paper jam error message - HP Officejet 8500 pro - please help, deployed no return option

Thanks for the response but I just purchased this product and shouldn't have to take time out of my busy day to do all of this.  HP should lubricate and fix the problem prior to selling the products to consumers. I will be returning it soon.  Thank you.

The refurb (replacing my brand new unused printer) arrived a little while ago and at least this one works.  I'm wondering if I should lube it as soon as I can get a fresh can of WD40.

Hopefully it will keep working properly and will last longer than a year.  Good luck.

TURBO1951 - Since HP is never going to do the right thing and stop using this inferior part we should tell stores to stop carrying HP printers. Until then I am glad that we are able to use this forum. Spraying the white gear with WD40 and Gunk helped me for a while, but it did not stop the problem from reocurring. So, I need a longer term solution to FIX & REPLACE the gear before it breaks. Please advise.

In the meantime I guess that once or twice a year I should just apply a few drops of wd40 or the like to the white and black gears (teeth and shaft where reachable) and to that thing on a shaft with a spring.  I think the assumption by HP and other manufacturers is that 'nylon' gears are 'self' lubricating by their nature and don't need oil, but far too often they stick anyway.l

I open the hood once per month and spray wd 40 on anything that moves. I also work the rod with the spring around it, back and forth to make sure it is well lubricated. I dont know why HP doesnt solve this problem somehow? It probably would cost too much and put a dent in their profits. I was ready to take a sledge hammer to mine until I found the fix in the blog. Thank God for creative do it yourselfers.

I'm convinced that the drive to make things as cheaply as possible and the mistaken notion that nylon and plastic gears and sleeves are 'self lubricating' has led to many designs that wear out long before they should.

You guys are great!! I had my HP 8500 in the car and ready to head out to trade it in for anything but another HP Printer. I found this forum and tried lubricating the gears. It worked!! Just saved me $500.00.  BTW WD40 is not a good lubricant, it's a good cleaner. I used Liquid Wrench spray. Thanks again.

Like everyone else on this issue, I’ve been getting the same problems as well.  I’ve been looking through all on this forum to see what others have done and none of it seems to be working.  I’ve even chatted with HP but that was no help.

I’ve gone through what M_ANHalt mentioned with the….

…On the left side of the printer under the dual ink packs there is a BLACK roller with a white cylinder gear inside it. I watched the printer try to reset it self about 10 times before I realized that the white inner gear was hanging up on the black outer gear.

And also what JLWojo has mentioned on the ….

I then saw the black gear (near the top of even with the bar with all the little rubber rollers on it) and white gear below it a little to the left (1/8 inch) (as indicated in prior post).

Using my finger, I manually rolled the gears (sometimes black sometime white)

And none of it seems to be working.  I’ve added a lot of WD40 which working with the gears inside the machine.  I did see a piece that I wasn’t sure broke off or doesn’t really have any concern with the “fake paper jam”?

The detached piece below, is this normal?

Or does this piece need to be attached?
