There are several scanner models on the market, designed for all pockets and user profiles. To choose the ideal scanner model for you it is necessary, first of all, to define the intentions of using the product.

If you need a scanner for high-precision scanning, such as photos and images, you should focus on high-resolution products.

If you want a device only for sporadic scans, without levels of excellence in resolution, consider a multifunctional model, which adds the printer and copier functions to the scanner.

This model may be more advantageous for delivering more features than a device with the unique function of scanning, and with excellent cost benefit.

If the intention is portability and practicality, choose portable or handheld models. Check the model’s power supply. Some work without cables and without the need for a computer or notebook, which can be extremely useful for those who perform external services, for use in libraries, travel, etc.

Now, if you need a device capable of scanning many pages at once, choose sheet-fed flatbed models.

Fast and intuitive, they do not need to feed from sheet to sheet, making them ideal for offices, schools or places that need to handle large volumes of paper frequently.

Regardless of the models chosen, there are points common to all equipment that it is essential to pay attention to.

Carefully check the reputation of the appliance brand. Make sure that services such as technical assistance and spare parts are available in your locality.

Be sure to check the device’s voltage and connection method to ensure compatibility with the location and equipment in use. Also, check the measurements and the size of the device, so that it fits the available space.

Another important point is the size of the power and connection cables. Make sure the cables are long enough to allow installation in the desired location without the use of extensions, which can increase the risk of shorts and damage the product.

Portable

It is ideal for those who need mobility, fast low volume scans. But the resolution may be lower than that of conventional models. Some models work with a rechargeable battery or battery. This model does not require connection to a computer.

Multifunctional

Ideal for home use as it adds functions such as printer, copier and fax. The scanning capacity varies by model. The multifunctional has a better cost-benefit ratio. Stay tuned as it must be connected to a computer.

Purchasing criteria: Factors for comparing the different scanner models

Now that you have a lot of general information about scanners, we will list some of the features that you can compare to recognize the best scanner option to meet your needs and expectations. Are they:

• Model
• Resolution
• Capacity
• Size

Model

As we mentioned earlier, the main scanner models are four: portable, sheet-feed, flatbed and multifunctional. In addition to the design and ways of functioning, these models differ in terms of usage and capacity.

Check the details of each model to define the one that best fits your needs.

• Portable : Compact size allows it to be taken anywhere, and does not require large installations for use. They can operate on battery or cell. It scans quickly, being ideal for those who perform external jobs and need to scan documents, in small quantities at a time.
• Sheet-fed table : They usually offer connection functions via bluetooth and wi-fi, making them ideal for offices and commercial environments. It has the capacity to scan large volumes of documents in sequence, without having to change or turn sheets.
• Flatbed table : With the ability to scan only one face at a time, this model usually has unbeatable resolutions. Because it is able to capture more details, it is ideal for those who work with images, photos and illustrations, or who need to scan with above average quality.
• Multifunctional : Ideal for those who want to save space and money, this model adds three or more functions in one device, usually a scanner, copier and printer. It is ideal for home or corporate use where scans are sporadic and there is no need for excellent resolution.

Resolution

Resolution is nothing more than the level of detail captured by the scanner. For this type of device, the unit of measurement used is dpi, which means dots per inch in English, and dots per inch in Portuguese. The higher the dpi of the model, the more detailed and clear the scan will be.

The most basic scanners generally have a resolution of 300 x 300 dpi, indicating values ​​for horizontal and vertical. These templates are ideal for scanning documents and books, as long as they are in good condition.

Papers with erased letters or old receipts can be impaired if they are scanned using low resolution equipment.

To scan photos, prints, illustrations or other types of material that you want to capture in rich detail, prefer models with higher dpi. Also note the interpolated resolution capability of the model.

Interpolation software is present in most of the more sophisticated models, and creates new points between the pixels of the optical resolution to further optimize the quality of the scan.

Capacity

Some scanner models are capable of scanning more than 50 sheets per cycle, while others are designed to scan only one side at a time.

Scanning a stack of processes, for example, can be a chore with inadequate equipment.

So keep in mind what your scanner’s usage profile will be, and check the manufacturer’s specifications to choose the model with the capacity that suits your needs.

Size

Even though they basically perform the same function, the scanner models can come in the most varied sizes, which can adapt to the different layouts of offices and workstations.

Some models, considering the reduced proportions of spaces today, offer an option for wall mounting, for example.

Portable models are also an option for those with little space. In addition, small-sized scanners have the advantage that they can be transported more easily, as they fit easily in briefcases, bags and backpacks. Some portable models are foldable to further reduce the space occupied.
