Cleaning the lens surface of the projector
Cleaning the projector lens is mainly divided into two steps: first, blowing off the surface dust, and second, wiping off the stain on the lens surface. However, if it is not handled properly, it is easy to cause many scratches like glasses and reduce the image quality. Let's take a look at the image and see how to clean the lens surface of the projector.
Projector lens maintenance first step - blow off the dust on the surface of the projector lens.
The dust on the surface of the projector lens is usually large. If it is directly wiped, the particles will grind the surface of the lens and it is easy to scratch the surface of the lens. There are usually three ways to blow off the dust on the surface of the projector lens:
Cleaning surface dust
Use a professional projector dust removal tool - air gun, high pressure gas supplied by air pump; use blow air balloon, like the master of repairing the watch, blow it down; for ordinary users, when there is no special tool, it is also used to blow directly with the mouth. Yes. However, it is okay to pay attention to the number of units. If there are more projectors, it may cause hypoxia. In all three methods, the tool does not touch the lens surface, so it will avoid the scratching of the lens surface by large particles of dust.
Projector Care Step 2 - Wipe off the stain on the surface of the projector lens.
The tools to be wiped are alcohol and wiped paper. Of course, for ordinary users, alcohol can be replaced by Erguotou, but it is better to wipe the paper, because ordinary paper towels are mixed with some large particles of impurities. Scratch the lens. When we go to buy glasses, the clerk will also remind that the paper towel is easy to scratch the glasses.
Wiping tools are alcohol and wipe paper
How to wipe next? Use a folded audition paper stick and rub it with alcohol. So first let's take a look at how to fold the mirror paper. As shown in the figure, the audition paper is folded into a thick paper stick. The reason for this is to use its elasticity to slide on the surface of the lens and take away the dust instead of pressing it back and forth on the lens surface.
Origami method
You netizens should pay attention not to rub the glasses or cloth on the lens back and forth like us, and carefully observe that most of the scratches on the glasses are scratched, but we may not feel it. The scratches on the projector lens, after being magnified n times on the screen, have a great impact on the picture quality.
Cleaning lens
So wipe the test paper in the same direction. After the wipe is finished, place the test paper on the edge of the lens to remove the dust. Instead of rubbing back and forth, the dust is brought back to the lens. After the surface is wiped in sequence, the lens surface of the projector is cleaned.
Tip: According to the degree of lens dust, the frequency of changing the lens paper is different. If the paper stick has been attached with dust, it needs to be replaced to avoid grinding. If the lens is dirty, you can wipe it off first, remove the dust from the particles, and repeat it again to completely remove the dust from the lens surface of the projector.
