 Hey guys, it's Kevin. Today we're trying to answer the question First thing to do is make sure that there's actually no paper When you have a fight with the paper jam, you might tore some part of paper and that may be still in it Oh, there's some debris also when you print the labels is pretty common that a piece of label just fall off and Oil stick inside the printer and you want to eliminate that possibility too so shut the printer off and get a flashlight and check everything inside and Remove the paper tray and turn the printer upside down and Start checking underneath too. There are tons of tutorials Some of them made by HP some made by other people to go through the process So I'm not going to cover it in detail here if their tutorial not working and you're desperate you can try this hold the printer upside down and Make sure your hand covered a scanner not like me. I forgot to cover it But you can see the piece of debris come out and just keep shaking it Okay, hold it like this, but the debris is already gone. So if the printer is too heavy, you can use your legs I'm sure HP will have a more elegant way of doing this So if you already did a dance, it might not be the foreign object It may be the sensors. Luckily, there are not lots of sensors in HP There are two in the back That is since the paper feeding In the front, we have a door sensor and we also have a Sensor measuring the position of the printer So let's say we have a piece of paper here and The Printed kind of move to the left. So that's considered paper jam The position of the print that is measured by this a piece of clear tape There are little tiny marks on the tape. So the printer can sense it and Decide where the position is So if the tape is dirty and the print head think it cannot move to the left paper jam There's no sensor between here and here. So your attention should be paid to Removing and discovering the foreign objects around this region Now we're gonna move on to the two sensors in the back The first sensor is a tree sensor. It's very hard to find it on the left and just Pull out and insert your paper tree and pay attention. You're gonna see it The paper tree will push this lever inside and Then mechanically the force transfer to the left and a small lever will go outside So you're gonna check if you push the tree in That's the lever go forward in out In out Looks good You may ask why we checked the tree sensor, but if you read it Our message clearly it says make sure the paper trees install properly and I did see and that This lever malfunction trigger exactly the same error message and you thought is a paper jam But actually spotted tree this lever assembly is totally over engineered and You can see there are lots of moving pieces and just a little if pieces out of position just a little bit and that lever will not go all the way forward and The lever is mounted on this piece of electronic board There are two slots one slot is for the tree another slot is for the paper ejection. We're gonna cover next See if the tree tree lever moving forward It'll move out of the slot. So I'll unblock the sensor and If it's not going forward completely 90 degrees that will still blocking the sensor That's the one of the area you may have Of course, you may have a malfunction board. So if you check out everything physically, it's fine It probably is the board The second sensor is the paper ejection sensor that's controlled by this lever in the middle You can say if there's a piece of paper the lever going to raise raise up by the one paper scone. It'll snap right back Let's check this printer does has the problem and that's in good position and Resup come down Resup. Oh, it doesn't come down sometime HP doesn't like people to mess our mess with their printers So if you want to keep this printer in a long run that you need to invest in a pair of School driver bits go to your local hardware store and Ask for a T10 and T6 Just like this or you can just go to bchtechnology.com and you can print this page and bring to the print print to your local store Use your T10 remove eight screws from the front This scanner hinge, there's no trick to it and just a brute force push it to the front and they'll snap off Now remove four screws along the back border Now you can loosen up the cover Lift the left panel straight up It'll come off and this connect is a big cable. Remember the blue side up and Now disconnect this little one blue side front Now you can remove the hole from panel I removed the duplex cover See that black lever Press the black lever to the left and now you can remove the roller All we've done is trying to gain access to the paper eject lever Now the only thing stop us is this piece of metal on the top Still using T10 to remove the four screws and now we're ready HP is so nice is designed this little thing You can just hold down to it and pull it straight up and the cover will be right off We'll install just a press straight down and until you hear a click if you need a replacement parts You can go to bch Technologies comm and go to printer parts HP and Pimper handling Here the two little springs that we're gonna talk about later and here is the electronic board and The PE sensor is inside that this whole thing or we just put them together It has a PE sensor everything so you don't need a Reconfigure it if you only need a PE sensor, we might have a listed sometime if we have we have in stock, but right now as this thing has the PE sensor has the paper crate sensor and the Electronic board so everything can be installed in one piece With the cover gone the lever can be pulled out I'm gonna show you a good one first and then we compare the bad one So the lever sits in the printer like this and Go up and down and the tension is Done by that little spring So the spring gonna load unload for each page and so that's a lot of times and may have a mental fatigue So the good ones on the left and the better ones on the right you can see it on the right it doesn't have that little hook that piece of hook broke off and That's why sometimes it can catch the lever and The lever can come down but sometimes it can't So that's why sometimes get a paper jam. Sometimes you don't have a paper jam And so without buying from BCH, you may find something like a glue glue it or have plier and rewire it Now let's assume the problem is not a PE sensor and we do have to access electronic board and or the tree sensor This connect the big and small cables of scanner and leave the scanner straight up and the scanner will come off flip over the printer and You're gonna see a tiny spring on each side Remember the two tiny springs I show you on the BCH website and this is it. It's kind of weird shape So remove those two Those two springs are holding this white piece of plastic Without the springs you can just snap the cover right off and Again when you install to the opposite just snap it back Now make sure you watch the whole video Don't do anything yet. Watch the whole video for how to disconnect this part Flip your printer upside-down and you're gonna see the middle. There's a black part stick out like this Okay, the ground plan is just a bend it like this and snap it off and that the whole unit can be removed and put it back and Then we'll print happily ever after However, if you don't know how to snap it you're gonna break this and this part will be look like this instead of look like this Let me remove the bottom of the printer I show you so this thing is stands stays here the axle That this thing is turning is a stability stabilized on the whole black plate Okay, see here. Okay, and Then here's comes to the little box is need to grab It's grabbing with a hook in the back So now have an axle and now I'm grabbing this little box When we wrote it forward if we use a even force they think will not break and It's easily grab and grab The only time you can break it is you apply an uneven force Because the whole blackboard is loose. So your axle may not be Straight so you might twist a little bit then when you pull is kind of a twisted and the one side that got More force than the other one How about that snap it off like a boss You can do it all day long To install it just upset and the slide it in in the axle first Then bend it backwards Here I removed the bottom so there's nothing to stop the little box moving back by in reality. There's Bottom to stop the box from moving back So the box was sliding easily now you can take the whole board out by disconnecting the cable and you can access to the tree sensor and you can Take the electronic board if you need to replace it or just swap in a new one the installation is just reverse what we did and I already covered a couple of things I want to emphasize when doing the installation I hope you enjoyed this video. I hope this fix your problem and visit us at www.bchtechnologies.com or locally at Greensboro, North Carolina. Cheers
