 Hey guys, this is Kevin. I still ask Kevin project, which I pick up a couple of our subscribers questions and I try to answer them. Again, doesn't guarantee is correct answer and doesn't guarantee is good answer. So our friend bought a A3DTGA printer. This printer is based on Epson short color P400 which is really popular model. And of course it has a DX7 printer. And I see the first problem immediately is your bought from China is probably Aliexpress. So when the printer arrives, only print 5 t-shirts and the printer give air and try to contact the supplier. Unfortunately, they are not supportive and not answering any questions. And I try to replace the motherboard and the print net but still the air is still there. Just show you some truth about Aliexpress. You can see I buy hundreds of items from Aliexpress every year and it seems really easy to dispute if something wrong with the order. So you just go to Aliexpress and find your order view detail and here you can just click open dispute and you can select refund only or return goods. However, other than you did not receive it which is highly unlikely because they give you a tracking. If something anything is wrong, there is no way you can get your money back. So for example, I open a dispute with the printers I bought. Immediately Aliexpress rejected my dispute and said the video is needed. Actually before this, I already shoot pictures of the nozzle check and describe what I did and I spent half an hour right up next paragraph and telling them that I had experienced with the printer and basically you send me a malfunction print net. So I asked for video so I spent another hour to make a detailed video and show them what's wrong. And I was really happy that they send me an email saying hey your dispute is resolved. That's how much money I got. And here you can see the final resolution refund is zero. And you and the seller do not return agreement. Of course the seller is gone. And here's my history. So refunds zero. Okay, big zero. And here's another story from my Facebook group. Somebody bought a printer and I left damaged. Contact the seller. The seller said yeah, send it back. And the shipping was $1,000. And this one she tried to argue with the payment system. However, if you use credit card or any kind of American payment, the deal is you have to spend your money send it back before they can reimburse you. So you can screw it either way. Therefore guys just stay with Amazon, eBay, Walmart, Target. It just breaks my heart every time somebody told me this is everything I have. Could you fix this printer? So I'll give you my best shot. However, for the audience over there, if you have a better idea or like something you want to mention, please, please put down the comments. And I can forward it to the person who asked the question. Okay, I'll show the video in one take. Then we don't dissect it into segments. Hi, Kevin. Thanks so much for your positive response on the email. So this is the printer. When I checked on the print head here, it's locked on the home position. And when I switch it on, I want you to observe with me. So here we go. This is the error that it's giving. This is the error. And if I try to check now on the print head, it's not locked anymore. And let me come here and check on the on the episode program. And I will say check errors. So it says error code 52 H. That's the error it brings. I would really appreciate if this printer can work and come back to life. And if I switch it off again, switch it off, then the print head like that on. So you can see the movement. The head is moving. The error continues. So the error continues. The print head is not locked. So let's see. The print head is in the docking station and locked. That's good. So right now we're power off. So that's a good thing. Then we turn the power on. And the power is good. Next thing you're going to see is if the print head move to both directions, which it reads the timing scale, which is a clear belt on the printer. So it seems it moves smoothly and it didn't slam on either side. So I assume that's okay. Let's see it in another way. So basically we have the carriage that gets locked with the red clock. And we have a clear belt. The carriage has a reader. So the reader is positioned. The position will be from 0 to 18. I think in your case it was from 0 to 120. I think it doesn't matter. If it cannot read a belt, you're going to see it get just slammed back and forth. So that's what we haven't seen. So the belt is okay and the reader is okay. And we know it released the lock at some point of time. Basically before that, a check if your with ink is overflow or not. So your with ink counter is okay. If you need any of the diagram that I'm going to show you, just text word absent start and the number one absent start one to this number. And I'll text you back with a link. Printer released the lock. And we're going to hear the page feed pf motor rotate clockwise. It sounds like it's trying to feed a page. Here's the pf motor. That sounds good. And with the lock off, it's trying to move to the left first. Trying to move the right first, then move to the left. And here I just move the right and then stay at the home position. And then it started initialization, the page feed initialization process. So if you page feed the motor or something wrong with it, you're going to hear, you're going to stop right here. So we just just rotating with the carriage in the home position or sort of in the middle. It's just rotating this page feed motor. And after that, I move to the left and just start doing things crazy. What it does is I check the couple of sensors. One thing is, one is the low temperature operating sequence and the pf measurement, page feed measurement and pw sensor. pw sensor. pw sensor is mounted underneath the printer carriage. And pf is the page feed measurement. That's when you rotate it. It reads the how the paper feeds. And I think your problem is right here. After go to the ch-ch-ch-ch and you get air here. So if that one is finished, you're going to go to the last step, which you didn't see the last step is the printer stop here and then move to the right. You lock and then move back and stay here. Okay. So that's number eight. You didn't see. You'll stop at about right here. Because I stopped here and the printer is not locked, you didn't go to number eight to lock it. So that's why the thing is unlocked. And now let's check at the printer's airlock. Number 52 is paper jam. And air 71 is L52H is the paper jam for an object deformation of the mainframe. Okay. That doesn't give us too much because you don't have a paper there. You don't have a paper jam. And so before that is 72H, 71H is the page feed APG unit failure, either APG sensor failure or the motor failure. Basically, your printer cannot measure the page feed speed. So I assume there's a piece of paper there caused a paper jam and it aired out. In your second part of video that you show is kind of weird. When you start up again, the printer goes slowly, very slowly to the left. And this is because if you had a paper jam air before, the printer going to go to a different set of routine, it will slowly move to the left, very, very slowly. So in case you really have a paper jam, it's going to run into the paper. Because you use a DTG printer, your page feed is different from regular printer. So I'll suggest you to check the connections of the page feed sensor and also check the motor. Just make sure that all the cables are secured. Again, if you open the link that I shared with you on your cell phone, you're going to see the old reference diagram that I used. On the bottom, I also searched for some solutions on Google. And the first one I can find is 51H on the DTG printer. And 51H, you can see there is the same thing as 52H is the paper jam or form object. If you click on the link, you'll see it has problems and okay, fixed. That's because one of the pins to the connector is loose. So put the pin back and problem fixed. And for the 71H, it's even closer to your problem. So basically it's identified as the APG sensor or motor. And when the guy looked at it, the sensor is out of place. So he popped it back in and everything works. And he gave you really good pictures and which you can blow up and take a closer look. Okay, I hope this will fix your problem.
