Scanner with HP's brand is better.
Hewlett-Packard is headquartered in Palo Alto, California, U.S.A. HP has three major business groups: Information Products Group, Printing and Imaging Systems Group, and Enterprise Computer Professional Services Group, and Hewlett-Packard Co., Ltd. is headquartered in Beijing, with branch offices in Shanghai, Guangzhou, Shenyang, Nanjing, Xi'an, Wuhan, Chengdu, Shenzhen and so on.
The scanner is a computer input device, its role is to scan pictures, photographs, films, and manuscripts and other written materials or the appearance of physical objects into the computer, and the formation of documents to save. In fact, the scanner has become the third most important computer input device after the keyboard and mouse.
How to buy a high-speed scanner
1, scanning format
High-speed scanner maximum scanning format is divided into A3 and A4, A3 format high-speed scanner than the A4 format high-speed scanner is much more expensive, so the need for theoretical use of the plea to discontinue the selection, assuming that the demand for scanning the document is basically A4, from the price of thinking, you can choose A4 format on the can, assuming that the need to scan documents A3 format is more, you only need to choose A3 format machine.
2, high-speed scanner scanning speed
Ordinary more than 20 pages per minute to more than 100 pages, but from the price point of view, the scanning speed of every increase in the price of 10 pages of the machine increased a lot, so the need to stop the choice based on the application of the practical requirements to stop the amount of scanning per machine per day to stop the approximate calculations.
3, image enhancement
Buy a high-speed scanner to see if the high-speed scanner in the image enhancement processing can meet the requirements, such as: automatic cutting, deskew, black border, multi-color filtering, color / black and white originals are automatically recognized and other functions. To pay special attention to the attempt to image quality, the same parameter settings in different brands of machines to achieve image quality differences, of course, the image quality is better.
Which brand of scanner is good
Question 1: Which brand of scanner is the best? Canon Canon (world brand, leading brand, the first market share, in 1937 Japan)
MICROTEK in the crystal (domestic scanner flag inkstone brand, the top ten scanner brand)
Thunis Tsinghua Purple light (1988 Beijing, the national key high-tech enterprises, the top ten scanner brand)
Epson Epson ( In 1942 in Nagano, Japan, a global leader in the field of digital imaging)
BenQ BenQ (founded in 1984 in Taiwan, the world's brands, the top ten brands of scanners)
HP Hewlett-Packard HP (1939 California, the world's brands, the top ten brands of scanners)
Hanwang HW (in 1998 in Beijing, the national high-tech enterprises, the top ten brands of scanners)
Hanwang HW (in 1998 Beijing, national key high-tech enterprises, the top ten brands of scanners)
Hanwang HW (in 1988 in Beijing, national key high-tech enterprises, the top ten brands of scanners) scanner brand)
Question 2: What brand of scanner is good? Well-known brands, then preferred Epson, followed by Canon. There are also domestic in the crystal is also a scanner of the old brand, itself is the production of manufacturing optical instruments, so the scanning quality is not lost to the Japanese brand.
Price, in fact, about 300 yuan on it. Because then the high-end are more than a thousand dollars of high-end scanning products. General low-end products, 500 ~ 600 yuan of scanners and 300 yuan or so, in the scanning effect is not much difference. 500 ~ 600 yuan of scanners is just a few more features, and are some of you may not be able to use the life of the chicken ribs function. For example, after scanning a piece of a terrier to send an e-mail or something, this kind of very boring features, and then give you additional unnecessary price.
More importantly, the technology of scanner products has long been thoroughly mature, and there is no great technological difference between different price points and different brands in the same class. So there is no need to spend more money for some external factors. For a scanner, the effect is good is the king, other are floating clouds.
So it's more important to buy one that works well than one that has a lot of features.
In the type of special note, it is best to buy the use of CCD photographic parts of the scanner, CCD scanner is thicker, slightly larger, but must be a good scanning effect, especially the color is more full.
And now on the market are generally recommended that you buy CIS or LED photoreceptor scanner, the only good thing about this scanner is that the volume made smaller, can be made very thin. But the scanning effect is poor.
Question 3: What brand of scanner is better First of all, you have to figure out the most fundamental difference between the two machines EPOSN and Canon low-end:
EPSONV10 is a scanner that uses CCD as the scanning component. The advantage is that you can scan three-dimensional objects, such as the center seam of the book can be scanned very clearly. Then again, the simple point is to leave the scanning platform can also be scanned very clearly.
The disadvantage is that the CCD component is relatively thick, but V10, V100, V200, V350 have improved, become thinner than other brands of CCD, lighter.
Canonlide series with CIS components, the advantages of a shorter warm-up time after powering on, scanning pure black documents faster, but the color effect is not ideal, there is also the difference between CIS and CCD is the opposite of CIS left the scanning platform scanned in the computer's image around the black shadow. Can not be changed.
Scanning resolution is for you to zoom in on the image with little relation to the clarity, scanning text 300dpi, color photos 600dpi is perfectly OK. to scan the color and clarity of the main look at the optical density (which I will not explain here)
All the all-in-one machine with CIS, because of the size of the small, then again is to copy with so the resolution is not high. (There are a few that are CCD but they are expensive). It is the kind of digital enthusiasts like,
Negative scanning do you need to use? Old negatives at home to get out and play? You can~! On the previous SLR camera film does not have to be developed out, but in the scanning into the computer to do PS modification, to achieve the effect they want. (Many are the top photographers use use 120's etc.)
Question 4: Never buy a scanner which brand is good, than the price to buy Canon Canon (the world's leading brand, leading brand, the first market share, in 1937 in Japan)
Chinese crystal MICROTEK (the domestic scanner flag and inkstone brand, the top ten scanner brand)
Singhua Purple Thunis (1988 Beijing, the country's key) High-tech enterprises, the top ten scanner brands)
Epson Epson (in 1942 in Nagano, Japan, the world's leading enterprise in the field of digital imaging)
BenQ BenQ (founded in 1984 in Taiwan, the world's brands, the top ten scanner brands)
Hewlett-Packard HP (1939, California, the United States, the world's brands, the top ten scanner brands)
Han Wang HW (in 1998 in Beijing, the national high-tech enterprises, the top ten scanner brand)
Question five: office scanner which brand of good individuals like to use HP's, the quality is also good, my office printer with three years, in addition to the addition of a mill has never been bad
Question six: which brand of scanner is good now with the high-flying camera, there are scanner All the functions of the scanner, faster than the scanner, the function is also more complete,. Comparison of good brand I recommend Zhelin brand, specifically look on the Zhongguancun Online to see the detailed parameters and introduction
Question 7: I want to buy a scanner, which brand is good now the general scanner are almost the same, the regular manufacturers of things have quality assurance. High-end professional and not the same
Question 8: Which brand of scanner good image quality, of course, is Kodak, image processing capabilities are extremely high quality;
Hardware overall performance, then, recommended small Japanese Fujitsu, stable operating processes;
If you look at the cost-effective, you can also look at the Taiwan and domestic brands, flatbed for home use, then the Epson and Canon are also good.
Question nine: which brand of scanner is good? Currently on the market sales of good brands are mainly in the crystal (Microtek), Hewlett-Packard (HP), Purple (Thunis) and so on. Microtek has been in the world for many years in the scanner boss position, HP focus on high-end products, Purple because of its excellent Chinese character recognition software and favored. 2006 quarterly sales of the highest brand still belongs to the Microtek.
Now, with a resolution of 2400 DPI and a color depth of 48 bits, the Mid-Crystal is just over $300, which is a good value compared to $220 for a non-brand-name scanner.
At $800, you can buy a scanner with negative scanning capabilities.
Brand-name products have advantages in quality assurance and after-sales service. Moreover, there is no risk of counterfeiting because the scanner structure and technology are relatively simple and not very profitable.
So, it is recommended to buy products from Medium Crystal.
Which scanner is better?
With the price reduction of scanners, in computer peripherals, in addition to printers, scanners are gradually entering the office and home, becoming an indispensable computer peripherals. At present, the scanner brand is also quite a lot, but really do a good job of the brand I think it should be Canon Canon, in the crystal MICROTEK, Tsinghua Purple Thunis, Epson Epson, BenQ Benq these good reputation of some of the brand it is on the top ten brand portals to buy buy on the top ten brand of the scanner, buy it or can be assured that Oh.
What brand of scanner is good?

Which type of scanner is more suitable for home use?
Now on the market for small home scanners are a few hundred like to buy cost-effective basic to meet the needs of the words, I bought a flatbed scanner in the crystal.
Currently the best scanner is which
Suggested Tsinghua Purple or Canon, brand name and time are longer, their after-sales are guaranteed, in the Asian business online, you can find
Purple scanner which is good
Scanner market is well known as well as Canon HP Fujitsu Hong Kong Founder are good, the specific need to look at the configuration
High-end scanner which is good?
Hello: do you need A4 format or A3 format scanner? Can you tell me briefly?
What scanner has better scanning elements?
This is what I found out for you, I hope it can help you, I don't know much about it!
All HP scanners currently sold in China use CCD (ChargedCoupledDevice) technology.
Often people mention the scanner, will pay more attention to its scanning resolution, and it may not care about the photoreceptors used. Whether to choose a CCD-type scanner or a CIS-type scanner, many users are confused as to which scanner is more suitable.
Simply put, the difference between these two types of scanners lies in the photoreceptors, CCD-type scanners use electronically coupled devices, while CIS-type scanners use contact image photoreceptors. The working principle of these two photoreceptors are very different: CCD components themselves is the core of the entire scanner imaging, but the light source must be issued by the light reflection and lens focus, the inclusion of these optics to increase the cost of the entire scanner; CIS scanner is the use of a tiny light source issued by the scanner after the reflection of the original by the photoreceptor device to receive direct imaging, the CIS photoreceptor component itself is sufficient to CIS photoreceptor itself is sufficient to complete the imaging task, does not require the participation of lenses and lenses, so the product is very easy to assemble, the cost is lower. Because the CIS scanner relies on the direct reception of reflected light imaging, technology content is relatively low, in the scanning depth of field and other aspects of poor performance. In addition to the difference in the light-sensitive part, the other parts of the two scanners work basically the same way, converting optical signals into digital information.
Contrasting the two scanner products, CCD-type scanners have a clear advantage, but CIS-type scanners are not useless.
CCD-type scanner disadvantages are: the need for a complete set of optical systems, including illumination of the cold light source and a number of reflectors and optical lenses, through a complex optical path in the CCD sensor device surface imaging. Its components are more complex, the cost is relatively high, and the processing of image data after scanning is also relatively complex. Generally use a cold cathode tube as a light source, need to be warmed up about 1 minute to stabilize the light. CCD scanner needs to be imaged through a series of lenses, mirrors, so it will produce color deviation and optical aberration, generally need to be scanned through the software for color correction.
The advantages of CIS-type scanners are: modular design, scanning light source, sensors, amplifiers into one, the structure, principle and optical path are extremely simple. By the sensor directly from the surface of the manuscript to obtain images, theoretically does not produce color deviation and aberration, can obtain the closest image effect of the original. Design and manufacturing costs can be reduced, and the product can be designed to be thinner and smaller in size, with no noticeable wait time for CIS-type scanners.
The disadvantages of CIS-type scanners are: they can't use lenses, they can only scan close to the original, and their scanning accuracy is low. In addition, its light source can only use LED light-emitting diodes, this light source in both the light color as well as uniformity are worse, the color gamut is narrower than the CCD, the color obtained is not as rich as the CCD, and the life of the light source is relatively short.
In addition, the traditional CCD scanner because of the use of optical lens imaging on the surface of the CCD, so it has a certain depth of field, on the spine of the book, and even physical objects can be scanned clearly. CIS scanning head using the sensor to get an image from the surface of the scanned object, the depth of field is shorter, scanning the level of some of the shortfalls in the scanning of the manuscripts and pictures of the unevenly placed appear to be a bit incompetent! CCDs have at least 10 times the depth of field of CIS, which means that CCD scanners are able to scan 3D objects clearly and vividly within a certain range, whereas CIS scanners often produce blurry and out-of-focus images when scanning slightly uneven objects.
High-quality CCD photoreceptors can be guaranteed to last 10,000 hours with no change in quality, while the luminous elements of current CIS scanners lose an average of 30 percent of their brightness after 500 hours of use, meaning that CIS scanners have a shorter lifespan for their luminous elements.
