This time, we followed the last description, talk about how to solve the situation when the ink system meet problems.
Six, Solution for the
ink system
(A) bubble failure
Fault phenomenon
◇ continuous ink system has been working for a few months, and now can not print.
◇ every day in the normal print before the implementation of many times to clean the order.
◇ print the test line is always a fixed disconnection.
◇ just start the test line is normal, but after printing a few pages appeared disconnected.
◇ print is always missing (usually black)
◇ external ink cartridges on the low has been a long time, and now ink pipeline is not into the ink.
Solution
The above phenomenon is due to the ink bubbles in the cartridge caused by the bubble. Continuous use of the ink supply system After six months of use, a small amount of tiny air bubbles from the ink and the accumulation of a small amount of air bubbles from the printhead into the print cartridges gradually expand the ink. Maintenance methods are not complicated, take out these bubbles for the normal ink can be. Incorrectly lowering the external ink cartridge will also accelerate the formation of the ink bubble, even if a continuous ink supply system using EPSON original ink cartridges is used.
To troubleshoot this problem, follow these steps:
1, the continuous ink system from the printer to remove, after removal, the print cartridge should not be inverted, to be placed on the same level with the external ink cartridges. If a seal plug is used at the initial installation, insert the seal plug into each outlet of the bottom of the cartridge. For EPSON late production of the cartridge with a memory chip models, because the ink port with a valve, so no need to seal the plug. Install a new or used EPSON original ink cartridge on the printer. This cartridge must be an unpacked, unpacked, undamaged original ink cartridge. The genuine original EPSON cartridge can guarantee the correct test result , This step is essential.
2, print the ink car after homing, the printer will perform a natural cleaning time, please perform the nozzle check print test line. You can repeat the cleaning and printing test line 3 times, until the test line is completely normal. And then print a four-color or six-color block test chart (depending on your model, print settings in 360DPI
/
Plain paper mode), color test chart must be printed continuously 3 to 5, while observing the printer is working properly. If the print has an exception, repeat the above steps. If you do not have more than 3 times after cleaning, the printer is still not normal, allowing the printer to rest for 12 hours and then test. In most cases the printer can return to normal.
When the printer prints the color chart is stable, it is ok that your printer nozzle is intact. Once you have reached your printer's normal conclusion, you can continue with the following steps to maintain your continuous ink supply system.
If you still can not print properly after using the above method, please contact the EPSON service center or contact the printer repair shop for repair. Although at this time non-continuous ink system failure, contact with us can still get the appropriate help. Before deciding whether to repair the EPSON service center, please remove the parts and labels of the continuous ink supply system and do not refer to EPSON using a third party ink or continuous ink supply system, only that you are using EPSON original ink cartridges and Explain the phenomenon of failure can be.
3, when your printer is working properly, the following steps can make your continuous ink supply system back to normal.
Add 50 ml of disposable syringe tube (remove the needle) with a small elbow and insert it into the ink outlet at the bottom of the print cartridge connected to the continuous ink supply system and begin to dip out of the cartridge slowly. Should be through the ink through the pipeline from the external ink cartridge inhaled into the print cartridge, and then by a steady stream of inhalation into the syringe tube. When the syringe tube is full, observe how much ink and foam will be drawn to see what causes the continuous ink supply system to print poorly. The printer does not print the bubble-like ink normally, and you must pull them out through the syringe.
Unlock the ink cartridge from the external cartridge and inject the ink from the syringe into the external cartridge. This process does not waste ink, and the foamy ink turns into liquid ink after two hours.
This ink extraction process is repeated with a syringe until almost no foam is seen in the extracted ink. This takes about 100 ml of ink to be recycled. That is, it is necessary to repeat the two ink extraction process.
Note: the ink extraction process to be slow, you can pause, do not be too fast.
According to the yellow → light red → magenta → light blue → cyan → black order to carry out the above ink extraction process, color change operation, be sure to use warm water to clean the syringe. If your cartridge uses a sealing plug, the other ink outlets are sealed with a sealing plug when operating on a color chamber.
4, the ink cartridges together with the continuous ink supply system back to the printer, according to the operation of the second step to test debugging until normal.
(B) pipeline blockage failure
Fault phenomenon
◇ Many times the implementation of the ink extraction process, the syringe pumping force needs a lot, and the majority of the air out.
◇ have a completely disconnected (usually black)
Solution
According to the "bubble generation in the cartridge" troubleshooting program, if it is found that there is a great resistance when drawing with a syringe, and no ink flows into the syringe, it can be concluded that the pipe is clogged, Pipe clogging phenomenon and its handling methods, please check and troubleshooting in order.
◇ out of ink mouth blockage.
Check the method: the external box above the seal plug, inverted. From the external cartridge out of the ink tube, check the Yao is blocked.
Exclusion method: with the syringe needle into the ink mouth, you can clear.
◇ ink clogged clogged.
Check the method: the ink out of the elbow from the cartridge, and then pull out the ink from the ink line elbow, check whether the blockage.
Exclusion method: clean the elbow with water, blowing with your mouth, you can clear.
◇ ink pipeline blocked.
Check the method: to ensure that the ink out of the mouth and the ink elbow are not blocked, with a syringe from the ink cartridges ink, if the ink inside the ink cartridge does not float, can be inferred that the ink pipeline blockage.
Remedy: first check whether the ink at both ends of the pipeline caused by foreign body blockage. If there is a short crystal or foreign body, you can use straightened paper clips to remove it; if it is blocked through the long pipeline parts, please contact the local dealer to buy a new six rows of pipelines (four rows of pipelines).
◇ The air filter of the external cartridge is blocked.
Inspection method: In the above three may have been excluded circumstances, can be judged as an external cartridge air filter plug.
Remedy: Clean the air filter, dry water, you can. [6]
(C) the chip is damaged
Fault phenomenon
◇ ink on the printer instructions red light is always bright, shut down and then open is also invalid.
The decoder is not valid after decoding the cartridge.
◇ The printer does not perform cleaning after pressing the cleaning key.
◇ When the print job is canceled, the ink on the printer indicates that the red light is on.
When the computer is restarted, the ink on the printer indicates a red light. [7]
Solution
1, EPSON models. The disadvantage is that the cartridge is removed and then returned, the print will be broken, you need to have a repeated cleaning and testing process.
2, if it is a cartridge with a chip model of the above phenomenon, please carefully check whether the following possible:
The ink cartridge is not installed in place.
The chip position on the cartridge is not correct.
◇ chip on the chip stylus deformation.
◇ chip damage.
The first two cases through the operation can be troubleshooting, as long as the adjustment of the location of the chip, the cartridge gland pressure on the ink cart on it. The third case can be found by observation, this failure is because there is no fixed chip installed and forced to remove the cartridge caused by! The But because of the repair will have to have the experience of maintenance personnel will be removed from the printer nozzle, and then remove the needle to correct or replacement. For the case of chip damage, the use of the decoder on the original cartridge chip memory refresh mode, it will often appear, then you can use another decoder to re-refresh once, if it is not normal, can only replace the chip. Continuous ink supply system is equipped with a real permanent ink cartridge chip, because the installation of continuous ink supply system does not need to remove the cartridge to decode, the possibility of chip damage is very small. At present, the regular manufacturers of the system for the production of the chip are very high quality, but the installation of the same time there will not recognize the machine, the solution can use the skin, is the student with the rubber, repeatedly wipe the chip position. The re-installation is basically a recognition of the cartridge.
3, the method of decoding the chip to refresh In addition to hardware, software technology has developed rapidly, but some software in the use of abnormal problems or damage to the printer caused by the depth, so before use must have a senior technical staff Do the guidance, do not do not try to grasp, because the various software usage varies, limited space here is no longer one by one introduced. Should keep in touch with us in order to get the latest software technical support.
(4) ink gravity phenomenon
Fault phenomenon
◇ When printing, there is a small ink dot on paper.
◇ print on the paper often appear when the large leakage of ink spots.
◇ Regardless of what paper to print, there are always some ink on the edge of the ink.
◇ The printer feed roller always has some ink stains.
◇ print the test line is always broken, and the phenomenon of color string.
Solution
A siphon breakpoint is designed in a continuous ink supply system. If there is no such design, the ink will flow along the ink from the external ink cartridges automatically flow to the printer, resulting in leakage, broken wire failure. Our filling technology for empty cartridges allows the filling of empty cartridges to have a small portion of the air space, so that these air is suspended at the top of the cartridge is very necessary.
The following conditions can cause ink gravity to cause printing to be abnormal:
First, the external ink cartridges raised, the liquid level than the print nozzle horizontal 50 mm, due to ink flow within the ink gravity caused by gravity, then the ink will flow out from the print nozzle, lift the higher the faster flow. At this point the print head to withstand the exceptionally large ink pressure, printing will appear leakage, broken, the color of the string and other very serious situation.
Second, the print cartridge is too much ink, because there is no siphon breakpoint, ink pipeline and print cartridge as a whole, even if the external cartridge is not raised, will lead to slow flow of ink. At this point there will be printed ink leakage, broken the phenomenon.
Third, the external ink cartridges raised, the liquid level than the printing nozzle horizontal 30 ~ 50 mm, this time the ink will not flow, but the nozzle is also subject to the static pressure of the ink, so the same print will be broken, the phenomenon of color string The
Fourth, the external ink cartridge is lowered, the liquid level is lower than the horizontal level of the print nozzle 300 mm. As the ink gravity in the ink supply line causes the reflow of the external ink cartridge, the air enters the print cartridge from the print head, The lower the air, the faster. At this point the print will be out
Is broken, the color of the string and other very serious situation.
If any of the above problems occur with your printer, check that the fault is caused by an elevated or lowered external cartridge. (Warning: continuous ink supply system in use requires external ink cartridges must be placed in the same level on the printer !!!)
Eliminate the above first, three, four cases caused by the failure of the method is very simple: the external ink cartridges placed in the same level with the printer, wait 2 hours after the print on the natural normal. And for the second case caused by the failure, the following steps can be ruled out:
◇ put the ink elbow from the print cartridge on the set, on the high, pay attention, do not let go, the ink will flow out from the elbow.
◇ Let the printer start working, playing the picture A4
5-10 sheets, and then the elbow can be inserted into the printer cartridge, be careful not to insert the wrong color. If necessary, perform the cleaning and printing test program in the application and debug the printer properly.
If there is a lot of ink stains in the paper path, you can find a color spray paper, wet the paper with alcohol, and then press the paper feed button on the printer, so that the alcohol soaked in alcohol 10 times, can play a very good cleaning effect.
(5) ink cartridges leak
Fault phenomenon
◇ normal use, an ink pipeline appeared throughout the air.
◇ normal use, each of the ink pipeline are filled with air.
Solution
As mentioned earlier, the continuous ink supply system connected to the upper part of the print cartridge has a short section of air is always present, this is to avoid the siphon principle caused by ink gravity phenomenon. If you see some small air bubbles in the ink line, do not worry, they will be printed on the upper part of the ink layer to absorb the absorption, which is normal.
The air layer in the upper part of the cartridge will expand or contract with the change of the indoor temperature. If the ink is not more than 150 mm in the ink supply line at the interface with the print cartridge, this is due to the air layer Expansion caused by, is a normal phenomenon. However, if the entire ink line appears air, this is the ink cartridge leak or refueling elbow interface is not caused by the seal.
If there is an air in the entire section of the ink supply line, check the seal at the ink filler and the print cartridge. You can remove the ink elbow to check out, and then re-plug like. If each of the inking lines is filled with air, check that the print cartridges leak and replace the ink cartridges (in most cases, the cartridge labels are not sealed).
Welcome to contract us !
With the epson fifth generation head of the shortage of supply and the price soaring, the market has launched the use of epson5113 print head digital printing machine (5113 for the eposn5113 desktop printer used to print the name of the head). 1. Epson five generations of the first reason is because Epson on the five generations of the first encryption, resulting in shortage of supply, the price soared, once the five generations of head out of stock, the use of five generations of users will have to phase out the equipment. 2. Because of the status quo of the five generations of the first 5113 print head by the equipment manufacturers optimistic, plus 5113 print head in the print speed is better than the five generations of the first ,so 5113 printhead is a creative ideal to do sublimation printing .
