How To Remove the Dust in the Camera ?

With the living standards improve, digital camera / camcorder has become a common equipment of family life, but how many people know the correct maintenance of it?   

In fact, dust removal of digital electronic devices is a difficult issue for the user. Basicly manufacturers' after-sales service department can solve the problem, but the vast majority have to pay, whether you are security assurance inside or outside in the products. Faced with a lot of money about several hundred dollars asking price at every turn , many users had no choice but to retreat. Journalist ask a number of vendors' technical person about this question, summarized the main points of digital camera and other equipment dust removal as follows.   

Do not feel the parts easy to dirty first of all, pay attention to the problem on the maintenance at the beginning buy the camera, which can reduce the rate dust in bascily. Don't put the camera and the other electronic devices such as computer host together as possible as you can when it charging whitout a battery, otherwise easy to absorb substantial dust .   

In the environment have more dust should minimize the use of cameras, the directly exposed parts in camera such as lenses and LCD screens should be fitted with protection kits and protective film, the single-lens reflex camera will add UV protect mirror generally. In addition, users should develop good habits using the camera, we should try to avoid touching the LCD screen with your fingers, not only the lens. SLR camera should also pay attention to reduce the number of disassembly to avoid too much dust to enter.   

Brush with fine material. Most of today's digital manufacturers do not recommend users to conduct dust by themselves. It is reported that manufacturers usually refuse warranty in the damaged parts by the user own demolition, so If it is found that the gradual accumulation of dust in the camera usage, or stains have ingress, we also recommend users have the favorable conditions sent the camera to the experts to resolve.   

Well, for some products have years longer use, or users don't want to spend money on specialized dedusting conservation, how to deal with the dust problem? The technical staff of BenQ digital camera, told reporters that during the lens removal, should pay attention to the following questions :   

Can not use cardboard, paper towel or napkin to wipe the lens, these products are all included the wood pulp could cut or rubbed, would seriously undermine the fragile coating on camera lens . Also do not use benzene and other volatile organic solution to avoid a devastating damage to the lens.   

Right way to safeguard by ourselves is, remove dust particles with a soft brush and blown balloon, and then drop a small drop of lens cleaning fluid in the lens cleaning swab paper ----- carefully not to drop the cleaning fluid droplets on the lens directly, use clean paper swab the lens surface repeatedly, and then use a clean cotton cloth wipe the lens until the lens dry.   

Remember, do not blowing directly on the lens use mouth , because some material in the mouth may be left in the lens caused corrosion.   

The Prevention of LCD's "skin"

Currently a dedicated USB dedusting dryers available in the market, its appearance only a size of a thumb, can plug in the USB port on the computer to operate.   

For some stubborn dust particles, can be removed use electrostatic principle. For example, the pen rod non-metallic, glass, plastic handle or wood smooth objects frict heat in cotton or silk scarf to generate static electricity, then closer to the lens surface with this static objects coule absorb part of the net.   

Photographic equipment stores are currently selling a blowing balloon with a back-end air intake, front-end outlet. If users want to remove dust by themselves, can remove the camera lens, open the clear CMOS function according to the specification, reflective plate will rise and show CMOS, then blow to the CMOS use the inflatable balloon. The gas nozzle can be near more from the CMOS to enhance the effect. Note, this method does not apply for some non-SLR cameras generally .   

Apart from the lens, the digital camera's LCD screen is also very easy to accumulate dust. If stains has found on the surface display, can use some soft cloth with glass cleanerto wipe lightly, they still have to pay attention to the cleaning agents should not be dripping directly on the display surface, if the cleaning agent flows into the sophisticated airframe structure , easily lead to short-circuit and so on.   

Also do not use the hard texture paper or tissue paper to clean the screen, or easily result in scratches left. Digital camera LCD screen surface layer are anti-glare film generally, once membrane of this layer is damaged, it not be able to recover. It is a lot of plastic paper used to affixed on the screen on the market currently, the user can select to purchase and then cut to the appropriate size and pasted on the LCD screen.
