Four hidden defects of inkjet printers that have never been solved

after entering 2010, inkjet printers have entered a climax. New products have emerged one after another, both commercial inkjet printers and household photo printers, and new technologies continue to emerge. In fact, commercial inkjet printers, like photo printers, are words derived from inkjet technology according to different uses and user groups. Photo printer is a printer capable of photo printer. Generally speaking, people like to use ink system to limit the positioning of photo printer. However, as Canon 4-color printer can print enough excellent photos, this definition is gradually blurred. The definition of commercial inkjet printer is broader. Inkjet printers that can be used for commercial purposes are collectively referred to as commercial inkjet printers. Generally speaking, commercial inkjet printers need to have the characteristics of high printing load, high stability, fast printing speed, good text output effect on ordinary paper, etc

compared with household inkjet printers, commercial inkjet printers have higher printing load capacity, faster printing speed, better scalability and larger consumable capacity. Color inkjet printers for business and office mainly print text, and sometimes print some simple graphics and design drawings. Users pay more attention to the speed of the printer and the quality of text printing. Because the commercial inkjet printer adopts the technology of larger memory and multi nozzle ink head, its actual printing speed is generally twice that of the household inkjet printer. Commercial inkjet printing adopts a larger capacity ink cartridge, so the ink capacity is 2 to 3 times that of ordinary ink cartridge. In addition, various color ink cartridges/ink heads can be replaced separately, so the single page printing cost of commercial inkjet printing is naturally much lower than that of household inkjet printing. In addition, commercial inkjet has higher printing load and expansion capacity than domestic inkjet. This means that the reliability of commercial jet printing is higher and the workload that can be borne is greater

the home market is also a market that inkjet printers strive to expand. With the popularization of computers, a single computer application can no longer meet the needs of people's life and work. The modern lifestyle and the promotion of digital images have promoted the demand of home users for printers. Print novels, essays, various documents, design drawings, save pictures, print photos and many other applications. The combination of digital cameras, printers and other peripherals has a wealth of applications that add infinite fun to the life of home users. Some professionals predict that in the next few years, the home user market will surpass the business user market and become the mainstream application field of the printing market

although the position and market share of inkjet printers are getting higher and higher, and although major manufacturers have made technological transformation on inkjet printers in 2010, several major defects of inkjet printers have never been effectively improved

print head plug is the most troublesome problem for inkjet printer users, and many users talk about color change. To a certain extent, the problem of plug has become the biggest enemy hindering the continued popularization of inkjet printers. The reason why the print head plug is difficult to control is that China No. 1 Heavy Machinery Co., Ltd. has started to manufacture 12%cr ultra supercritical rotors in a double vacuum way since 2008. The real reason for the plug is air. After the print head is normally printed and returned, the seal is not tight or it is placed for a long time, and the water is excessively evaporated, resulting in the ink particles drying at the tip of the fine print head, so that the ink cannot be normally ejected; Or different inks are mixed with each other to produce a chemical reaction, which usually shows that there are faults such as broken lines, missing colors, blurred handwriting and even failure to print normally. Classification of inkjet printer plug: it can be roughly divided into soft plug and hard plug

soft plug plugging refers to the broken line fault caused by the increased viscosity of ink on the nozzle due to various reasons. Sometimes it is only attached to the surface of the ink outlet nozzle. It can be recovered by dipping the original ink and cleaning it for many times. The utility model has the advantages of simple and fast operation without any physical damage; The disadvantage is that the use cost is high and ink is wasted. Use the print head cleaning function in the printer driver utility to clean. The utility model has the advantages of simple and fast operation; The disadvantage is that the cleaning effect is not ideal

generally, it is not easy to clean more than 3 times. When the printer plug is not serious, it should be flushed within 3 times. If the plug still cannot be flushed three times, it indicates that the plug is serious. No matter how many times it is cleaned, it may not work, and there is no need to waste a lot of expensive ink. At this time, it should be further treated according to the specific situation. At the same time, there will be air resistance between the ink cartridge (such as sponge filled type) and the print head, resulting in a small amount of irregular disconnection. At this time, it is not necessary to clean repeatedly. Sometimes it can be used normally after being placed for a period of time. Users using inkjet printers should avoid mixing ink. Do not rush to add new ink to the ink cartridge. First, inhale some ink with a clean disposable syringe and carefully observe in a bright place to see if there is any suspended matter in the ink. If there is any suspended matter, do not mix it

canon is the best printer to handle the ink-jet printing plug. Among the ink-jet printers we have used, Canon rarely has plug, especially the mx7600 and ip4680 models, which are not easy to have plug after one year of storage

when the print head is plugged, it is natural to deal with it. At this time, the most common measure is to clean the print head. However, many users will find that cleaning will consume a lot of ink. Sometimes even washing a box of new ink to meet the needs of the automotive industry can not repair the plug, and these ink will be wasted. In addition, many printers will automatically flush the print head before or after work. For example, if the printer is switched on and off frequently, the ink level will drop sharply. Either way, this is due to the principle of the inkjet printer and the structure of the print head. Although after years of technical research and development and innovation, the proportion of blocked print heads has been greatly reduced, the manufacturer still cannot guarantee that the print heads will not be blocked when the inkjet printer is not used for a long time. Therefore, from a technical point of view, the ink consumption in flushing the print head is partly due to product structure and design problems, not due to the user

now, more and more manufacturers will write down such words when promoting their products: adopt the split ink cartridge design, change one color after printing, and effectively save ink. For domestic users who pay attention to cost, ink saving has unlimited appeal. At the beginning of the popularization of the split ink cartridge design from high-end models to low-end models, it has attracted the attention of a large number of users. It is generally believed that the split ink cartridge will be a direction for the development of low-end color inkjet printers. It seems that the split type improved friction consumption ink cartridge design is a great progress. Especially for users of low-end four-color or six color models, the split type ink cartridge design effectively avoids the waste of monochrome ink. However, in many color inkjet printers designed with split type ink cartridges, we replace this ink cartridge after a certain color of ink is polished, After replacement, it will be found that the ink of other colors will also decline to varying degrees

this is because each time the ink cartridge is replaced, the printer will automatically flush the print head and inject ink into the pipeline. Although this process can effectively ensure the consistency of the front and rear inks in the pipeline and avoid the color shift caused by subtle differences between the two inks in particle distribution, such as air heating or lubricant sealing, this process is beyond the control of the user, Washing the print head caused a large amount of waste ink

at present, many printers are provided with chips that do not flush the print head when the printer is turned on, but they still treat the symptoms rather than the root causes. The root cause that can really control ink waste is still the manufacturer

the printer is not a one-time capital investment hardware equipment, so the printing cost naturally becomes one of the factors that must be considered when purchasing the printer. The printing cost mainly includes ink cartridge and printing paper, so the type of ink cartridge should be considered when purchasing. If the printer uses black ink to print black, it can save relatively expensive color ink cartridges, which is conducive to saving printing costs; The low-grade single cartridge inkjet printer is not equipped with black ink, and the black printing is through color synthesis. In addition, most printers have a good effect of printing black-and-white text on ordinary paper, but to print colorful images, especially the exquisite printing of pictures, it needs to be carried out on professional paper, which means that the printing cost is increased

for a long time, the ink of inkjet printers has been known as the most expensive liquid in the world, and its printing cost is staggering, which causes a large number of printer users to abandon them soon after purchase because they can't afford the later investment. This situation has been alleviated on some HP inkjet printers, such as k109a. In fact, HP k109a has no technical content in reducing the cost of single page printing. There are two ways: one is to increase the ink capacity in the ink cartridge, and the other is to significantly reduce the price of the ink cartridge. Due to the limitation of HP inkjet printer using thermal foaming printing technology, two-thirds of the internal volume of its ink cartridge is occupied by sponges. There will be great resistance by increasing the ink capacity. At this time, price reduction is the best way

when the HP D730 and f735 were just released, we also conducted a cost test on them. However, at that time, the selling price of the ink cartridge was ¥ 88, so the single page cost data of ¥ 0.11 was obtained. Now, the price of a single ink cartridge of the 703 ink cartridge group used in k109a (also the ink cartridge used in D730 and f735) has dropped to ¥ 79 in a famous mall in China, and in the retail market, it can be bought at ¥ 70, which reduces the cost of single page printing. In the future, as long as HP is willing, it can reduce the printing cost to any horizontal line

however, these low-cost products are still concentrated in some individual models, which also leads to the lack of popularity of low-cost machines. Users still take a wait-and-see attitude towards this. The prosperous compatible ink cartridges and continuous supply in the market provide users with a new way to save money

as far as the printing equipment itself is concerned, the two most important properties are speed and quality. These two factors constitute the comprehensive performance of the printer. Like the horizontal and vertical coordinates, they mark the location of a product in the field of printing equipment. If the print quality belongs to subjective impression, and everyone has different standards, the print speed is an objective number, and the number is very precise, and will not change with the user. The printing speed test will be affected by the environment and the paper, and will cause small differences in the final calculation results, which is inevitable and acceptable to the user. In the actual test, the printing speed is often different from the nominal value. For example, the nominal 20ppm printer may only barely reach 8ppm in our test results

this is because: 1. The manufacturer's nominal value generally does not disclose the printing environment, which is the highest speed that the printer can achieve under the best operating environment. We
