Scanner performance parameters

When choosing a scanner, first look at the performance parameters, including scanning width (size), optical resolution (mostly positioned at 600x1200 dpi and higher), a color digit (the higher the digit is, the richer the color is), and photosensitive elements (CCD technology is currently the most mature one, with superior performance, while CIS is suitable for a mobile office environment).

This is too easy to understand because LED is expensive! The 100-inch Sony TV has already sold for 500,000 yuan! At present, with the increase in LED size, the price has doubled. If the LED is put into cinemas and made into a length of more than 10 meters, the cost is unimaginable. If the LED screen is damaged, artificially damaged, etc., these will cost an arm and a leg.

Using a projector is usually called watching a movie, will using an LED screen watching TV. What if con...

What is a high-speed camera scanner? A high-speed camera is a kind of equipment used in educational institutions, which can be used for preparing lessons. A high-speed camera is a piece of ultra-portable office equipment, which belongs to low-carbon office equipment. The high-speed camera can be used to scan characters and images and can convert pictures and texts. The camer...

High-speed camera scanner is a hot office product in recent years. It can not only be used for photographing, video recording, photocopying and faxing, but also has a smaller size, which is convenient to carry and is more perfect in function compared with traditional scanners. It can be said to be a perfect solution to make the office easier, faster, and environmentally frie...

As a high-tech product integrating photoelectricity and machinery, the scanner has become a necessary electrical appliance for daily office and life due to its unique digital "image" acquisition capability, low price, and excellent performance. Scanners can be divided into platform type/flat plate type, drum type, portable type, high speed camera scanner, ...

1. Unplug the power socket or turn off the power when it doesn't cool down

As we all know, heat is the killer of projection light bulb, which is the reason why many manufacturers have repeatedly stressed the effect of heat dissipation. After the projector is turned off, it is better to cool it down for a while. The airtight design of the projector is difficult to automatically dissipate heat. After unplugging the power supply, the projection fan will stop working immediately. As a resul...

When you choose a professional non-contact smart book scanner, you need to know what is the key factor.

Extra-curricular books, textbooks, magazines, and historical documents have different colors, shapes, and sizes. For libraries, archives, and museums, the digitization needs of historical data are facing greater challenges. When establishing and investing ...

Do you pay attention to the precise information of every detail or just take a rough understanding?

To evaluate the quality of professional scanners, image resolution is the key factor. Resolution is a key indicator of the scanner's ability to reproduce accurately or roughly. The higher the resolution is, the more accurate the details and levels collected from the original file will be.

Comparing the two types of CCD scanning systems, the real resolution is very impor...

Scanners can convert written materials or physical objects such as pictures, photos, films, and manuscripts that want to be saved into pictures or PDF format and input them into computers. They are important equipment for paperless work. So how to install the scanner? There are different types of scanners and different methods of installation. Let's take a look at the installation procedures of the three types of scanners.

Working Principle of Scanner: Currently, the working principle of desktop scanner is divided into two types: CCD and CIS. CIS products work like fax machines. They have no lens components, and use light emitting diodes as light sources and diode photosensitive elements. Because of its simple and compact structure, the volume can be made very small. The thickness of CIS products is usually less than half that of CCD products. However, CIS devices have no lens imaging part, so the depth of fiel...
