Another one is straightforward to get ink in, and you won't damage the printer if you use the wrong hole. The two holes are connected, and if you find one hole is tough to get ink in, you're refilling the wrong hole. We use something to poke it in and remove it. Then there's a refill hole in the middle, concealed by a clear plug. You unplug this hole and never plug it back.
We're going to install a new set of cartridges, a refillable cartridge, and the CIS. The tank is divided into different chambers, and I think it is more stable than column one. That column regulates the ink pressure, and I'm more favorable for a split ink design. You can see there's a big column in the middle. This is a four-piece plastic refill needle. The adapter can be found at the BCH website and called accessories and syringes and needles. 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. If you notice, we already have the tanks open, and we installed air filters on the ink tank. We took a syringe, and then we removed the top plug from the cartridge and then drew ink from the tank. There wasn't any ink inside any of the cartridges. We took the CIS out and checked the ink in the cartridges. Let's do a blank page after four cleanings. We'll use the printer's built-in function to clean it twice. All nozzles are blank, a piece of blank paper. Let's check on the nozzles and see if there are any clogged nozzles. Okay, it looks like our first problem was solved. "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. The second screen is like a divorce paper. Are you trying to save some money, naughty boy?" If you read it carefully, it says, "You are not installed genuine Epson cartridges. When we see this screen, we know Epson is accepting the new cartridge. It looks scary, but I call it a happy screen. After closing the lid, Epson displays this screen. We'll push the check button and make sure the cartridges are installed correctly. Once we release the button, they'll light up again. As the button is pressed, the corresponding symbol on the LED screen is grayed out. The reset button will discontinue the electronic currency on the chip temporarily and thus for the printer to think. Then, press and hold the reset button on the CIS. We'll wait until the cartridge comes to a stop. The correct way is to click the proceed button and then open the lid. Many people would open up the printer lid and start troubleshooting. The first problem is the printer complains about not recognizing all the cartridges. We'll cover troubleshooting CIS, installing, and priming refillable cartridges, as well as diagnosis and unclogging printheads. Today we're going to troubleshoot an Epson WF-7610, equipped with a continuous ink supply system.
