 Welcome to BCH Technologies, this is Kevin. Today we're going to show you how to make a Spongebob Refillable cartridge. You can do it on your own startup cartridge or a regular cartridge, Excel cartridge, or you can just go to eBay and search for empty cartridges and you can buy those and modify them. Let's go over what we need. We need a mod kit. Go to bchtechnologies.com and click the mod kit and the mod kit for HP and this is the mod kit for making spongeless. Make sure the pictures are spongeless. Other things you will need are sandpaper, a heavy-duty outdated knife, some rubber bands, a super glue, and a long nose plier. For the ink, we suggest KD600X which you go to bchtechnologies.com go to Refill Ink, Refill Ink for HP and on the left hand you're going to see a filter and you click 600 mil, that's the total amount of ink and then you'll scroll down and find a four-color ink and it has three black ink and CMY. There's a lot of ink. The first thing we do is get the cartridge protected. We use a piece of tape, the sticky parts towards us and the non-sticky parts towards the cartridge. The cartridge printhead will not get in contact with glue. Then we get a second piece of tape and place it on the top of the cartridge and press it down. Then we get a third piece of tape and put it on the electronic ribbon. The third piece is in case there's some super glue drip down and we don't want the super glue to get on the electronic tape. And then if you want, you can sort of bend the tape a little and make a little tab so it will be easier for you to remove it. You can just pull it and remove it. Once the border is open, we'll work on the other sides. Once all the edges are loosened, the cap can be taken off and exposed to the sponge inside. In the next step, we need to get the ink flow into the filter. So what we do is, we use the long nose plier and open up the wall. So the ink outside the wall can flow in. And make sure when you do this, do not damage the filter on the bottom. You don't need to remove the wall completely as long as the ink can flow inside, that's fine. Now we do the same thing for the color ones. Step one, get the cartridge protected. Step two, cutting. So for the color one, we need to make an opening on those four walls. In the next step, we'll use 150 grade sandpaper to sand the top of the cartridge evenly and smoothly. We'll then use a knife to remove the high-end debris. We need to glue this cover airtight. So during sanding, make sure that the top can fit very, very tight. And make sure you sand enough things from the top. And you shouldn't say anything shiny on the top. If you say anything shiny on the top, you didn't sand it down enough. And then you can use a compressed air to blow the debris out. Or just like me, I'm just using the tap water to wet it until I see the filter is totally clean. And this is the best time for you to get rid of the dry ink as concentrated on the bottom. So we're going to apply a labor amount of super glue on the cover. What we do is, for the color one, we fill the center cover and sort of like form a letter T. So the center one is the one that's most likely to have air leaks. And then we apply a layer of glue on the every edge of the cartridge. Make sure we're gloves while doing this. You can see it's a very sticky situation. Make sure you don't accidentally drop any glue here, which is the air hole, that will ruin the cartridge. Then we can use a rubber band to secure the cartridge. For the outside room, we can look in for air bubbles and we can add a little bit of super glue as needed. But for the inner walls, it's too late if we see any air bubbles. After setting it for a couple of hours, according to the super glue's manual, in this case we set it for four hours and make sure it's completely dry. And then we just fill it up with ink. We're going to fill it all the way to the top and just leave a little bit of room for the plug. For the color ones, don't forget your color frequency. That's the color of the sponge when you take it out. Each piece are making trick cartridges which they swap two colors. For example, if you see this manual, I show you the top is magenta and your top may be cyan. If you follow it, then you get two colors swapped. If it's swapped, it's no big deal and just get the ink out and do it again. HP just reached a new level by doing this. They just try to make the refill as hard as possible. And now we're going to show you how to do unclogging. If you have a printer that's working, which I mean it's printing, but the printout is blank or the printout is striped. That means it's clogged, which means you have air bubbles underneath. If you have a priming clip, you can just do like this, put it on the clip and draw some ink from the bottom. The air bubbles will be drawn with ink. And I know not everybody has a priming clip. If you don't have one, let me show you an alternative. So you get a piece of paper towel and the white paper towel with some water. And then get a vacuum cleaner and swap underneath. Once unclogged, you can see lots of ink coming out. Besides those two methods, which are sucking from the bottom, and because you get this thing airtight, you can blow one mil of air from the air hole and keep the refill hole clogged. Because after you're blowing, the air pressure inside is higher, so you'll need to unplug the refill hole and release the air. Your refill cartridge will not show real ink level. So it will show the old ink level, like the black one, or it will show no ink level. So just ignore all the warnings about the low ink level or cartridge ink depleted. Whenever you see an air window pops up, just click OK. And it will dismiss the message and keep printing. So you're OK as long as this ink indicator light is not flashing. When it is flashing, there's something wrong with your cartridge. Maybe you broke the filter or maybe something as simple as there's some ink splash on the ribbon, so you'll need to wipe it dry. So take the cartridge out and re-insert a couple of times. If this light is still flashing, then the cartridge is permanently damaged. Our first printout looked weird. It looked really dirty and we tried to use the printer's building function to clean it. We cleaned twice, so it has those weird stripes. Then there's a hot moment. We forgot to remove a piece of tape from the bottom. After removing the tapes, you can see the black is still clogged. So we use the vacuum to suck it a little bit more and see if we can remove the clog. You can see the result. There's a significant improvement of the black. Then we just keep doing it until the clog is completely resolved. Because the ink indicator will not tell us how much ink in the cartridge from now on, it always shows low ink or ink depleted. So what we do is we just ignore it and just click OK every time. Every time it shows us the warning. After you click OK, the printer will like to keep printing. Keep an eye on the printout and add the ink as needed. We print enough copies to let the printer show that both inks have depleted. Now we're going to fill it up to the max level. And then we're going to print and see how many copies we can print from one review. We're going to put a green tab for every 50 pages printed. Finally, the ink runs out. And let's see how many pages we have. We have 400 and here's where it starts right now. We printed 407 pages. And now we can refill the cartridge and print it again. So if you just refill the original, you're going to be able to print 100 pages. And if you upgrade the cartridge to make it larger, you can print about 269 pages with a sponge refillable cartridge. And if you do this sponge less, you'll be able to print about 400 pages. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Winsborough, North Carolina. Have a good day.
