Refilling instructions for Canon 445, 446 cartridges
Place some paper towels on the table and place the cartridge on them with the print head down.
Gently pick up with a sharp blade and carefully peel off the self-adhesive sticker with the cartridge number from the surface of the cartridge. She will still be useful to us
Under the sticker there are holes through which we will refill the cartridges, we need to enlarge them with a drill or an awl about 4 mm in diameter so that the needle from the syringe can freely enter it
The sequence in which the colors in the Color cartridge are refilled: yellow is refilled first, magenta second, and blue third; this is necessary in order to minimize the negative consequences of possible mixing of ink in the cartridge head during refilling
Having collected ink into the syringe, insert the syringe needle through the hole into the foam adsorber and slowly injecting ink, fill it. The approximate volume of ink for a color cartridge is 2.5-3 ml per color, for a black cartridge it is 5.5-7 ml. When ink appears on the surface of the adsorber, pump it out a little with a syringe, excess ink can only harm.
It is recommended to insert the needle at an angle of 45 degrees so as not to damage the print head of the cartridge from the inside.
Be careful NOT to touch the cartridge chip with your hands, and also do not stain it with ink. Even an imperceptible contamination of the contact area of the chip can cause the cartridge to malfunction.
After filling all the ink cartridges, wipe them dry with a paper towel and, if necessary, wipe the contact pads of the chip with alcohol. In no case do NOT use eau de toilette, colognes or other perfumery products for this, as they contain various aromatic oils.
Now that the cartridges are filled and dry, reattach the labels and reinsert the cartridges into the printer.
We recommend that you clean the print head through the printer software from your computer before printing.

Also, additional consumables are produced with a resource of 300 and 400 pages of color or monochrome printing, respectively. These cartridges can be identified by the presence of the letters XL on their labels. The cost of original cartridges with a large capacity is comparable to the cost of the printing device itself. You can solve this problem by learning how to refill the cartridges yourself or by installing CISS.
What if you need to urgently print monochrome text, and the printer refuses to do this because the color ink in it has run out? This problem can be solved. In the Canon My Printer application, you must select Black Only in the Cartridge Settings and the printer will print. A color cartridge can also perform a couple of pages of monochrome printing.
Preparing for refueling. Refueling is recommended at the end of the ink (approximately 5%) in the cartridge. If the ink in the cartridge has run out, it must not only be refilled, but also zeroed on the printing device. Prepare for refilling ink that are compatible with this device, 4 medical syringes, napkins or paper towel, gloves and a utility knife. Turn off the all-in-one printer, then the cartridges will move out of the parking space and you can get them out. Important: The printer must be unplugged before removing the cartridges.!

In this manual we will try to explain how to refill CANON PG-445 CL-446 cartridges,
These cartridges are used in Canon PIXMA iP2840, MG2440, MG2540, MG2940, MX494 printers
To refill these cartridges, you can use the following inks, it is also advisable to use OCP RSL flushing fluid when refilling cartridges
Before refueling, after you have just removed the cartridge from the printer, you need to prepare it for refueling and remove the sticker from it, which is located at the top of the cartridge
After the stickers are removed from the cartridges, you can see the system of air channels and air holes through which we will refill the cartridges. You should NOT try to push the needles into these holes as they are, if you do this, the needle will enter very tightly and pressure will build up in the cartridge during refueling, and ink will flow out of the printheads. Therefore, before refueling, the air holes must be widened with a drill or awl. Drills 1.5-2mm are perfect, after you have drilled the hole, you can start refueling. On the starting black cartridge, which you got with the printer, the air hole is located in this place
For drilling, I personally prefer to use a screwdriver with a 2mm drill bit
Likewise, you need to drill 3 holes in the color cartridge, then you can start refueling. The colors in the color cartridge are arranged as follows
After everything is prepared, we need to draw ink into the syringes for refueling. For the color cartridge, we only need 3 ml of each color, for the black cartridge. 8 ml. There is a sponge inside the cartridges, so Do not be afraid that when drilling into the cartridge, plastic crumbs will get inside, when refueling, you need to pierce this sponge about 1 cm, you immediately feel it when you lower the needles into the cartridge.
After you have refilled the cartridges, you can stick the sticker in place
Before installing already refilled cartridges into the printer, it is advisable to clean the print head of the cartridge using the OCP RSL flushing fluid, for this Turn the cartridge with the print head up and pour a little flushing fluid on it
Then attach a toilet paper or napkin folded in several rows on top
Wait a while until the flushing fluid and ink from the printhead are absorbed into it and Wipe the printhead
Well, that’s all, the print head is cleaned, the refill cartridge is ready for further use.
Also, after refueling, there are problems of the following nature. It would seem that we have refilled the cartridge, and the printer displays a message that the cartridge is out and refuses to print, and does not even pick up paper. No need to be scared, this is normal! Fortunately, in Canon printers Difficult ink levels can be turned off, and quite simple! To do this, you need to hold down the STOP button on which a “triangle in a circle” is drawn and hold it for about 30 seconds after that the printer will stop swearing at the finished cartridge and continue printing. On all Canon printers, this button looks something like this
