HP Officejet J6400 hinge Broken

Or you can take it apart like I did, see the attached photos and use JB weld but be very careful. I put paper between the moving parts to not put JB weld over every thing. I also practice placing the hinge with a pair of needle nose pliers. To try and get a good feel about this. You will want to scrap off the excess with a small flat head screw driver, on the inside and outsides of the plastic tabs. Let it dry for 24 hours. You will need to cut a piece of the while plastic out to be able to slide the metal hinge pin back into place, I would do this first but I did not think far enough in advanced that way you can slid the pin in to let is dry and the two ends will be in perfect alignment. Ideally you would want to replace the hing but I could not figure how to get the front right white lower cover off to get to the one screw that is holding on the black top piece to be able to figure out how to remove the hing assembly completely and go to a local printer repair shop and get the new hinge if HP still sells the part and it is not $100.

I took the photos with my 4S so I am not going to re-size them to 200K because you wont be able to see anything.

Hope this helps.

The hinges on the cartridge access door broke and I can't figure out how they worked before they broke as I would like to just set the top back down and have it mesh so it lays flat and the open door...

When this happened to my Officejet 6400, I noticed that by putting weight on the hinge area, the printer would work. I have made a makeshift clip out of wire hanger so that there is enough pressure on the hinge side of the printer to keep the printer working. You may have to take the clips off to change the cartridge but we can re set the clips. Good luck !! Jyotiprakash

The cover or whatever you call it on my HP Officejet J6400; the hinge on the left side accidentally came off and we're unable to reattach the cover or hood to the main body. Because of this, the ink...

If there is someone who is quite confident and with the help of a service guide (which can be download from internet) then yes it can be done, but do not attempt repair if you are not certain, i would leave it to a skilled repair/service centre.

The hinge on the cover cracked. Can this be replaced?

I used an offset cabinet hinge & screwed it into the body of the printer, & the cover. The offset has to be jiggled a bit to open, but works fine on closing.
Otherwise, HP wants you to buy a complete new scanner cover.

Hinges for top cover for HP officejet 6210- Q5820A

Let me know if you find a source for replacements. In the mean time, I kept my unit working by just removing the broken top half of the hinge.
You have to remove 5 screws using a TORX T10 screwdriver. First remove the small plate covering the back of hinge on the outside. Then remove the two vertical screws at the top of the hinge up under the hinge lip. Then open the cover (be careful to hold it in place so as not to damage the three flex connections between the lid and body) and remove the other two screws at the top of the hinge. Remove the broken top half of the hinge and lower the cover back down. Until you find a replacement hinge, you can put a piece of heavy duty tape on the back where the hinge was.

Broken hinge

Take the scanner lid off by squeezing the plastic hinges inserted into the back of the cabinet.
Take the top hinge of the cartridge door off with the 2 tork screws holding it, using a small screw driver.
Go to a hardware store & pick up a pair of cabinet hinges no more than 2". (You need to buy a pair because they do not come separate)
Place the new cabinet hinge on the back to the right of the bottom hinge of the base cabinet. Mark holes, drill one top, in the door, & 1 bottom cabinet, pilot holes. Check alignment & insert screws.
Tighten the bottom screws. Leave a little slack in the top screws as they have to be a little off set to close completely. You will only need to open this Cartridge door to change cartriges, so, no sweat.
My cost was under $5 for a pair of brass hinges, & my time, about an hour, taking my time.
It's too bad HP won't supply their offset hinges. They are inexpensive & easy to replace.
I've had my unit for exactly 4 years now, so this fix is a lot cheaper than buying a new one. Besides, I have ink already purchased that does not fit new printers.....go figure....
