Squeaking during printing from Tray 3

[Guest]

We have an HP LaserJet 600 M602 (CE993A) that makes a loud squeak while printing (feeding/picking up paper).
Through swapping Tray 2/3 and printing only from Tray 2 or Tray 3 I was able to isolate the sound to the lower, Tray 3, mechanism (not the paper tray itself).
It has been a while since I've tackled printers and was wondering if simply a well placed drop of oil would solve this issue, and where to place said drop of oil.
Thanks!

i have found those white idler rollers that are in the section where the paper goes from one tray up to the next, you can see them when you pull the paper drawer and look on the bottom where the black and white rollers bring the paper up from below, and also behind inside the tray 1 feed in section. those white idlers get dry and squeak. get some oil on the sides or if you can remove them and oil the shaft where they ride may resolve the issue. also, i usually put a drop of oil on the separation roller shaft when changing the rollers as that can do it also.
