Maintaining the projector lens: thoroughly remove dust from the projector lens surfaceⅡ
April 07, 2022The second step of projector maintenance-wipe off the dirt on the surface of the projector lens.
The wiping tools are alcohol and cleaning paper. Of course, for ordinary users, alcohol can be replaced with Erguotou, etc., but it is best to wipe the mirror paper, because ordinary paper towels are mixed with some large particles of impurities, easy Scratch the lens. When we go to buy glasses, the clerk will also remind that paper towels can easily scratch the glasses.
The tools for wiping are alcohol and cleaning paper
How to wipe next? Use a folded mirror paper stick and wipe it with alcohol. So first let ’s take a look at how to fold the mirror paper. As shown in the figure, fold the audition paper into a thick paper stick. The reason for this is to use its elasticity to glide on the lens surface to take away the dust, rather than pressing it on the lens surface by hand to wipe it back and forth.
Origami method
Netizens, please note that you can't rub the paper or cloth on the lens like we wipe the glasses. Carefully observe that most of the glasses are scratched, but we may not feel it. The scratches on the lens of the projector, when projected on the screen and magnified n times, have a very strong impact on the image quality.
Clean the lens
So wipe the audition paper in the same direction. After wiping it once, place the audition paper on the edge of the lens to take away the dust. It cannot be wiped back and forth, so the dust is brought back to the lens. After wiping the surface in sequence, cleaning the projector lens surface is complete.
Tips: According to the different degree of lens dust, the frequency of changing the test paper is different. If dust has adhered to the paper stick, it needs to be replaced to avoid grinding. If the lens is very dirty, you can wipe it lightly to remove particles and dust, and then repeat it again to completely remove the dust on the surface of the projector lens.
