HP LaserJet Pro M127fw paper feed jam caused problem

[Ent22]

My printer jammed paper coming from the stack.  HP help seems only to consider that jams would occur in the document feed, so I couldn't find any way to remove the torn paper behind the paper tray.  I opened it up as much as possible, and managed to get the torn paper out, but in the process I hand-rolled the square shaft at the paper pickup mechanism.  The small blue plastic part which has what looks like a wide thick rubber band popped off.  Has anyone any idea how to get it back on?  I'm not afraid to take the bottom of the printer off, if that would help, and if it's not just a complete snap-together assembly.

Not very impressed with HP, who say essentially "It's beyond warranty, go buy another."  If I have to, it will probably be another brand!

I am not familiar with the part that you describe.  The pick up assembly, RM2-5135-000CN, does not show this part or a belt.  The P/U roller shaft is driven by gears on the main drive.  I do not remember any belts used in the paper feeding process.  You will need to attach pictures of part and location it came from.  Or, you can remove pick up assembly and see if you can figure it out.  Repairing small office MFPs, regardless of manufacture, is a challenge.  The part that is broken may not be a part that is available.

The part that came off sits between the white spools on the shaft.  It is sitting just to the left of the spools, blue plastic with a grey soft plastic band around it.  That's what I'd called "like a rubber band".  This is all below the toner cartridge which has been taken out.  Thanks for your help.

The blue part with the gray rubber is your pick up roller, RL1-2593-000CN.  It has indentations on white part attached to shaft and on the blue part of the roller.  Just snaps in place.  Big roller indents usually install first on the bottom of white roller holder. Youtube will have a video.

Also, the white part on the roller shaft is out of position.  You will have to rotate the shaft to the correct position.  Google the pick up assembly part number.  Find the roller and look for two tabs at the top of roller.  When in the correct position, there are two tabs at the top of the white roller holder.  These tabs are used to release the roller from the holder.  Good luck.
