HP 4V keeps jamming on start of feed, which parts to replace?

[John]

After several years of great service, my LaserJet 4V is now constantly
jamming as soon as the paper starts moving, from both the MP tray and
the paper cassette.

I tried checking on the web to see which parts I need to replace (for
both MP tray and cassette feeding) but am very confused. It seems
that I need to replace several pickup rollers (Lower Cassette and MP
tray) and the Separation Pad to do the job?

The print quality is still great but it's time to grab the tools and
replace some parts. This jamming is driving me crazy.

Is there a web site you can recommend for a list of parts I might need
and, perhaps, instructions to do the job? I'd be happy to do the leg
work, I just need to sort out what these vendors say I might need and
what I actually do need.

Thanks!

You can buy Rubber Rejuventor at electronic supply houses that will
probably give you a few more years of service.

I was thinking about that but the MP roller seems really grippy, not
shiny. Might be worth a try though...going crazy.
