Please do the following steps in refilling Canon PG-41 Color Ink Cartridge. Canon PG-41 is a sponged color ink cartridge and therefore, it has to be refilled with a needle from the holes located on the top and under vacuum in a vacuum chamber. Due to the sponge inside the cartridge, it is crucial that the air should be removed prior to refilling and then the ink can be filled. Otherwise, because of the existing air bubbles inside the sponge, cartridge stops printing after several print outs. Furthermore, we cannot refill the original ink volume.
1. Steam the print head with Steam Generator Machine and apply the steam for approximately 10 seconds. It is crucial that the steam gun should be pointed in a perpendicular position. As for all color cartridges, you should point the steam gun far way from the print head for better results.
2. Fix the cartridge into the refill clip and connect to the waste evacuation line. In MIS ink cartridge refill machines, vacuum chambers can also be used to take the waste ink out. In order to do that, connect the cartridge, which is fixed into its refill clip and start the vacuum compressor. While the compressor runs and removes the air inside the chamber, the waste ink will be evacuated, as well.
3. Work with a knife and peel the cartridge label off. You can use steam generator to soften the glue of the label so that you can easily remove it. To do that, simply apply the steam through the side of the cartridge and from the corner of the label. Put the cartridge into the vacuum chamber and insert the refill needles through sponges as shown in the image.
In order to see how to connect and refill in different ink refill machines, please refer to the “Ink Refill Machines” menu on the left.
4. Refill 5 ml of each color ink, i.e. Cyan, Magenta, and Yellow.
5. Remove the needles and take the cartridge out of the vacuum chamber.
6. Get a clean and dry tissue and wipe the print head. Afterwards touch the print head to the tissue quickly one after another and check whether the ink is coming. If you see 3 color lines on the tissue as shown in the image, it means that the nozzles are open and if there is nothing wrong with the electronic circuit, the cartridge will print very well.
7. Fix the cartridge into the printer and get a test print out. It would be a good idea to make a new Word document, which has a content of some text and bold rectangles. For a sample page, please click here. If you get your print out from this Word document, you will be able to see the printing performance of the refilled cartridge.

8. If the print out test is satisfactory, then we can switch to sealing and packing. In order to prevent the ink from drying, we put a drop of cleaning solution on the print head and wipe it with a clean and dry tissue and fix the cartridge into universal transport and protection clip.
Alternatively, you can put a small piece of blue tape over print head. It is crucial to know that in order to prevent any ink dripping, wipe your finger around the print head. Otherwise, the air left between blue tape and print head will make an air pressure and pull the ink out of print head. Such a result will lead ink dripping and drying as the time passes. While sealing the print head, put a “Remove Blue Tape” label between blue tape and print head.
9. Eventually, put your refill cartridge in a plastic bag and seal the bag opening.
