Maintaining the Scanner

Maintaining the Scanner

     Do not touch the glass surface of the scanner. Besides can cause scratches, oil and dirt, it can also damage the surface of the glass, could ultimately affect their prints are less than the maximum. If you want to clean this piece, use a microfiber cloth with a material so that no fiber fabric that remains.
     When the scans an image of a thick book or magazine, you should not use the scanner cover to suppress it. If forced it can can cause the scanner lid hinge is broken or loosened.
     Cleanliness scanner also needs to be maintained. Dirt on the device, usually caused by dust and dirt are tucked in some parts. If ignored, it is not likely due to a buildup of dust can interfere with it, especially if there are scratches
     Wipe with cotton and a little liquid alcohol, then rubbed it gently. Before you get started, we need to ensure the flow of electricity turned off. It would be better if we read the instructions manual prior to clean up and use the scanner properly so that scanner performance remains optimal.

Caring LCD

Caring LCD

     When cleaning the screen, try to always order the device into a power supply cable power off and uprooted. It is necessary to avoid the flow of electricity that may arise, when you was cleaning the monitor screen
     To clean the LCD monitor, it is better if you use a soft cloth and a special cleaning fluid monitor. Avoid liquids that contain alcohol, as pointed out can damage the monitor screen. In fact it is not impossible if the monitor will change color to opaque or exposed to scratches.
     When using cleaning fluid monitor, you should not spray liquid directly on the monitor. To be safe, spray it on a cloth first.
     Perform monitor the cleaning process slowly and do not press hard surface layer monitor. Keep a wiping motion in one direction.
     For the safety of the LCD monitor, use a screen protector to protect the monitor from dust or scratches.
     Should not put speakers or electronic items, as pointed out can cause magnetic interference, thus damaging the display monitor.
     Also avoid the habit of putting monitors or other electronic devices in locations exposed to direct sunlight, as this may damage the electronic resistance

Maintaining the Printer

Maintaining the Printer

     Always use the printer periodically (as often as possible at least 2 times a week), do not let your printer idle for too long, because the ink contained in the nozzle head can clog the drain so that the ink expenses
     Use the facility Clean Head (Software that came with the printer) for cleaning Nozle Head regularly (periodically).
     Clean the printer periodically parts from dust and dirt, do not let any foreign objects into or falls into your printer. Do not use a cloth soaked with water when cleaning the printer
     Do not unplug the printer when the printer is turned off, but use the on / off so that when turned off, the printer head will return to his position so that the ink does not easily dry out
     When printing make sure the paper is not many times but still use paper that is fine, because if caught can damage the printer roller
     Do not touch the electrical parts of the cartridge as the chip and head using your fingers, because static electricity may damage parts of the body sometimes, if forced membersikan use tissue paper with good quality, because poor-quality tissue paper it will leave the paper particles and potentially clog nozle head.
     If using refill ink refill make sure to use good quality, do not fill the cartridge too full because it can lead to leakage of cartrdige and can be spread on the motherboard printer.
     Do not let your empty printer without a cartridge in a long time, because it can cause the print head to dry.
     Note wastepad (waste ink) printer, replace wastepad disposal or use beyond that will not be more likely to smear ink in the printer.
     Never open the printer casing, because the printer components can only be in service by people who really have a grasp of.

Caring for Digital Cameras

Caring for Digital Cameras

     Avoid direct contact with sunlight.
     Keep your digital camera to avoid excessive shock
     Clean the camera and lens.
     Avoid scratches on the lens
     Avoid sea water.
     Do not be too frequent cleaning or cleaning the inside of the lens when the moldy
     Do not store it in the closet
     Beware of mothballs
     We recommend that you remove the battry when the digital camera is not going to use, and keep it away from the fire battry
     Do not ever remove battry or memory card while the camera is still alive, because it would damage the image or the memory card itself
     Insert the memory card correctly, because if one of the camera will hang
     It is important to install your digital camera to your computer first, also format the internal and external memory card when using it the first cal

Caring for Camcorders

     Do tingalkan tape in your camcorder when not in use. Cassettes can cause friction and this can cause problems in the process of recording and playback
     Do not insert a video cassette in really cold conditions. Moisture from the warm air can membut cassette attaches to the drum so that the damage can damage the tape and the video head
     Do not leave the battery in the camera when not in use. Some interesting camera battery energy in small amounts, but the constant so that it can drain the battery
     Do not leave the camcorder tapes in the car exposed to hot air
     Do not put labels on label tape camcorder which is probably against the cassette door opener. This can cause the tape stuck on the camera
     Treat your handycam to give it to the technician to clean the tape head when dirty. Such a treatment could make your camera more durable

Stove research and development

Stove research and development

The search for safer, cleaner stoves remains to many an important if low-profile area of modern technology.^[10] Stoves in common use around the world, particularly in Third World countries, are considered fire hazards and worse: according to the World Health Organization, a million and a half people die each year from indoor smoke inhalation caused by faulty stoves.^[5] An engineer's "Stove Camp" has been hosted annually since 1999 by Aprovecho Research Center^[10] (Oregon, US) with the intent of designing a cheap, efficient, and healthy stove for use around the world.^[11] Other engineering societies (see Envirofit, Colorado, US) and philanthropic groups (see the Gates Foundation, California, US) continue to research and promote improved stove designs.^[10]

Emission regulation

Emission regulation

See also: Air quality law

Many countries legislate to control emissions. In the U.S. since 1992, the Phase II EPA Woodstove Regulations require that all wood stoves being manufactured limit particulate emission to 7.5 grams per hour for stoves with after burners or 4.1 grams per hour for stoves with catalytic converters. ^[9]
The burn temperature in modern stoves can increase to the point where secondary and complete combustion of the fuel takes place. A properly fired masonry heater has little or no particulate pollution in the exhaust and does not contribute to the buildup of creosote in the heater flues or the chimney. Some stoves achieve as little as 1 to 4 grams per hour. This is roughly 90% less smoke than older stoves, and equates to nearly zero visible smoke from the chimney. This is largely achieved through causing the maximum amount of material to combust, which results in a net efficiency of 60 to 70% as contrasted to less than 30% for an open fireplace. (Net efficiency is the amount of heat energy transferred to the room compared to the amount contained in the wood, minus any amount central heating must work to compensate for airflow problems.)
