Scanners are used to scan images and documents to turn them into soft copies. Scanners are also a type of office equipment that has evolved significantly from their early days when they were large and could only do one thing. Today, they are essential tools in various industries, making tasks easier, boosting productivity, and helping preserve important documents. In Bangladesh, whether you're a professional seeking a top-quality scanner or a casual user hoping to use it for personal work, Star Tech can help you purchase the right scanner or more specifically document and image scanner according to your needs, preferences, and budget in BD.
Some of the market-leading manufacturers' best image scanners you will be able to find on Star Tech’s website. Here, you can find regular scanners along with image scanners online of top brands such as HP, Canon, Epson, Plustek, Brother, Mustek, and Avision in Bangladesh. All these brands have diverse image scanners with various features that aim to make necessary images or documents more accessible to you.
Before buying a document or image scanner., you should thoroughly know the following distinctive features of Scanners. After that, you will be able to decide more rationally which scanner is best according to your use and preferences.
Scanners’ resolution is measured through dpi (dots per minute). Usually, scanners start with a minimum resolution of 300 dpi and can go above 5000 dpi. Star Tech has scanners with a minimum resolution of 600 dpi and has some flatbed scanners with scanning capabilities above 5000 dpi. The higher the resolution, the more high-end detailed image.
Scanners along with image scanners can connect to computers and devices through various means, including USB, wireless (Wi-Fi or Bluetooth), network, and cloud connectivity. Specialized scanners may use proprietary interfaces. The choice of connectivity depends on the scanner's intended use and compatibility with target devices and software.
A regular scanner operates between 20 to 40 ppm. However, high-functioning scanners may go over 140 pages per minute. Document scanners have different speed limits for different modes of pages. For instance, the scanning speed for BNW or grayscale pages is 25-60 ppm, and for colored pages is 25-40 ppm. Sheet-fed, a type of document scanner can range around 20 to 100 ppm depending on the brand and model.
The color depth of document scanners or image scanners is measured in bits per pixel (bpp). It determines the scanner’s quality and ability to reproduce colors accurately and the level of detailed grayscale images. The original or ‘true color’ is represented as 24-bit color depth and 48-bit provides even greater color accuracy. However, the 1-bit represents only two colors- black and white and the 8-bit color represents 256 colors or shades of gray. The higher the color depth, the more accurately and finely the scanner can reproduce colors and shades.
There are various types of scanners, including flatbed scanners, sheet-fed scanners, document scanners, handheld scanners, and 3D scanners. Each type serves specific purposes, from digitizing photos to scanning large volumes of documents.
Barcode Scanners transform images to alphanumeric digits by recoding or translating the images. These image scanners are used to send information about certain products or something along to a computer database through a Wi-Fi or broadband connection. Additionally, a QR scanner is simply a scanner that scans QR codes. Some devices like the Apple iPad have a QR code reader with a built-in camera. Both barcode scanner and OR scanner scan as well as read QR or barcodes which includes URL, product contact, calendar, email, location, text, and many more formats. On the contrary, various businesses, especially e-commerce-based ones, use barcodes or QR scanners to keep a record of their products.
Flatbed Scanners are the most widely used scanners of all time. These scanners are popular for their scanning capabilities on a flat surface. These scanners can also handle documents of different sizes and are typically more versatile compared to sheetfed scanners.
Sheet-fed scanners are a type of document scanner designed for efficiently digitizing a large number of documents, typically in the form of loose sheets or pages. These scanners are widely used in office environments and document management systems for their speed and automation capabilities.
Handheld scanners are portable devices designed to capture images or data from the physical world and convert them into digital format. These scanners are lightweight, compact, and easy to operate, making them versatile tools for a wide range of applications.
3D Scanners are capable of capturing shapes, dimensions, and colors of physical objects to convert them into digital 3D models. They use various technologies, such as laser, structured light, or photogrammetry, to collect data points from the object's surface and create a digital representation. These 3D models can be used for various purposes, including 3D printing, reverse engineering, quality control, and digital preservation.
While scanners and printers are often components of a multifunction device known as a "multifunction printer" (MFP) or "all-in-one printer," these functions are separate within the device. In other words, you can't directly use a standalone image scanner to produce a printed document; you would need a printer for that purpose. However, an MFP, which combines scanning, printing, copying, and sometimes faxing functions in a single device, allows users to both scan and print documents using the same machine. However, these functions are still separate and require specific actions, such as selecting "scan" to scan a document or "print" to print a digital document, within the MFP's interface.
