Scanners are highly versatile and can be used in various industries and situations. Since scanning technology is constantly evolving, they have both simple and highly complex applications. Let’s take a closer look at scanning technologies, as well as their uses and benefits.

Scanner Technologies and Operating Principles

Scanners work by using light sensors and optical systems to "read" images or texts from physical objects. They are most commonly used:

• Optical Sensors: These convert light from a document or object into digital signals. This may include CCD (Charge-Coupled Device) technology or CIS (Contact Image Sensor), which allows for the conversion of images into a digital format.
• Light Sources: Scanners use light sources (e.g., LED or halogen bulbs) to illuminate the document or object for image capture.
• Optical Resolution: This is the key indicator of scanner quality. A higher resolution provides more detailed images, which is important for tasks like professional photography scanning or medical imaging creation.

Types of Scanners and Applications

1. Document Scanners
These scanners are widely used in both offices and homes. They are designed to quickly and accurately digitize texts and documents such as contracts, books, or faxes. Document scanners are often equipped with an automatic document feeder (ADF), allowing multiple documents to be scanned at once.

• Application: Offices, libraries, archives, law practices, medical institutions.

2. Flatbed Scanners
These are the most common type of scanners, operating by placing the object to be scanned on a glass surface. The advantage of flatbed scanners is that they provide very high scanning quality by using light sources and sensors to capture highly detailed information.

• Application: Photograph scanning, books, drawings, business cards, contracts.

3. Photo Scanners
These scanners are specifically designed for digitizing photographs. They provide high resolution and can be used to convert old photographs or negatives into digital formats, preserving their colors and details.

• Application: Photo archiving, digital photo collections.

4. A0 Size Scanners and A4 Scanners

An A0 size scanner is especially suited for scanning large formats such as plans, maps, and artworks, while an A4 scanner is a common, everyday scanner designed for standard paper sizes. A0 size scanners provide scanning for very large and fine details.

• Application: Architecture, engineering, planning, artworks.

Why Use Scanners?

1. Efficiency: Scanners significantly speed up the process of saving and transferring information.
2. High Quality: Document scanners offer high resolution, which is crucial for preserving detailed images or texts.
3. Digital Archiving: Scanners allow documents to be stored digitally, helping prevent damage to paper documents and enabling quick access.
4. Instant Sharing: Digital images are quickly transferred via email or cloud storage.

The Future of Scanners and Latest Trends

The development of technology is making scanners more efficient and accessible. In the future, we can expect:

• The use of artificial intelligence in the scanning process to automatically recognize and categorize documents, improving workflow.
• Mobile scanners that can scan through smartphones or tablets using special apps and virtual elements.
• Scanners with higher resolutions, allowing even more accurate digital images.

What is DPI?

DPI (dots per inch) indicates how many dots are captured in one inch when scanning an image. A higher DPI means higher image resolution and precision.

• 150–300 DPI: Suitable for documents and texts.
• 600–1200 DPI: Ideal for photographs and medium quality.
• 2400 DPI and higher: Extremely detailed images, suitable for photo negatives and artworks.

What Can You Connect a Scanner To?

• USB cable – the most common connection to a computer.
• Wi-Fi – wireless connection to a computer or smart devices.
• Bluetooth – connection to smartphones and tablets.
• Ethernet – network connection, ideal for offices.
• SD cards or USB flash drives – storing scanned documents on external devices.
• Mobile device apps – direct communication with smart devices.

How to Scan a Document?

To scan a document, follow these steps:

1. Connect the scanner to your computer or other device (using USB, Wi-Fi, or Bluetooth).
2. Turn on the scanner and make sure it's properly connected.
3. Place the document on the scanner glass surface, aligning it according to the markings.
4. Choose a scanning program on your computer (such as Windows’ built-in "Windows Scan" or the scanner manufacturer’s software).
5. Select scanning settings (DPI, color mode, format, etc.).
6. Press "Scan" and wait for the document to be digitized.
7. Save the scanned file on your computer (format: PDF, JPEG, PNG, etc.).

Can the Scanner Scan Multiple Documents at Once?

Yes, some scanners can scan multiple documents at once using the Automatic Document Feeder (ADF). This feature allows you to place several documents (usually up to 20–50 pages, depending on the model) into a dedicated tray, and the scanner will automatically process them one by one.

How Does It Work?

1. Documents are placed in the ADF compartment.
2. The scanner automatically processes each page.
3. The scanned documents are saved either as separate files or as one combined document, depending on the settings.

What to Do if the Scanner Does Not Connect to the Computer?

If the scanner is not connecting to the computer:

1. Check the connection – ensure the cable or Wi-Fi is properly connected.
2. Restart the devices – turn off and then turn back on both the scanner and the computer.
3. Check drivers – make sure the latest scanner drivers are installed.
4. Check settings – ensure that the scanner is selected as the active device.

How to Save Scanned Documents in PDF Format?

To save scanned documents in PDF format, follow these steps:

1. Choose a scanning program (e.g., "Windows Scan", "Adobe Scan", or the scanner manufacturer’s software).
2. Place the document in the scanner.
3. Select PDF format:
◦ In the scanner software, look for the "Save As" or "Format" option.
◦ Choose PDF as the format.
4. Scan the document.
5. Save the PDF file to your chosen location on your computer or in cloud storage.

How to Use a Scanner with a Phone?

To use a scanner with a phone, follow these steps:

1. Download a scanning app: Get an app that supports your scanner, such as "Canon PRINT Inkjet/SELPHY", "HP Smart", "Epson iPrint", or other manufacturer apps.
2. Connect your phone to the scanner: If the scanner has Wi-Fi or Bluetooth, connect the phone to the scanner using the appropriate network or Bluetooth. If using a portable scanner, you may need a USB OTG cable or a special app.
3. Open the app: Launch the downloaded app and select the scanning option.
4. Scan the document: Place the document in the scanner and select scanning settings (color, resolution, etc.). Press "Scan" and wait for the document to be digitized.
5. Save or share the file: Save the scanned document on the phone, choosing the desired format (PDF, JPEG, etc.).
