HP LaserJet 2430 - Paper Jam in Tray 3

hi EE folks

i have no idea why my HP LaserJet 2430dtn recently always has paper jam in tray 3. the printer prints well using other trays, it seems the issue only happens in the tray 3, and the situation would look like shown in below picture once i open the tray 3 after jam.

Probably pickup rollers.

These are the wheel or semicircle rubber clad bits of plastic that pick the paper up and feed it.  They tend to wear and get dirty after a while. They can be cleaned with alcohol, or replaced pretty easily.

Here is a video showing replacement.

Here are rollers, for $8.99 from Amazon.

thanks for your comment and suggestion.

i am just wondering how to determine it is caused by pickup rollers. just to simply check if they are dirty?

Probably just try cleaning them with a rag and alcohol to start with. They get coated with dust and oil and crap after a while.  If the printer has done a lot of work they may need replacement.

At $8.99 it is usually easier to just swap them.

as shown below, it seems the rollers themselves are not that dirty, and i did clean them using alcohol swab. do i also need to clean the surrounding parts and surface?
Inside Tray 3thanks again.

Normally, just cleaning the rollers is enough.  However, they do get worn over time as well, so the replacement is pretty common, and that printer is quite an old model I believe.  Our maintenance engineers change them pretty much by default.

the aged printer started working again after cleaning the rollers and surrounding parts as instructed.

also placed an felt pad under the Tray 3 to make its support feet on the same horizontal level. probably, it was also another reason caused the problem.

thanks heaps for your help.
