Timely Treasure

The computer, like any electronic device that can operate without any user intervention or specialist. And really, nobody did not occur to carry out maintenance TV or tape recorder. However, the computer has one peculiarity – it is high heat components of a system unit. And considering that all the components together in one enclosed space – the system unit, the absence of efficient cooling can lead to overheating and fire the system unit. Therefore, the cooling system components of the system unit is the "Achilles heel" of today's computers. Let us consider, from which cooling system is a computer. In most cases, a set of radiators and fans.

The radiator removes heat from the electronic component and having a large area of contact with the surrounding air by a large number of thin edges, giving the allotted warm the surrounding air, having a generally lower temperature. Fans need to improve air circulation around the radiator, as in a closed system block natural air circulation is absent, and the hot radiator air does not go away naturally. The list of components of a system unit, requiring compulsory teplootvedeniya enough large: 1. Processor 2. North and south bridge mainboard 3. The graphic chip card 4. Power supply in each of these components is the radiator, and some more and the fan.

And the entire cooling system is working the system unit regularly as long as the inside of the dust does not appear. Dust – is the worst enemy of your computer. The dust settles on the edges of the radiator and prevents heat transfer between the heatsink and surrounding air. Dust clogs the space between the ribs radiator and prevents the passage of air. She settles on the blades of the fans, which leads to disruption of balancing the impeller and, consequently, an increased level of fan noise and the rapid breakdown of his bearings. All this leads to a deterioration teplootvedeniya and eventually to the common "freeze" the computer, spontaneous blackouts and can even cause a fire. How to deal with dust in the computer system unit? First and foremost – is prevention. Computer system unit must be kept in a clean, well-ventilated place. Regularly every three or four months to open the side cover and the system unit to conduct surface clean with a vacuum cleaner with a plastic nozzle. But if prevention does not help the whole system unit clogged with dust, it is necessary to carry out a complete cleaning of the system unit. This procedure is best left to specialist. But if you are confident in their abilities, then step by step instructions for a complete cleaning system unit from dust with photos is available on our website.

Laser printers are gradually becoming more common. And the quality is not the only factor by which this occurs – an old printer with a fresh needle tape also gives very clear and image with lots of juicy details. For this reason, when choosing a printer should focus more on the desired speed, the possibility of using the fonts and graphics, usability and comfort of work, of course, the price and operating costs, too. Each type of printer has its own characteristics concerning the types of paper used, interfaces, management, etc. But the quality and speed still remain main factors. Under consideration is the most famous printers printer HewlettPackard.

It so happens that this company is now selling a number of printers that none of the strengths in this area firms such as Epson, LaserMaster, QMS, Texas Instruments, Printware, Data Products or Star, can not even come close to it. Apparently, one of the reasons is that HP made the first commercial laser printer in 1984. Perhaps the popularity of HP printers has led to many competing firms producing printers looks very similar to products Hewlett-Packard, and even refill cartridge hp is not expensive. But this does not mean that they are 'stripped' – far from it. Just the heart of all these devices is a printing mechanism (in English engine, usually in Russian drive) of Canon ink cartridge refill canon will cost a bit more expensive. It defines the layout of the printer, its size, speed and resolution, type of supplies used, the maximum field of printing.
