Hi Mr.Robert Backhaus,
Thanks a million..for saving my printer.
I've contacted HP and they asked me to dispose of the printer as there is no service available for consumer printers.
I've not go the skill to go all out following your useful and detailed step by step guide..
What I did was I tried to move the lever you highlighted...it was jammed at first...then it snapped...I guess the spring broke...
Then I use a rubber band to hook it to the metal panel...to simulate the return spring function..
And it works.
Not a proper repair...
Just a Band It type of get it running solution.
Thank you so much for your generous sharing.
Else my OfficeJet Pro 8620 will never be able to function again because of a spring.
