Do You Know Continuous Ink Supply System for Large-format Inkjet Printers (1)?


I. Overview
1 Concept of interconnection
Continuous ink system for short, it is in recent years in the field of inkjet printers to appear in the new ink supply. The continuous ink system, which uses an external ink bottle to be connected to the printer's cartridge, so that the ink bottle will provide ink to the ink cartridges, is so-called "company." The biggest benefit of the continuous ink system is that the price is much cheaper than the original ink. Second, for the large amount of ink, add ink convenient, general color capacity of 100ml, than the original ink cartridges at least 5 times times more. Its three even for the quality of ink is steadily rising, better even for the ink will not block the nozzle, there is a break to clean several times on OK, which provides a strong guarantee for the survival and development of the company.
2 Principle of the system
The system uses the siphon principle, which is that in two containers with liquid and connected by a siphon, the liquid always flows from the high pressure container into the lower pressure container. We know that in the printing process printer cartridges will flow to the nozzle ink, in the delivery of ink, the ink cartridge pressure is also falling, need to inhale the same volume of air to maintain pressure balance, the system is to replace the air from the cartridge vents with ink, and the ink cartridge is also added to the same capacity when it is conveying ink to the nozzle. Ink, supplemented into the ink cartridge in the external large-capacity cartridge through the hose to transport, external cartridges can be readily replenished ink, This ensures that the ink cartridges in the printer are always supplied with enough ink for the printhead. In addition, some also appeared a kind of use fluid mechanics principle of the automatic ink-supply system, according to the manufacturer, its ink supply than siphon system more stable, and can be applied to all types of inkjet printers, the actual effect of this product has yet to be tested.
II. System Structure
The system is made up of three parts, such as external cartridge (ink bottle), hose and bracket, inner cartridge (ink sac) and so on.
1. Outer cartridge
The outer cartridge is a large capacity ink container that is placed outside the printer and is usually molded from plastic injection molding. The external cartridge capacity is larger, usually each color is above 100ml, also has specially prepares for the home user small capacity to connect the system, outside the cartridge each color capacity is approximately 50ml. The outer cartridge is usually provided with a ink hole to facilitate the addition of ink, there is also a vent hole to maintain the pressure balance inside and outside the container. For the outer cartridge, the control ink liquid level is a very important problem, the ink liquid surface height will cause the external cartridge pressure too large, so that ink flow into the printer's waste ink warehouse in vain, and the ink liquid surface too low will make the ink cartridge in the pipeline to the outside cartridge backflow, resulting in air from the print nozzle into the inner cartridge, so that the ink cartridges produced tiny bubbles, and these tiny bubbles will cause the phenomenon of print disconnection. In order to avoid these problems, usually require the outside cartridge ink liquid surface to be slightly lower than the printer nozzle, but with the consumption of ink, the ink cartridge inside the liquid surface will continue to decline, which requires timely adjustment of the height of the outer cartridge, or at any time to add ink, in order to solve this problem, many manufacturers are on the outside of the cartridge design voltage regulator device, such as some manufacturers use the spring, and some manufacturers use the principle of atmospheric pressure in the ink cartridge to add a balance between the automatic pressure, so that you can maintain a constant liquid level. The use of an automatic pressure regulator outside the cartridge is called the constant pressure cartridge, it can be directly fixed on the printer shell, moving up is also very convenient.
2. Hose
Hose also known as the pipe, it is the outer cartridge to the inner cartridge to carry ink pipeline, it is actually a group of siphon, the external cartridge and the ink cartridges in accordance with the color of one by one connected together, for the convenience of walking line, hose is usually 4 or 6 sticks into a row, hose may also have a variety of brackets or fixed blocks to facilitate installation fixed. In addition, some manufacturers also add the ink control valve on the hose to control the ink switch and flow size.
3. Inner Cartridge
The cartridge inside the printer is called the inner cartridge, and its size and shape are similar to that of the original cartridge, which can be installed in the printer's ink car to replace the original cartridge (also useful for the original cartridge modified in the inner cartridge). The inner cartridge cannot be used universally, and a specific model of the inner cartridge can only be installed in a specific type of printer.
Inside the ink cartridges in the system is a very important part, not only to ensure the continuous and smooth ink supply, but also to eliminate the phenomenon of ink leakage, which is the design and production of ink cartridges. More than 09 years of the inner cartridge is mostly used without cotton cartridge, and there is a cotton ink cartridges, its ink is not easy to produce bubbles, the air is difficult to enter the nozzle, installed, take the cartridge after the disconnection problem will be reduced, the life of the cartridge is also longer, its shortcoming is easy to leak ink There are some manufacturers of ink cartridges and did not use the conventional ink cartridge design, but the use of ink bag, almost is the hose directly connected to the ink cartridge out of the ink, this design allows the installation of cartridges more easily, the line is more convenient.
All the connecting system or automatic ink supply system is composed of these three basic components, the difference between them is mainly inside and outside the internal structure of the ink cartridges, there is the difference between work and modelling. Even the system is basically a "details determine success or failure" of the product, in many cases, we can distinguish it with the naked eye, good and bad, even for the system must be a good material, fine workmanship, beautiful appearance products.

III. System Ink
There are many kinds of ink, and there are two main types of ink:
1, if according to chromophores classification, ink can be divided into:
Dye-type inks (dye)--the ink that is chromophores by dye--is also the ink used by most inkjet printers.
Pigment inks (Pigments)--inks that are chromophores with pigments.
2, if the ink is in accordance with the solvent to distinguish, then divided into:
water-based ink-water and water-soluble solvents as the main components of dissolved chromophores.
Oily ink--a water-soluble solvent as the main component of dissolved chromophores.
The above concepts intersect with each other in the actual use process, for example, some pigment inks may be water-based ink can also be oily ink. However, from its own nature and the actual requirements of the printer, water-based ink and oily ink is absolutely not allowed to mix in the same print head.
Ink shelf life generally for two years, the preservation of ink requirements sealed to avoid direct sunlight, the temperature should not be too high or too low (normal room temperature can).
Factors affecting printing effect and printing head performance
1, viscosity and surface tension:
Viscosity is liquid flow resistance, liquid surface tension is related to the formation of droplets, in general, inkjet ink to have a low viscosity, high surface tension to ensure good flow performance and droplet shape. The surface tension of LJ ink is generally
2, Ph value:
The concept of liquid ph, the more acidic the solution, the lower the ph value, conversely, the more alkali the solution, the higher the ph value. In order to prevent ink corrosion nozzle, ph value should generally be between 7-12. The ph value of AJ ink is generally between 7.0 and 8.0, which is almost neutral.
3, conductivity:
In ink, the conductivity value is used to reflect the level of salt content. In general, the salt content can not exceed 0.5%, in order to avoid the formation of crystallization in the nozzle, AJ ink salt content is less than 0.3%.
4. Dispersing Agent:
A kind of surfactant, its function mainly is to improve the ink surface physical properties, enhance the affinity and wettability of the ink and sponge. So generally through the sponge storage, conductive ink contains dispersants.
Most of the general supplies in pigment ink and dye ink on the fuss, many Epson printer is pigment ink, because the production process of pigment ink is relatively difficult, so the majority of domestic general supplies are used dye ink to replace. Printer Ink Pigment Introduction will also bring a certain impact on the ink market. But the price of pigment ink is still high, dye-type ink or dominate the market
。 Of course, the general consumables manufacturers can also make pigment inks, but the price is relatively expensive, so in the purchase of inkjet printer general consumables must pay attention to this point.

IV. Installation of the connecting system
1,Pre-installation Printer test
(1) Test whether the printer is working properly, check the mechanical state of the ink car and lubricate the condition.
(2. Print nozzle test line to check the printer nozzle is normal. Prints the picture and tests whether the print effect is normal.
3. If the test is not normal before the installation, that is, for the printer itself, please contact the seller or after-sales service department of the printer to solve the problem after you install this product.
II. Installation method
1. Straighten out the continuous ink system to guide the ink tube, the external cartridge storage bin to the lower level to eliminate the balance of air. (a pen can be padded below to ensure the level of the air compartment)
2. Erect the outer cartridge, open the inlet cover, install the air filter.
3. Press the printer to change the ink key, when the ink car moved to replace the cartridge location, unplug the power cord, remove the original cartridge. Streamline the guide ink tube, install continuous ink cartridges, cover the ink cartridge gland. (Note: Some models of printers, such as C63, R210 can be removed from the cartridge lid.) )
4. Remove the bracket in the attachment, set the printer in an appropriate position, move the ink back and forth, adjust the length of the cartridge pipeline. Ensure that the printhead is not obstructed within the range of motion. Find the most suitable position of the bracket, tear the adhesive on the bracket and fix the bracket. (Note: Again, this time the printer's power cord must be unplugged or it will affect your printer.) ）
5. After checking, plug the printer power, press the ink-exchange key to reset the printer, check the length of the guide ink tube, then enter the printer nozzle check option, print nozzle test line to see if normal, such as normal printing. If it is not normal, please do the print nozzle cleaning procedures, after cleaning for 20 minutes after the use of better results.
III. Considerations
1. This system uses the constant pressure system, must maintain the outer cartridge balance cartridge ink liquid noodles or more than 1.5cm.
2. Please keep the external box of the system and the printer on the same desktop.
3. Please select the company's special matching inks, the ink is carefully developed, rigorous testing after the selection. The ink can be used with the system to achieve the best printing effect.
4. Please install in strict accordance with the operating procedures: First take off the air intake Konseizo after the installation of cartridge. So as not to cause bad printing.
5. Please note the ink in the outer cartridge, if the liquid surface and the bottom only 1.5cm, please add ink in time. After adding ink, the air inlet ink liquid surface height should not be greater than 1.0cm, otherwise it will affect the pressure.

V. System Exhaust
First step: From the printer to take out the ink cartridges, together with the entire set of ink bottles to take out, placed on the same level, and then turn over the cartridge, let the ink mouth up, and then use the object slightly up the ink cartridge out of this end, that is, cartridge ink in the bottom, sponge warehouse on. Note that there is enough ink in the ink bottle.
The second step: here to give the blue ink cartridge exhaust As an example, unplug the blue ink bottle blowhole filter, find a medical 20-30 ml syringe, unplug the needle, pull up the piston, and then put the syringe outlet into the ink bottle blowhole, the purpose is to be pumped from the blowhole.
The third step: to find a medical 20-30 ml syringe, the needle does not need to be pulled out, the piston does not have to pull up, and then put the needle nozzle in the blue cartridge out of the mouth of the sponge, the purpose is to smoke from the ink out of the mouth.
Step Fourth: The above three steps for the preparation work, this step officially began to exhaust the ink, then the best of the novice with two people, a people first slowly push the syringe on the ink bottle piston to air vent, then will see the blank pipeline soon filled with ink, and cartridges ink cartridge into the ink gradually rising, then the air from the ink cartridge out of the mouth, entrainment a lot of ink blisters, at this time another person hurriedly with a syringe to draw out the ink blisters, do not let the ink out of the bottom of the cartridge chip. In this way until the ink cartridge ink is full, the ink cartridge out of the ink is basically not entrained bubble ink outflow, you can unplug all the syringes, exhaust ink is finished.
Step Fifth: You can put the cartridge back to the printer, remember to lock the pipeline first, the ink bottle is not locked, then use the clamp to clamp the pipeline, then put the cartridge back to the printer, and then release the tube clip. This will prevent the cartridge from moving even higher and lower when the connection is moved, resulting in an imbalance in the supply of gas and internal pressure. (Hint: If just exhaust ink is finished soon, the pipeline is white again, explain even for leakage phenomenon, please find out the cause of leakage and then new exhaust ink. ）
