Today we're going to troubleshoot an Epson WF-7610, equipped with a continuous ink supply system. We'll cover troubleshooting CIS, installing, and priming refillable cartridges, as well as diagnosis and unclogging printheads. The first problem is the printer complains about not recognizing all the cartridges. Many people would open up the printer lid and start troubleshooting. The correct way is to click the proceed button and then open the lid. We'll wait until the cartridge comes to a stop. Then, press and hold the reset button on the CIS.

The reset button will discontinue the electronic currency on the chip temporarily and thus for the printer to think. As the button is pressed, the corresponding symbol on the LED screen is grayed out. Once we release the button, they'll light up again. We'll push the check button and make sure the cartridges are installed correctly. After closing the lid, Epson displays this screen. It looks scary, but I call it a happy screen. When we see this screen, we know Epson is accepting the new cartridge. If you read it carefully, it says, "You are not installed genuine Epson cartridges. Are you trying to save some money, naughty boy?"

The second screen is like a divorce paper. "If you're doing this with Epson, then I'm going to go live with my mom, and I'm taking the kids." Next, there is, "Are you sure?" page. Okay, it looks like our first problem was solved. Let's check on the nozzles and see if there are any clogged nozzles. All nozzles are blank, a piece of blank paper. We'll use the printer's built-in function to clean it twice. Then we'll wait two hours. Then we clean it twice again. Let's do a blank page after four cleanings. We took the CIS out and checked the ink in the cartridges. There wasn't any ink inside any of the cartridges.

We took a syringe, and then we removed the top plug from the cartridge and then drew ink from the tank. If you notice, we already have the tanks open, and we installed air filters on the ink tank. You can see there's no ink coming in at all, so we've used a special adapter on top of the syringe and are trying to draw inks from the bottom, just like how the printer consumes ink. The adapter can be found at the BCH website and called accessories and syringes and needles. This is a four-piece plastic refill needle.

You can see no matter how much we suck. There's no ink coming at all. Once we took it apart, I can see. There's no link. We do not make this CIS. We covered their logo just for courtesy. I'm not a big fan of this kind of CIS. You can see there's a big column in the middle. That column regulates the ink pressure, and I'm more favorable for a split ink design. Here's our split tank design. The tank is divided into different chambers, and I think it is more stable than column one.

We're going to install a new set of cartridges, a refillable cartridge, and the CIS. We go to the cartridge and go for Epson. There is a 252. [silence]

There are two holes. One is an air hole in the back. You unplug this hole and never plug it back. Just leave it open. Then there's a refill hole in the middle, concealed by a clear plug. We use something to poke it in and remove it. The two holes are connected, and if you find one hole is tough to get ink in, you're refilling the wrong hole. You're filling the air hole. Another one is straightforward to get ink in, and you won't damage the printer if you use the wrong hole. It just takes a long time to fill the air hole.

We're going to borrow the plug from the air hole to seal this. The refill hole is sealed, and that air hole is open. The only time you want to seal the air hole is probably you take a cartridge somewhere, and you don't want to spill. Other than that, keep it open. Here's my secret hatch, and it's an optional step. If you happen to have a priming tip, use the priming tip to draw a little bit of air from the bottom until you can see the ink. It's highly optional. Just for me, I like to do that to reduce the chance of getting clogging. If you don't have a tip, you can get one very cheaply from our website. It's under accessories and syringe and needles—this four-piece plastic refill needle tip for quick ink transfer and the priming CIS.

By the way, this is sublimation ink, and that's why it looks so weird. That black looks like a brown. For the sublimation ink, you have to do a heat transfer to show the actual color. Secret ingredient.

Here's one error that we get lots of calls of. Once you install a new set of cartridges and it says the following cartridge cannot be detected, the reason is you probably opened up the lid before you let the printer know. It's pretty easy to correct. Let's click proceed and open up the printer. You can see once you unclick the cartridge, the one on the corresponding LCD panel has grayed out. Once you press it down and that it's lighted up again. I'll unclick the magenta, just for sure. Then it will continue. Then we get this heavy screen, "You have not installed genuine Epson cartridge." Yes, of course, this is not an Epson cartridge. Proceed, and warnings, okay. "Do you want you still use this ink?" Yes. Done.

After we have another check, it turns out that the yellow is clogged pretty heavily. In addition, part of the magenta is clogged. So, of course, we do two built-in cleaning functions, then wait two hours, then do two more. After that, it's still clogged.

We also made some printouts, and we can see the yellow, the clogged yellow. It's time to bring out the big guns. We use this, our triple action cleaning solutions which are at accessories and anti-clogging agent. The triple cleaning solution work on dye pigment and sublimation ink because this ink is a sublimation ink, so we have to use the triple cleaning solution, which is green in color. We turn on the printer. As soon as the cartridge can move, we unplug the printer. We don't want the printer to lock the cartridge, so we cannot move it anymore. Then we'll take a piece of paper towel, put it underneath the ink pad, and then move the cartridge to the middle.

Then we use this tool from accessories and priming clip and syringe. It's this unclogging syringe tool for Epson. But, again, there is nothing special about this tool. It's just a syringe with a tube, but the tube is tested to fit perfectly and tightly with the ink intake, so make sure that, when you pick up a tool, make sure it matches the model. Otherwise, you may have a bigger tube, and so the ink will be everywhere when you use it.

We fit one end to the ink intake and another side with a syringe. Always squeeze. Remember, do not squeeze too hard. It's like half the force as you squeeze a lemon to make lemonade but twice as hard as an old lady squeezes a peach. That's where I put it. You're going to feel the print has opened up, and then you can inject consistently with the cleaning solution. You can see it is nice to break through that. Unclog it. Now you can gradually push the cleaning solution inside.

The first cleaning is horrible. That is expected. Then do another cleaning.

Perfect. Let me show you how to deal with warning messages. You may get this warning message that the ink is low, and you try to reset the chips on the cartridge, and nothing happens. The reason is your cartridge is auto-reset, so there's no way you can reset it manually. So what we're going to do is ignore those warnings. Just click okay, yes and keep using the printer and print more pages and ignore all those messages. They are just trying to get you into the store and buy actual Epson cartridges. Just say okay, and nothing will happen.

You keep printing until one day this happens. It says, "Cannot recognize the following ink cartridge." This is great because the magenta cartridge has been reset, and the printer cannot figure it out. How can you get a new cartridge, but you didn't open the printer lid? That's fooled the printer. Go for that, click and proceed. Then, open the printer door. Now what going to do is do exactly what the printer says.

We took the magenta out. No matter how much ink is in the cartridge, we're going to fill it up to the top and plug the refill hole, keep the air hole open, then press it down until we see the magenta icon light up. Then we do a check, and it says good. Close the scanner unit. 99% of the time, we should do whatever Epson asked us to do. Remember the happy screen? You have not installed genuine Epson ink cartridges. Magenta. Perfect. What will we do? Proceed. Now, Chris, what we're going to do with this screen. Yes. If you see, the ink level is full. Okay, let us do a heat transfer to show you the true color, so you don't have to look at this ugly black anymore. We print off a page on the transfer paper.

What you do is print on transfer paper, and you can press it. Press, this hot press can press it on any polyester directly, or you can press on treated cotton. If you have cotton, you have to have a type of treatment. Also, you can press on coated ceramics. Vinyl, you can do it directly. You have to figure out how you're going to treat the material. We're going to print on a piece of T-shirt, which made from polyester, T-shirts.

When the ink is heated, it has a face transfer. It transferred to an interface, and now it shows the actual color. Now you see black is black, yellow is yellow, and of course, you need to write everything in reverse.
