I need to replace broken door hinges on hp J 5780 Officejet printer

SOURCE: 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.

I "inherited" a 6210xi because BOTH hinges were broken... poor and weak plastic design that breaks if the operator tries to raise the access past about 40 degrees for access to ink cartridges... of course after the hinges break it doesn't close properly to start again (except with creative taping!). In my pursuit of these parts I found that the lower hinge part (broken) Part#JB6100289A is actually a Samsung part for their SCX-15 printer/scanner. It was also interesting to find several of these 6210xi's for sale on eBay and other places for $10 or less as "broken, parts only" and AMAZINGLY, it was the same broken hinge part that put all of these out of service. Found the HP Part number as RG5-6317-0000N but couldn't find anything except to buy either the Top half of a whole 6210 or the Bottom half for hundreds of $$'s, far more than the WHOLE new working item would be. UED.net listed the part as "non-stocking" at $2.27 each, available Aug 8, 08, but it turned out to be that they are negotiating for access to that parts and VIOLA! a few months later I received SIX hinges at $2.27 each plus shipping. You have to be creative to keep your old stuff working.

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....
Aloha.
