BCI-2 1 filling water is the simplest in Canon ink cartridges. Pull the ink cartridge forward from the nozzle seat, invert it, and drop the ink directly on the sponge at the ink outlet. When the sponge absorbs ink quickly and the ink absorption speed is obviously slow, you can stop adding ink. The only thing to pay attention to is not to fill it too full, which will exceed the capacity of the sponge, so that the ink will overflow from the vent above. BCI-2 1 Black doesn't matter, just wipe off the spilled black water; BCI-2 1 color ink cartridge is a three-color ink cartridge. Although there is only one vent hole on the upper cover, there are three vent holes on the upper cover, one for each color. Since the three vent holes can't be wiped, once the ink cartridge moves forward, the spilled ink will cause mixed color, so the ink cartridge will be scrapped because of mixed color (if the color is not concerned, it can be used).
In the same way, Canon also has BCI- 10/ 1 1 black/12 black/12 color ink cartridge of BJC-30/50/80/85 printer.
How to add ink to Canon's ink cartridge with nozzle? What are the precautions?
There are two common types of Canon ink cartridges with nozzles. There are one kind of ink injection holes (air holes) on the side: black BC-0 1/02/03, color BC-05/06/09; Ink-jet holes (air holes) are another type: black BC-20/23 and color BC-22/22e/29F. Ink injection hole is used to add ink during production. There is a small hole on the sealing plug as an exhaust hole to keep the internal and external pressure balanced. The structure and inking mode of the two ink cartridges are basically the same. Insert the small hole of the vent hole twice with the attached drill, hold it, and gently pull out the plug on the vent hole. The color ink cartridge needs to judge the color with a toothpick, insert the ink injection needle into the hole to inject ink, and then press the plug back. It should be noted that: first, the amount of ink added should not exceed the capacity of sponge, otherwise it is easy to throw ink when printing; Second, when adding ink, don't overdo it, control it well and avoid overflowing, especially color ink cartridges. Several colors of ink injection holes are close. Once the ink overflows and penetrates into ink cells of other colors, the ink cartridge will be unusable due to mixed color. In addition, there are two styles of BC-03 ink cartridge, one is mentioned above, and the other is with a transparent ink storage cavity on the side, and the ink injection hole on the cavity wall is sealed with steel balls. Its ink filling method is to press the steel ball into the ink storage chamber with the attached ejector pin, and then seal the ink injection hole with the attached new steel ball after ink injection.
HP black ink cartridges with airbags are C 1843A, 5 1625A, 5 1629A/G, etc. The common method of adding ink is to drill a hole in the ink box, plug it with a plug after adding ink, and then adjust the air bag pressure with a syringe. The disadvantages of this method are: on the one hand, fine debris easily falls into the ink box when drilling, and on the other hand, more auxiliary tools are needed.
The patented filling method of this ink box is: connect the attached hose to the ink bottle mouth, connect the nozzle with the ink injection hole at the bottom of the ink box, squeeze the ink into the ink box, and loosen the bottle several times during the extrusion process (don't loosen the butt joint of the nozzle) to let the air flow back. After adding ink, keep the ink cartridge upside down, and use an empty bottle to draw a proper amount of air from the ink injection port, so that the ink will not seep out from the ink injection port after the ink cartridge comes over. It should be noted that when filling ink, the ink is added to the ink cartridge, and the ink cartridge is positive pressure. At this time, ink will seep from the ink injection hole and nozzle, so it is necessary to pump out a proper amount of air to keep the air pressure balance inside and outside the ink box; However, the air should not be pumped too much. If it is pumped into negative pressure, it will cause poor ink output and disconnection during printing.
How to fill HP 5 1645A/G ink cartridge? What are the precautions?
There is a black round sticker on the bottom of the 5 1645A/G ink cartridge. Remove the label and you can see a steel ball. Press the steel ball into the ink cartridge with the attached plastic ejector pin. After a bottle of ink is squeezed into the ink cartridge, clamp both sides of the ink cartridge with the self-contained C-type, tighten it hard, press the new steel ball into the hole, loosen the C-type clamp, stick the sticker back, and wipe the nozzle with a paper towel to let the ink seep smoothly. It should be noted that before pressing the steel ball to close the ink injection hole, the ink cartridge must be clamped first, so that the ink cartridge will have a slight negative pressure after pressing the steel ball, otherwise the nozzle will overflow.
