 Here you guys come here, OfficeJet, the printhead cannot move, sounds familiar? Let me take this one as an example, I already took the printhead out, so you can see clearly. This piece has nothing to do with it. The problem is this little sucker, the waste tank sucker in the middle. You can see when I move the carriage, it's moved all together, that's because its position is too high, so it locks itself with the carriage. The sucker is driven by this gear. It's easier to turn from the left side, so let me turn this counterclockwise. Oh, it's easier because the wheel is bigger. You can see nothing happened. The trick is on this little lever right here. So if I push the lever to the right, you can see there's a little gear underneath, moving to the left. Now I'm holding this lever and turn the gear again. Counterclockwise going in, and clockwise going out. We are not using the printer, it goes all the way out and reads the platform and seals the printhead. We call it a cap position. We are using the printer and it should go backwards and lower the platform. So let's control this lever. The lever is controlled by the printhead carriage. So if I want to lower the platform, I need to move the carriage to the right. So what if the printer is out of sync? The platform is raised and they try to move to the left. Welcome to wonderful HP design. Okay, let's do HP's job and fix this. I'm going to put a previous video on how to take the cover off if you want to do the cover. Anyway, so just push the carriage to the right and start turning the big wheels. Or if you have a small hand, turn the small wheels, either way, that's fine. And you can see the platform is lowered and it's moving all the way back. Although HP engineer is not good at designing things and they're successful make this part really ugly and really gross. And I really enjoy watching it every time we track all the way back. Okay, now it's fixed. I hope this video saved you some mule.
