How to refill a Canon cartridge

Every owner of an inkjet printer inevitably faces the need to refill his cartridges. Of course, it is wiser to spend money on a continuous ink supply system (CISS) once and then only monitor the presence of ink in the tanks.

Most inkjet cartridges do not require refilling after emptying. Nevertheless, this does not mean that you need to extract 1.5-2 thousand rubles from your wallet and buy a new cartridge. If you had to do this, no one would buy these printers because of the huge cost of printing.

Today we will look at the process of refilling Canon MG 2540S printer cartridges. First color CL 446 and then black PG 445.

And at the end of the article, I will demonstrate everything said below in the video version on my YouTube channel

For this, we do not need so much:

- drill with a diameter of 2mm

- drill or screwdriver

- 4 ink cans (colors: black, magenta, blue, yellow)

- 4 syringes

What ink to take? Better of course the original. But to be honest, I didn't get it. Therefore, I took from what was ... The main thing is that the manufacturer indicates that the ink is suitable for your model. Yes, and the advice of the seller will not be superfluous to listen to.

And so ... The choice is at your discretion ...

Let's go further!

Open the cover that gives us access to the cartridges. Slightly press down and pull towards you, as in the photo below.

Let's wait until the carriage with the cartridges leaves, stopping in this position (pictured below).

On the left is a color cartridge, on the right is a black one.

Remove the color cartridge.

Lightly press down on the front edge of the cartridge. Now we pull it towards us. Pulls out effortlessly.

Without unnecessary emotions, we calmly raise the label. You don't need to completely tear it off. Enough to be able to access the three filling holes.

Each hole is assigned to a different color: Blue, magenta (pink), and yellow.

We draw the appropriate ink into the syringe (from 2 to 4 ml). We go by flowers. Do not confuse, otherwise the result of printing will surprise and upset you a lot.

After refilling all three colors, we return the cartridge to its place: we move it forward until it stops, and then we lift the front part up until it clicks.

Now take out the black cartridge. The principle of extraction is the same as with color.

My black cartridge has never been refilled.

To be able to refuel - you need to make a small revision.

After removing the sticker, you need to drill a hole in one of the cavities with a thin drill. I had 2 mm. But it can also be thinner. The main thing is that the hole then allows you to enter the syringe needle.

Now draw up about 5 ml into the syringe. ink and ... refill through the hole. After that, the sticker is returned to its place.

If the sticker does not stick or you have somehow ruined it, torn it, use tape or insulated tape. In any case, the top surface of the cartridge needs to be sealed with something so that the ink does not dry out.

Return the cartridge to its rightful place, close the lid and ...

…. and now you need to press this button for 10 seconds (a red triangle in a red circle).

After that, you need to calibrate the cartridges programmatically. This feature is available in every printer software. Even if you do not do this, the computer will notice that you have removed the cartridge and offer to calibrate.

Although... I don't. This does not affect the print quality.
