The scanner is an important digital device. Its remarkable feature is that the scanned image will not be deformed, and the scanner can obtain extremely high resolution. This is a digital camera, a high-photographer, etc. Not as good as the comparative advantage. However, many readers do not know how to use the scanner. Some users have scanners and do not know the detailed application methods. This article describes how to use the scanner: If it is a separate scanner, it is important to point out that the new scanner, in order to prevent damage to important photosensitive devices during transportation, has a photoreceptor lock that must be unlocked before use. Otherwise, when the motor drives the exposed part, it may be damaged due to locking. After the scanner driver is properly installed, we will find the corresponding program in the start menu. The author of this article uses the scanning function of the HP 4625 all-in-one, and the software that is launched is relatively independent. For some specialized flatbed scanners, there are more complicated options, such as whether the depth of the selected color is 8-bit color or 16-bit color, whether to remove the printed texture, whether to remove the yellowing of the photo, and the like. The resolution of the scan is the most critical option. A4 size scan, even 300dpi, the generated file is already large enough, unless it is scanning the film, it is easy to scan with a resolution of 1200dpi or more, otherwise it will not only take a long time, but also the file size will be very large. The file save type is a matter to be aware of. If it is only a problem to solve the image, then scan it into a .jpg image. If you are scanning photos or negatives and want to further processing, it is best to save them in .tiff format, because this is a lossless image format, although it is bulky, it will not be compressed, and it can save more color information. .
