The testing center of green laser pointer has the powerful researching ability. Do not know idioms colorful, colorful, colorful in the five colors are specifically referred to, for color laser printers, this five colors are cyan, magenta, yellow, black and white. Cyan, magenta, yellow, black is the color of toner, paper white is the background. Cyan, magenta, yellow is the color synthesis "subtraction principle" in the ternary color, plus black and white two colors, can be composed of the entire world of color. The world is the color of the original, just invent a human image reproduction method in the beginning, due to technical reasons, only black and white to reflect the form, such as photography, film and television and laser printing. When the technology develops to a certain stage, is bound to full access to color the world, such as photography, film and television. So if people ask, "We really need to use color laser print?", Then I can not help but ask, "This needs a reason?." The test data sheet of 200mW Laser Pointer ...
... should be renewed.

I believe the vast majority of color laser printing in black and white laser printer with users in mind have a dream, the reason why only the "dream" in the thought of it, or because it's probably the first price. Speaking of color laser printing costs of consumption, where the testing agency quoted a foreign color laser printer for ten kinds of cost of the test results of the most telling. Test conditions are based on 20% coverage for 80 000-color printing, and then calculate the total cost of consumption. Consumption costs include: toner, fuser, toner cartridges, imaging unit of consumption and replacement costs. Supplies minimum fee of $ 5125, the maximum cost of $ 11,136, the average cost of $ 7632, five models of the minimum average cost of $ 5757. The most interesting results is the toner of a price difference from the overall printing costs not directly reflected in the vast majority of the cost of color laser printers print very close to the printing costs of individual models obviously much higher, because The wearing part life is too short, so even though the toner price is low, but the overall consumption costs but much higher. It also reminds us to buy this high-end color laser printer supplies, we must pay attention to their use of consumer cost, not on the "buy the cheap with the expensive" when. The manufacture training of 100mW laser pointer is necessary for the worker.

For about arithmetic, converted into U.S. dollars will be above RMB, we can conclude that, in addition to a printer outside investment, 20% coverage of all the printing cost per page can be not more than 6,7 cents, less than the same effect The one-third of the price of inkjet printing, can print a million copies and inkjet printers total investment will be flat, but after color laser print run cost advantage clearly reflected, of course, high-speed laser printing and on plain paper can be achieved is ink-jet printing can not match. According to network color laser printer designed load capacity, a month to complete the 10,000 or twenty thousand print volume. From this usage can be seen, department color laser printer for network printing use, and in fact more than color laser printers for the network type. In China, someone (presumably sellers) statistics, the color laser printer to print an A4-format color photographs as long as 1 yuan, if the test results according to the above projection abroad, print a 80% coverage of A4 pictures, all the consumable materials cost about more than two money. As a consumer, I prefer the latter as the budget was based, as it is printed 80000 and calculate the cost of all consumption data derived from. The technology review of Blue Laser Pointer is arranged in the next week.

Is such a conservative view some data, but also strong support for the view: color laser printing is absolutely affordable is already a high output, wide application of the obstacles to buy the printer when an input the high cost, so the most appropriate group to use it, and although the average family can afford it but can not afford it. Understand the principles of color laser printer is a more interesting things, which involves permutations and combinations in a classic example, are interested may wish to calculate, see if you can get out of the solution. Color laser printers monochrome laser printer works with the principle of absolute correlation. Black and white laser printer black toner to print. Simple to understand, color laser printer is cyan, magenta, yellow, black four toner to print their own time, relying on color mixing to form a rich color. Understand the principles of black and white laser printer is to understand the basis of color printing, image transformation can be used several times to explain the implementation process. Changing the original bitmap raster image processor, a laser printer will print the page into a bitmap, and then converted to electrical signals sent to the laser scanning unit. The product provided by these two subcontractors of 5mW laser pointer are both good in the quality.

Bitmap variable charge "negative image" in the laser scanning unit, the image on the page point bitmap is converted to a laser signal transmission to the imaging drum, in the bitmap corresponds to each pixel, pixel values are emitted when there is laser beam, not value-free emission. Laser emission produced on the imaging drum when a small light point, imaging drum with a charge in advance, by the laser beam will be discharged to the point, not to the point of exposure is still with the charge, through this process, the page position map was converted into the charge on the imaging drum "negative image." Charge "negative image" to Toner "just as" toner and imaging drum with the same nature on the charge, imaging drum rotation, the charge "negative image" after the developer roller, the discharge point will be charged on the adsorption toner, and the point of discharge is not repulsion is not as same-sex absorb the toner, so that charge "negative image" was turned into a toner "As." The factory inspection and acceptance personnel should sign the report of green laser pointer if green laser pointer is qualified.
