HP 4600 LJ have a problem with one of the cogs on the left hand side.

Hi Guys

I'm trying to find out what is causing the squeaking noise coming from the left hand side of the printer. I have greased all components I can find and it seems to come back once the printer gets hot.

I think the component is at the very bottom one that drivs the shaft up and down that drives the big Plastic cogs for the Drums..

Also does anyone know what manuals are out there for this beast? I need to see if there a parts manual as all I have found so far is a service manual which is pretty useless for this kind of event:S

Any help would be appreciated:D

Flip thru the Service Manual until you get to page 451. That's chapter 8
"Parts and Diagrams".

Are you sure that it's not the ETB or one of the cartridges that's squeaking?
Go to page 402 and run the Diags. I believe that you can run tests on the various motors. That might help.
