 Welcome to BCH Technologies. This is Kevin. Today we're going to troubleshoot the problem that cartridge cannot be recognized. This is different than you press the OK and then you press the white button. And if after that is still not recognized, then you're going to watch this video. So what happened is, during the shipment, you may have this thing get knocked out of the balance. So it doesn't have a good contact with the printer. So we're going to hit OK to move this to the center. Remember the white reset button only works if this is in the center. So that's why you need to hit OK first. You can see this board is kind of leaning this way now, so that probably is the reason. So what I do is I use my finger, just put this back. Now I use my finger to squeeze the G board and make sure it has a good contact with the assembly. This is how the electronic board gets assembled on the back of the board. So if this one is out, it may influence the other contact points. So this feels good. And then I want to check G boards. They are down. The absence G board is removable. So sometimes it pops up like this. So if you see from the top, you're going to see it pops up. So you can just use your finger or something to push it down. And let me pop another one. You can see it didn't completely pop up, but it's already offline. So you can just push it down. So for here, because we have a problem with the magenta, I'm going to use a pin. Oh, it actually says up. So I'm just pushing it to make sure they're all down in the outs. Where the problem is? OK, problem fixed. OK, let me show you what if the chipboard is completely bad. So you have to replace the whole chipboard. So we go to setup. And maintenance and in cartridge replacement. And click start. So now this is going to move to the middle. So I use my finger, pull this back. I may need to remove a little bit. Some of this to get the chipboard. OK, make sure all the tubes are not twisted. OK, now get a new one. So what you want is the first thing is you go straight in. Like this. And then you clip. And now to a final check of those pins. I hope you enjoyed this video.
