 Hi, this is Kevin. Today, I'm just showing you how to use the repair kit for the Canon printer. So the fourth thing is, as you will need to check if the small plug is unplugged. So the first thing we do is I will do a nozzle check. So in the nozzle check, you can see there's no black and there's no white. Go back to the control panel and we'll do a deep cleaning. Do not do this regular cleaning because it doesn't do much. So you go to deep cleaning. So if after the deep cleaning and the result is still not good and we need to bring out the repair kit. The repair kit has a pair of gloves. It has two rubber pads. The rubber pads, the longer one, there's a short one, then there's a long one. The longer one is for the black and the shorter one is for color and then there's a clip and there's a 10 mil syringe. The fourth thing we do is put the gloves on and we're going to use this container to catch the ink. So depending on what cartridge you work on, you're gonna either use a black or color. In this case, we're going to use both. So we put the black pad on the clip, take out the cartridge. We're going to work on the black first. You can see there's a guard on the both side. So you kind of put it in the middle, put it in the center. And your action is you actually push it the inside and down and it should be secured and now slowly you're going to draw the air bubbles out of cartridge and you can see the air bubbles. That was stopping from printing. Okay, then you see the air bubbles and now you can remove the clip and use the paper towel to clean the bottom of the cartridge. Now we're going to work on the color one. For the color, I need to switch the pad. Again, we put the cartridge in the center and push down and then push forward. Okay, and the same thing we're going to draw the ink with the bubbles out. You can see how much air in there. So you can see it's all bubbles. Now I can install it back. Just make sure the tube is now twisted. And when you put it in and it's hard, if you find it's hard to close because of this tube, you can tuck the tube inside a little bit. Then close it. Now I go to another nozzle check. Another deep cleaning. Okay, so this is after the deep cleaning. Let's see here's what we got. Let's start from this and then we get a deep cleaning using the building function. And then we use the repair kit to repair it because after repair and probably we wiped the cartridge too dry so the middle doesn't have any ink. So we did another deep cleaning. And this page number five, which is perfect. Now I'm going to print a full picture.
