The majority of this fault is due to the printer has not been used for a long time or other reasons, resulting in an obstacle to the ink delivery system or nozzle clogging. The method of elimination is to perform a cleaning operation.
2, replace the new cartridge, the printer on the panel when the "ink" light on the treatment
Normal circumstances, when the ink has run out of "ink" light will be on. Replacement of new cartridges, the printer panel on the "ink" light is still on, this failure, one is likely to cartridges are not loaded, another possibility is to take down the old cartridges in the shutdown state on their own, replace the new cartridge. Because after replacing the cartridge, the printer will be inked to the ink delivery system, and this process will not be carried out in the shutdown state, so that the printer can not detect the reinstalled cartridge.
In addition, some printers measure ink capacity using the printer's internal electronic counter to count (especially on the color ink usage statistics), when the counter reaches a certain value, the printer to determine the ink exhausted. And during the cartridge replacement process, the printer will reset its internal electronic counter, thus confirming that a new cartridge is installed.
Solution: Turn on the power and move the print head to the cartridge replacement position. After the cartridge is installed, the printer is allowed to charge the ink, and the fault is eliminated at the end of the charging process.
3, the printhead soft plug processing
Soft plug plugging refers to a variety of reasons caused by the viscosity of the ink on the printhead due to the fault of the broken line. General use of the original ink cartridge can be restored after a number of cleaning, but this method is too wasteful of ink. The simplest way is to use the empty cartridges in your hands to carry out the cleaning of the printhead. Before cleaning with an empty cartridge, first use a syringe to draw out as much residual ink as possible from the cartridge, the cleaner the better, and then add the Smart River 961 cleaning fluid.
961 cleaning fluid is specially developed for EPSON, divided into liquid A, liquid B. Liquid A cleaning power is stronger, used in the treatment of medium plug, but can not stay in the nozzle for a long time. liquid B cleaning ability is weaker, but the use of a higher safety factor, the liquid can be 2 (liquid B): 1 (EPSON red or blue ink) to blend, blended with a half-color ink to use in the EPSON Photo cartridge half-color ink. Half-color ink for EPSON Photo cartridges. Refill the cleaning fluid, should be in a clean environment, will add a good cleaning fluid cartridge according to the printer's normal operation on the machine, and constantly press the printer's cleaning key to clean it. Use the residual ink in the cartridge and cleaning fluid mixed with the light color of the print test, normal after the replacement of good cartridges can be used.
4, the printhead hard plug processing
Hard plug refers to the printhead within the chemical solidification or impurities caused by the plug, this troubleshooting is more difficult to deal with, must be handled manually. First of all, the nozzle should be unloaded, the nozzle immersed in the A liquid with backwash pressure to clean. Wash through the clean liquid with pure water, after drying can be installed. As long as the hard objects do not cause damage to the nozzle electrode, after cleaning the nozzle is still good.
5, the printer cleaning pump nozzle troubleshooting
Printer cleaning pump nozzle problems are more, but also cause one of the main factors of the plug. Printer cleaning pump nozzle on the printer nozzle protection plays a decisive role. After the printhead trolley back to position, to be cleaned by the pump nozzle of the printhead for the weak pumping process, the printhead for sealing protection. In the printer to install new cartridges or nozzles have broken lines, the lower end of the machine suction pump to pump through it on the nozzle, the higher the precision of the work of this mouth the better. However, in actual use, its performance and airtightness will be due to the prolongation of time, dust and ink in this mouth of the residual solidification of the increase and reduce. If the user does not check or clean it often, it will make your printer nozzle constantly out of some failure.
Maintenance of this part of the method: the printer's top cover removed to remove the trolley, with a syringe inhalation of pure water to rinse, especially to the mouth of the inlaid microporous gaskets fully cleaned. Here to remind users in particular, cleaning this part, never use ethanol or methanol to clean it, which will cause this component inlaid in the microporous gasket dissolution deformation. Another thing to mention is that inkjet printers should try to stay away from high temperatures and dusty working environment, only a good working environment to ensure that the machine long normal use.
6, the detection of the ink line normal and printing accuracy significantly worse processing
Inkjet printers in the use of the number of times and the extension of time and printing accuracy gradually deteriorate. Inkjet printer printheads also have a life expectancy. Generally a new printhead from the beginning of use to the end of life, if nothing goes wrong more smoothly, that is, 20-40 cartridges of the amount of life. If your printer has been used for a long time, and now the printing accuracy deteriorates, you can use the replacement of ink cartridges to try, if you change a few ink cartridges, the output of its print results are the same, then you will have to replace the printer's printhead. If there is a change after replacing the cartridges, it means that you may be using poorer quality non-original ink in the cartridges.
If the printer is new, the results of the print can not satisfy you, often appear in the print line is not clear, text graphics skewed, text graphics fuzzy outer boundaries, print ink control synchronization accuracy is poor, which means you may buy a fake ink cartridge or use of ink cartridges are non-original products, should be replaced immediately.
7, walking trolley misplaced head treatment
EPSON inkjet printer walking trolley track is made of two powder alloy copper bushings and a round steel axis of the precision combination of sliding to complete. Although the walking trolley is designed to install a piece of oil-containing felt pads to supplement the shaft lubricant, but because we live in an environment where there is dust everywhere, over time, will be due to air oxidation, dust damage to the surface of the shaft lubricant aging and failure, then if you continue to use the printer, it will be due to the friction between the shaft and the copper bushings to increase the friction caused by the trolley walking in the wrong place until the collision of the car head caused by the inability to use.
The solution is: once this failure should immediately turn off the printer power, the hand will not be back to the trolley pushed back to the parking space. Find a small piece of sponge or felt, put it in the sewing machine oil to soak up the oil, and hold it with tweezers to rub it back and forth on the spindle. It's best to remove the spindle, wash it and oil it.
Another kind of trolley bump is caused by damage to the device. Printer trolley parking space above a photoelectric sensor, it is to provide the printer board to print the trolley reset signal important components. This component if the dust is too large or damaged, the printer's car will be unable to find the return signal touched the head, resulting in the inability to use, generally out of this fault when the need to replace the device.
8, disconnection fault handling
Printing disconnection is a common problem, generally caused by the following reasons:
1) new cartridges on the machine, basically only once or twice to clean the print ink line can be normal, and generally do not break the line in use. The reason why the line is often broken is that the user does not set the paper feed tray before printing, the paper feed process caused by rolling paper, paper and nozzle friction caused by the broken line.
Solution: Set the paper feed tray.
The other type is the original ink is running out, not in time to replace the new cartridge, but the printer is placed in a higher temperature environment for a longer period of time. General a cartridge installed after three months to be used up immediately after the replacement, if the replacement of the cartridge is not often used, will be due to the role of the air into the cartridge leading to airtight performance deterioration, easy to make the ink in the nozzle, the viscosity of the cartridge, resulting in the inkjet printer line breaks the fault.
Solution: replace the cartridge, clean the printhead.
2) Replacement of other brands of cartridges common problems
Replacement of other brands of cartridges produced by the line because the physical and chemical properties of the cartridges do not meet the parameters required by EPSON cartridges. We are replacing other brands of cartridges, can sometimes be found, some colors out of the ink smoothly and some colors to be cleaned after a number of times to come out, a large amount of ink waste. This is because the cartridges produced by these manufacturers are far less than the technical requirements of the EPSON cartridges, the use of ink is most likely to occur when the problem of unbalanced ink delivery.
The original cartridges in the chemical characteristics of the ink and cartridge air pressure regulation on the article, while some other brands of cartridges do not understand the principle of the cartridges made by the gap is large, it is difficult to reach the balance of the ink flow. More seriously, some of the cartridges due to the sponge more dissolved matter, sponge ink expansion coefficient is too large, the use of stainless steel ink outlet ultra-fine filter can not meet the requirements of this cartridge to the printer failure is reasonable.
3) to the ink cartridge to add ink problems
The use of ink cartridges after injection of common failures are: line breaks, plugging, chromaticity is not allowed.
If you inject the ink, physical and chemical properties and the original cartridge residual ink is basically similar, it is completely usable. Because we manually add ink in the air at atmospheric pressure to complete the amount of ink injection of various colors is not possible to grasp the very same, add the ink molecules will have more bubble content, then you will be mounted on the cartridge after the machine do not rush to use immediately, but to clean the nozzle one or two times after the printer will be turned off. To shut down for about 2-6 hours and then use it again, then the ink inside the cartridge will be due to the role of the chemical automatic exhaust, has been the bubbles and air to the top of the cartridge, which you can then use to reduce the failure.
