For the two questions about the scanner, thank you for another 100 extra points

First, update the driver of the scanner in the device manager, if it is invalid, go to the **on** of Founder Technology**a F series 5600 driver with your 4280 driver.

Second, clean your scanner and you'll be able to solve the problem.

Introduction: For many users who are facing the purchase, how to better choose a scanner, what is the development trend of the scanner, whether the technology of the scanner is mature, etc., all need to be considered and figured out, therefore, this article aims to explain the development history and classic models of the scanner, and recommend the current hot-selling models, so as to facilitate everyone's purchase.

1.When the scanner switch is turned on, the scanner makes an unusual noise.

This is because some models of scanners have locks that are designed to lock the lens group and prevent vibration during transport, so the lock should be turned on before turning on the scanner power switch.

2.The scanner didn't respond when it was powered on.

Some models of scanners are energy-efficient, and the light tube will only light up when entering the scanning interface, and will automatically turn off once exited.

3."Scanner not found" is displayed when scanning.

This phenomenon may be caused by turning on the host first and then the scanner, so you can restart the computer or refresh it in Device Management.

4.Is the resolution of a scanner the same as the resolution of a printer? How should I choose a printer based on the resolution of the scanner?

The unit of resolution of a scanner should be strictly defined as ppi, not the number of pixels per inch, and for a scanner, each pixel is not a simple description of 0 or 1, but a description of 24 bits, 36 bits, or CMYK (1004). The D in the dpi of the printer's resolution refers to the dot in English, and each dot has no depth, just the concept of 0 or 1, and for the scanner, 1 pixel needs several 4 dots (CMYK) to describe, that is, the color of a point is determined by the density of different dots. So the DPI concept of a scanner is different from that of a printer.

Use a 1440dpi printer to output a 1:l image, and scan with a scan of about 100-150dpi.

5.When the scanner scans, there is a prompt saying "There is not enough space on the hard disk or not enough memory".

First of all, make sure that the hard disk and memory are sufficient, if the space is large, please check whether the scanning resolution you set is too large and the file data is too large.

6.The scan makes a lot of noise.

Open the lid of the machine, find some sewing machine oil drops on the toilet paper to wipe off the grease on the two tracks of the mirror group, and then drop the sewing machine oil on the transmission gear set and the bearings at both ends of the belt (pay attention to the appropriate amount of oil), and finally adjust the tightness of the belt appropriately.

7.The scanning time is too long.

Check the remaining capacity of the hard drive, optimize the hard disk space, delete the useless tmp files first, make scandisk, and then do defrag or speed disk. Please note: It is normal for the scan to be slower if the final actual scan resolution is set to be higher than the optical resolution of the scanner.

Disadvantages: The scanning speed of the book is too slow (the high-speed scanner can't scan the bound book), and the speed is generally 10 to 20 seconds.

Suggestion: If there are more books scanned (more than 1000 pages), it is recommended that you buy a high-speed camera, there are many brands on the market for you to choose from, and the product within 1000 yuan can meet your use, the advantage is that the speed is fast 1 3 seconds, and text recognition can also be realized; The downside is that if you use it to scan**, the effect is not as good as a scanner. If there are few books (less than 1000 pages), it is enough to buy a 300 500 scanner.

Scanning on the outside should be calculated according to the thickness of your book, usually about one page.

Generally, I use a flatbed scanner, but what are the disadvantages, format limitations, speed, and scanning books, a word is tired.

Scanning books** is generally not lower than the book price, probably 3 15 or even higher times the price of the book, completely depending on the content and the standard you want to achieve.
