How to protect the scanner so that the output of the screen more clearly

In recent years scanners have been used as a common input device, with its price drop, now has been accepted by many families, scanners are a very fine equipment, sometimes our scanner scan out of the screen effect is not too good, some blurred picture, and the output of the image color is not gorgeous, do not know why?

First look at the scanner plate glass is not dust, if it is the glass with a clean cloth or paper wipe clean, but be careful not to use the liquid containing alcohol to rub. Then check to see if the scanner uses the correct resolution, number of colors, and so on. If you are scanning print, also pay attention to the grid settings. The color of the image is not bright enough, it may be related to the unreasonable software settings, such as the gamma value set. (Gamma is a sensory curve from the dark tones to the bright tones of the human eye.) The higher the gamma value, the richer the level of the sensory color. We can adjust the gamma value according to the specific situation of the scanned photos. For general purposes, gamma is usually set to 1.4, if used for printing, set to 1.8, and the picture on the Web page set to 2.2. There is the scanner should be used before the color correction, otherwise it is very likely to distort the image scanned; In addition, you can specifically adjust the brightness/contrast options in the Scanner driver dialog box.

For a rainy day, we should regularly do maintenance work, because usually if the scanner in the flat glass, reflector or lens on the fall of dust or some other impurities, will make the reflection of the scanner light weakened, and therefore affect the quality of the scan. So we should be as far as possible in the dust-free or dust as little as possible in the environment to use, and after use, to use a dust cover to cover the scanner. However, because of the conditions we are generally not likely to use in the dust-free environment, so we have to develop the habit of regular cleaning.

First we have a soft cloth to wipe the scanner's shell, the purpose is to sweep the surface of the dust, to prevent the use of water when wiping the shell to spend. Then we use a wet cloth to wipe the shell carefully again, but note that the cloth should not be too wet, and in the process of wiping it is best not to have water out, to prevent the damage to the inside of the machine into the circuit. In some places where the scales are thicker, you can dip some detergent on the wet cloth or washing powder, and then rub a few times on it, and finally do not forget to use a clean wet cloth to wipe with detergent or washing powder to wipe the place again, lest residual detergent or washing powder caused the shell discoloration.

Next to open the scanner's shell, if found inside the dust is thicker, you can blow the balloon blowing, do not forget in this period of the scanner with the cover up, otherwise we just did it white. If you have a vacuum cleaner, it will be better to vacuum it. Then we find the scanner's light-emitting tube, reflector, take a dip in the water absorbent cotton, wet and dry degree to squeeze after not water can be. Then carefully in the light-emitting tube and mirror on the wipe, wipe the attention of the action must be light, do not change the location of optical accessories.

If you find that the scanner in the process of moving some noise, it is likely that the slide rod oil or on the surface of the scale, you can apply some lubricating oil on the slider, increase its lubrication, noise problem can be solved.

When the inside is fully cleaned, the scanner is installed. Finally, we are cleaning the flat glass, because the panel is clean directly related to the image of the scanning quality, so we clean the panel, first with a glass cleanser to wipe it again, and then use a soft dry cloth to wipe it clean, Then you'll be amazed to find that your scanners are not as different as when you first bought them, and you can enjoy the fun of scanning.
