Users have little attention to the ink cartridges used when using inkjet printers. The common operation is to install replacement ink cartridges, and few people will carefully study the structure and work of the ink cartridge. The market share of Epson inkjet printers is very high. The structure of its ink cartridges is also very special. Most ink cartridges have IC chips. On the one hand, in order to monitor the use of ink, on the other hand, in order to maintain interests, avoid forgery and production. Compatible consumables. Here, the T027 color cartridge used in STYLUS Photo 925 is used to tell you to the structure of the cartridge.
There are two kinds of color ink cartridges, one is to make all color inks in a box, and the ink in the box is different in the box, and the T027 is this structure. Another kind of each color is made into a cartridge, and each color ink is independent of each other and is unaffected.
The ink cartridge is also divided into the integral ink cartridge and split ink cartridge from the structure. The integral ink cartridge is also made on the ink cartridge. When the ink cartridge is replaced, it is a new nozzle, and the disadvantage is the manufacturing cost. Height; the split cartridge is separated from the ink cartridge and the nozzle without replacing the nozzle, and the advantage is that the manufacturing cost is small, but the nozzle is not easy to repair, and T027 is a split cartridge.
There is a colored strip on the T027 ink cartridge, which will be mentioned in the product manual, inform users, do not tear this seal, to avoid ink leakage. This strip is used for sealing, which is covered is the injection hole of the ink cartridge, and the manufacturer is encapsulated in the ink cartridge by this injection hole. The torn strip can be clearly seen to see two small holes.
There is also a small hole in the lowermost end of the ink cartridge, which is the vent hole of the ink cartridge, and the ink cartridge has a balance in the air pressure in the air hole, so that ink in the box will flow out. The lowermost part of the ink cartridge is ink outlet, and 5 round holes are arranged in parallel, the 5 round holes are connected to the ink port on the printer, and the ink flows from here to the printer.
T027 The most conspicuous place is the front IC chip. This chip does not have any association with the ink cartridge. It can be seen from the figure below that the chip is simply embedded in the ink cartridge, and there is no connection with the interior.
In fact, the monitoring of ink in the Epper ink cartridge is not generally imagined, directly monitoring ink, but detects printing tasks, which is not related to the ink. When we perform print tasks, the printer converts the workload into ink consumption information and writes this information on the chip. For example, a chip can print 10 million standard points, one task needs to consume 200,000 points, the printer will be reduced from the total number from the total, until the number of points is 0, the print cartridge cannot be used, regardless of the ink cartridge Is there no ink. The vendor will more note the actual amount of ink, which is greater than the value of theory, so it is often the printer suggestion without ink, but there is ink in the ink cartridge. The upper cover of T027 can be seen, and the inside of the ink cartridge can be seen, each color is independent in the ink cartridge, the space is the same. There is a variety of cotton in each small slot. They act into the action of the ink, which can be very stable to adsorb the ink, not flowing, so that the smooth to the printer is transported, not too much or too little. .
The ink cartridge has a lot of places worth studying in the design. I hope that the above introduction will make everyone open their eyes. I will see the structure and how to work in the future.
