 Hi, this is Kevin from BCH. Today, we're going to troubleshoot one of the customer's questions. And maybe you can be a detective and just walk through those stuff with me. The customer bought our Spongebob Refill Kit for $2.45 to $4.46. Basically, here's the problem. So he installed the refillable cartridge in the printer. And he put 10 mils in the black and two mils in each color. And it works at first. So did a couple cleaning cycles. And everything is fine, except I was missing one yellow. So right now, here may be two things. One thing is for the refillable cartridge, 10 mil for black is kind of a half of tank because the refillable cartridge take at least 15 to 20 mils for black. And the color, they only put a two mil for the color. And this is a little bit too little. So maybe that have something to do with didn't print a bar of yellow. Or maybe the nozzle is blocked. So here we know what to do. First thing to do is put more ink. Put it until you fall. We're talking about refillable cartridge here. And now the original cannon. Original cannon you want to put the two mils rather than five mils for color. So that's over plan A. It's make a refillable cartridge. I fill it all the way. And unclog it using the primer. And then he put the original back. And they have all colors, of course. So it's cannon cartridge. They should have all colors. And then he put refilled black, refilled cartridge back. And it stopped printing and says no ink. Now the refilled shows no ink. So what he did is he tried to hold down the stop button for five to 10 seconds. And tried it about eight to 10 different times. And nothing happened. And it said, on your block, it shows direction for a different way. With printer on, hold down stop button for five seconds. Power off printer. Hold down stop for another five seconds. Still holding the button pressed for five times. I don't remember this on our blog. So here's the problem again. Low ink, it doesn't matter. The low ink, you have to print until window pops up. And then with that window open, you go hold down the button. With low ink, nothing going to happen. So no matter how many times you hold down to the stop button. So this is why. So he tried about six more different times. So basically, on hold down the button, I'm powered a printer and powered it back, which is basically, you don't need to do that. We're going to, here's what we're going to do. We're going to show you one cartridge has low ink. One cartridge is depleted. Then we'll show you how to reset them. So basically, he didn't reset it. And then he started. Then he filled the cartridge and put a quarter of mils of air in each hole, which he's trying to unclog. And then, basically, he don't know what to do from now on. OK. I think we got a plan here. First thing is, we tried to mimic what he did. And we put only, then we're going to make a refillable cartridge. Then we're going to fill it up all the way, not with 10 mil and 2 mil. We will fill up the cartridge. And then we unclog it, so make sure it's working. And then we're going to print more pages and show you how to reset it. And I think that will cover all the questions here. Oh, by the way, actually, I called this customer. And here's another issue is the customer was using the wireless connection, which is not USB connection. So with the wireless, the different airs pops up. And I suspect the wireless didn't have good connection. So when you print it, it doesn't print. But for you to troubleshoot it, it's better to just use a USB connection and just make sure that it has good connection. So it can make sure you have good connection. So you don't compound with how to disable the router and just all those stuff. OK. So today, actually, I set up a wireless connection. I set up a wireless connection with, here you can see the color cartridge is steady yellow. That means it's low ink. And the black cartridge is blinking. That means it's depleted. Actually, what you need to do is actually go to the, I'll use iPhone. You can use your Samsung or Android phone. So go to your app store. And you'll search for Canon Print. So then what you do is you add a printer. And you'll register a printer. Form a wireless LAN setup. Then you manually select connection type. Then you choose a connector or connect the wireless router. In my iPhone, I go to settings and the Wi-Fi. And I need to get the printer to be able to show a Canon J wireless, what I'm doing is. OK. Some manuals are wrong. They said black. Here is what you do. The start must be steady. Then you hold down this for a few seconds. You can see the start button is stop blinking. Then you press color. Then press the network. Now you can see the network is blinking. And on the wireless, you can see this long Canon IJ177 has an unsecured network. Then we'll connect to it. The connection is successful. Then we go back to the app. So the printer will be connected to the following wireless router. So yes. And then you enter the password. Now I show up this printer. So now we go back to where we were, start setup. Two, three minutes. The first thing is I try to do alignment. We don't really want to do alignment when we do not have good cartridge. For the setup, we say now. And then test print, we just say next. We don't need to test it. And this is a setup come. OK. First we're going to do is to make two refillable cartridges. OK. We're going to use the BZX-ESFC-CB2 spongeless cartridge. The first thing to do is just cut off the black top, the sponge. Now we cut out the color one. Now we use a piece of sandpaper. Now is a good time to wash out the dried ink. You can see on the bottom. Well, steam clean a little bit. The smaller smorin' and towards the top. Don't think we have problem with the black. Black should be easy. We got a silver glue from a 99 cent store. And now the color. My glove become sticky. So I don't want to mess up with those electronic ribbons. I just add a little bit more when I see the air. There are two places you don't touch. One is here. One is here. That looks pretty good. So I'll set it here for at least half an hour. OK. Now we're all ready to address the first problem. Going to add ink to the black one. We add about a 3 quarter full. Actually, if we want, we can just go all the way. How about that? Before I put it in, I'll just give it a little bit of steaming. Just in case. OK. Now what happened is the color cartridge is blinking. And the hazard sign is blinking. That means the connection is not good for the color one. So what I will do is I'll take the color one out. Oh, that's why. I forgot to take this off and make sure it's very dry. Now you can see the color one is steady yellow. Steady yellow means the color is the ink is low. The printer think ink is low. And the black is flashing. That means the black is depleted. OK. We want the cartridge to be depleted. Let's go print out. Let's go troubleshoot the clocking issue first. I'll do a deep cleaning first. All color. And now you can see the color one has a triangle sign on it. And it says ink is running low. And the black doesn't have a triangle. That means the black is depleted. So this is actually the user's second question, is how can I reset the low ink? You cannot reset the low ink. You have to print until the ink is depleted. Otherwise, no matter how many reset you do, how many times you push down the stop button, nothing happens. So if you see you have a steady yellow light. And it says low ink. That's OK. That's absolutely normal. Just keep printing until the ink is depleted. Now we'll print that check pattern. Let's take a look. So you have OK-ish magenta and yellow. So that means the black is pretty good. The black, I will say, is like 98%, 98%, 99% of its prime condition. So what we need to do is unclog the cyan, unclog the magenta, and unclog the yellow. OK, let's do this. OK, I'm going to have a piece of paper towel ready. All I need to do is using this one included in the unit. So I'll blow like 1 ml of air into the output in all of them. You can see the air bubbles coming out. Now what happens is during the refill, we get air bubbles inside the printhead. That's why it blocks. You can see it sort of gets all three colors. And the ink is still dripping because the air I blow the end, it have a delayed effect. I blow too much air in the yellow. So we need the yellow to be set for a second. Maybe I just un-released the actual air out. Now you can see the ink can hold, the cartridge can hold the ink. That's because I put too much pressure on here. So now I put it in and do another cleaning. OK, now it looks like the cyan has a little bit of problem here. And we're going to do the same thing again for the cyan. I think you can see there may be something going on there. So I clean up the top. What I'll do is I'll just like the cyan balances pressure. So I just unplug the fuel hole and plug it back. I'm not going to blow air in it this time. I believe it is because we pressurize different chambers. Some of them have higher pressure. So what I'll do is I'll just unplug everything and plug it back. So the air is all balanced among three of those. I can see that actually the cyan is much better now. So what I'll do is I'll do one more time. I'll blow some air in it one more time. I need to stop the flowing. OK, so now it's perfect. So here's the first part. What should you do when you have straps? So basically, the user what he did is, inside of doing this, it's interesting, he didn't do this part of unclogging. So immediately he put two cannon cartridge inside. So he took the cartridge out. And he put two cannon cartridge in. He print a couple pages. And now after printing a couple pages, he put the refillable cartridge back. OK, I don't know why he need to put the original cannon in. But we just try to repeat what he did. And now the refill one is in. And then he says, both cartridges are not working. So let's try to print a page. You can see still the color one is low ink, and black one is empty. So it's depleted. And you have a pop-up window set. The ink cartridge has to be installed or replaced if the printout contains misalignment or it's not satisfactory or whatever. And here, the only thing you need to do is click OK. And here you go. You're going to have air-code 1686, which is for the black because the black is depleted. Cannon asks you if you want to print on a depleted. And it has to give you the instruction of hold down the button for five seconds. So what you'll do is just hold down the stop for five seconds with that window open to not close that window. So you hold it down. OK. So after this, OK, let's fix this low ink problem. I don't call it a problem because it doesn't have a problem. So right now, the printer believes there's a little ink in the color. So what we do is we're going to just keep printing until the printer thinks the color is gone. So we will run through maybe 100 pages. So the black is nice and blinking where they were resided. So now we only need to work on the color. Now, after maybe 20 pages and it shows support code 1688, the following ink has run out, the color cartridge, CL241. And it asks you to press the stop button. See the triangle sign and the yellow is flashing. So now we press and hold the stop. And then we'll hear a click and the printer back to work. And now both of them are flashing. So when it works, both of them should be flashing because the ink has depleted. So now you go back. You're going to see the warning sign is off for the color. So now the printer can just work forever.
