Introduction from the analysis of continuous supply failure, the application and development of inkjet printing

continuous ink supply has always been a hot topic because of cost and money saving. However, continuous ink supply has always been a hot topic, not only because of the topic of saving money and cost, but also because of its stability of failure rate, which also keeps it high in the hot list. If you just talk about the crime and punishment of continuous confession, you may not be able to clearly understand the advantages and disadvantages of continuous ink supply, but from the perspective of use to analyze the cause of the failure, you can fully understand the continuous confession, and also know where the future application and development of inkjet printing should go. Next, let's start with the use failure cases of continuous supply

case 1: unable to recognize the ink cartridge

users who use continuous ink supply may often encounter such a situation: the machine is not printing after being used for a period of time, because the printer cannot recognize the black ink cartridge

fault cause and solution: this situation mainly occurs because the waste ink bin of the printer is full. In fact, every inkjet printer has a fixed accessory life setting. When some accessories reach the service life, the printer will prompt that they cannot be printed. Because waste ink is easy to form during the use of the continuous ink supply system, it is easy to cause the waste ink bin to be full. There are two ways to deal with this situation: or use the reset software to reset the printer motherboard, so as to eliminate the setting of the printer; Or you can go to the maintenance point to replace the sponge in the waste ink bin. The author suggests that users adopt the latter. Because it is easy to cause waste ink to miss and burn the printer simply by clearing

case 2: the swing speed of the print head car slows down, resulting in low-speed printing

the transformation of the continuous ink supply system will often transform the original ink cartridge, which will inevitably cause the burden of the word car. When the load is too heavy, the cart will move slowly. Moreover, the overload will also lead to the accelerated aging of the printer belt, which will be quickly converted from a/d to digital signals and sent to the computer to stop data processing and increase the friction between the word cart and the connecting rod. These will cause the printing speed to slow down. In serious cases, it will also cause the word cart to be unable to reset and then cannot be used

fault causes and solutions: 1. Replace the motor. The rubber hose of the continuous ink supply system rubs against the wall of the printer, causing the load of the electric motor to increase, and the electric motor is lost after long-term use, so try to replace it

2, lubricate the connecting rod. It has been used for a long time, and the friction between the carriage and the connecting rod in the machine increases, which leads to the slow operation of the electric motor. At this time, lubricating the connecting rod can solve the problem

3, the printer belt is aging. The friction of the driving gear connected to the motor increases and accelerates the aging of the printer's belt. At this time, cleaning and lubrication can reduce the aging failure of the belt

case 3: the printer nozzle is blocked

this is one of the most common faults after the printer is installed with the continuous ink supply system. Due to the heavy impurities in the ink, it is easy to cause sedimentation, so the printer nozzle will be blocked

fault causes and solutions: the blockage of the nozzle is almost caused by the precipitation of impurities, and part of it is due to the corrosion of the nozzle caused by the strong acidity of the ink. If the ink delivery system is blocked or the print head is blocked because the printer has not been used for a long time or non original ink is added, it is best to clean the nozzle. If washing with water can't solve the problem, you can only take down the nozzle, soak it in pure water at about ℃, clean it with ultrasonic cleaning machine, and dry it after cleaning. If repeated cleaning still has no obvious effect, it means that the nozzle orifice has been blocked, and this destructive failure can only replace the nozzle

in addition, it should be noted that the service life of printer nozzles is limited. For example, the service life of Epson's inkjet printer nozzles is about using ink cartridges. Therefore, continuous ink supply is not always used to ensure low cost

in addition, the failure of the cleaning pump nozzle of the inkjet printer is also the main cause of the plug. The printer cleaning pump nozzle plays a decisive role in the protection of the printer nozzle. After the carriage is returned, the nozzle shall be weakly pumped by the cleaning pump nozzle, and the nozzle shall be sealed and protected. When a new ink cartridge is installed in the printer or the nozzle is disconnected, the suction pump at the lower end of the machine should pump air through it to the nozzle. The higher the working accuracy of the suction pump, the better. However, in actual operation, the performance and air tightness of the suction pump will be reduced due to the extension of time and the increase of dust and residual solidification of ink in the mouth. If the user does not check or clean it frequently, it will make the printer nozzle continue to appear similar to the plug failure. Therefore, the suction pump should be maintained frequently. The specific method is to remove the upper cover of the printer, remove the car, and wash it with pure water inhaled by a needle tube, especially fully clean the microporous gasket embedded in the mouth. It should be noted that when cleaning this component, it must not be cleaned with ethanol or methanol, which will cause the dissolution and deformation of the microporous gasket embedded in this component. At the same time, do not touch the lubricating oil to the pump nozzle. The grease will deform the rubber seal ring at the pump nozzle and cannot seal and protect the nozzle

case 4: after replacing the new ink cartridge, the panel displays ink exhaustion

generally, the ink exhaustion light on the control panel will be on only when the normal ink consumption is late. If the ink out light on the printer panel is still on after replacing the new ink cartridge, the printer has failed

fault causes and solutions: one of these faults may be that the ink cartridge is not installed properly or there is a problem with the ink cartridge itself and the detection circuit. Another possibility is to remove the old ink cartridge and replace it when it is turned off. The China building waterproofing Association announced a research report at the 2014 annual meeting of the building waterproofing industry that the new ink cartridge should be installed. After replacing the ink cartridge, the printer will fill the ink delivery system with ink, and this process will not be able to be carried out in the shutdown state, so that the printer cannot detect the reinstalled ink cartridge. At the same time, some printers use the electronic counter inside the printer to count the ink volume, especially in the statistics of color ink usage. When the counter reaches a certain value, the printer judges that the ink is exhausted

during the process of turning on the printer to replace the ink cartridge, the printer will reset the internal electronic counter, confirm that a new ink cartridge is installed and start to recognize. When the ink cartridge is replaced with a new one when it is turned off, the counter in the printer fails to reset, so it still reports ink exhaustion

fault cause and solution: reinstall the ink cartridge when the machine is turned on. However, if the fault persists, you must try to replace it with a normal cartridge to verify whether it is the cartridge problem or the detection circuit problem. If there is a problem with the detection circuit, it means that the electrical contact on the cartridge rack where the cartridge is installed is contaminated or corroded by ink, resulting in poor contact with the cartridge, so the cartridge cannot be detected. The solution is to clean the contacts with alcohol or replace the cartridge rack

case 5: the printer cannot print after inking

the continuous ink supply system will often add ink to the container, and sometimes the printer cannot print normally after adding ink

fault causes and solutions: this fault is mostly due to the excessive filling times of ink, which brings a serious burden to the printer, and finally leads to the inability to print. There are many reasons for the failure of printing, such as the waste ink pad is full, the printing nozzle is blocked, or there is a problem with the movement of the word cart. In this regard, users should often maintain the printer to avoid the continuous occurrence of faults

after analyzing five practical cases of continuous ink supply, some users may ask: is continuous ink supply stable? Does continuous ink supply often fail? The author's answer is yes

thinking about the stability of continuous ink supply

during the use of continuous ink supply, printer failures are often caused by ink, structure or modification. Although the causes of failures are different, one thing is certain: the use of continuous ink supply system accelerates the physical damage of the printer

from the actual fault analysis, we can see that using continuous ink supply is easy to cause accelerated aging of printer components and nozzles. Moreover, the modified structure is also easy to cause abnormal movement of the word car. These failures all indicate that after the continuous ink supply is installed, the service life of important components of the printer is shortened due to structural changes

using a continuous ink supply system cannot be guaranteed. Because users do not use it under abnormal circumstances, it also increases the economic burden of users in the maintenance process. In addition, the use of continuous ink supply system often leads to the scrapping of printer waste ink pad and the burning of printer components due to the waste ink problem. It is believed that replacing waste ink pads and components can also cost a lot of money, which is an inevitable result

here's a user's actual experience: a user modified the continuous ink supply system after purchasing an Epson inkjet printer. When printing less than 3000 photos, the printer has been reset, the paper wheel has been repaired, the sensor has been changed, and the wiring has been repaired. Due to abnormal use, it costs more than 700 yuan. C. capacity segmentation: Auto rang. And the maintenance time also took more than a month

the occurrence of these failures, in addition to the waste ink counting chip counting limit caused by the waste ink problem of the inkjet printer, it also shows that after the continuous ink supply system is installed, some parts of the printer (such as the paper take-up wheel replaced by the user, etc.) have undergone rapid aging, resulting in frequent printer failures. In addition, the use of continuous ink supply system is also easy to cause sensor failure. For example, the waste ink pollution sensor leads to poor paper feeding, which is also a common problem when using the continuous ink supply system. There is also the use of a continuous ink supply line, which is also prone to aging after long-term use. These are important hidden dangers that cannot be ignored in practical use

some people may ask why there are so many problems in the serial confession that people are flocking to it? Because of the cost, because of the need for continuous printing. However, it is gratifying that Epson's L series products have solved the user's needs on the basis of these two needs, which will make the valve and oil circuit jam. In terms of technical principle, the L-Series original ink bin printer is a more stable continuous printing ink-jet printer, and the cost is as low as 0.007 yuan. Therefore, in the future, ink-jet printing is likely to develop towards desktop level stable output and continuous output, and pay more attention to the late cost and the low purchase cost of consumables
