a tray where you can load multiple documents. The tray will then feed the documents one at a time automatically. A sheetfed scanner can save you a lot of time if you frequently need to scan multiple documents.
