13.1.50 Jam in HP4050

I have a HP4050 just about exactly a year old, 52,000 page count. Yesterday it started making a groaning sound and showing the 13.1.50 paper feed 1, paper late jam error on the Event Log.

It'll jam 90\% of the time from the main tray with this error, but prints fine with no noise from tray 1 (the small upper drop down tray). Though it's reporting a paper jam, the paper doesn't seem to have moved at all from the main, bottom tray when it errors.

Looking at the rubber pickup parts, they seem good as new (and this isn't an old printer). Is it still likely that the pickup kit recomended in the troubleshooting section here is the fix?

Something else to look for?

Wacky. I now have a HP 4000 in the same area that's reported as doing the same thing, and the error log shows the same 13.1.50 error, though this one has a higher page count: 99,000.

Someone already pulled down the Tray 1 and put paper in there to keep it going. As with the 4050, it works fine from the upper tray.

You can't always go by the look of the rollers. The rollers are supposed to go 200K, but I've found that to not always be true. The groaning sound is a classic symptom of bad pickup rollers.

Bad torque limiter.

After much debate and trials, I've found (so far no call backs!), that if you replace the feed/sep rollers, separation roller clutch and the separation roller tension spring (re-install in 2nd notch)...problem will be resolved.
