Color Laserjet 1600 false paper jam issue

[KDP250]

I had asked this question previously:

I've got a Color Laserjet 1600 that had worked flawlessly until a couple months ago.  I started getting the "paper jam in tray 2" message every single time I tried to print anything.  I'd tear the printer apart and there's no paper jam at any time.  I can still feed paper a sheet at a time via the front of the printer, but that's defeating the purpose of me having a printer when it comes to printing multiple pages.  Simply opening the front door clears the paper jam issue after it reboots, but as soon as it tries to print again that same message pops up.  I'm not sure what happened as the printer has sat in the same place since I bought it a few years ago.  Has anyone else encountered this?  Is there something I need to clean or tighten up?  I'm at a loss.

East2100 had replied saying to check for a rubber pad at the front of the tray, which I didn't have and I replaced it.  It still gives me the paper jam error.  

I watched from the back of the printer as I tried to print and it tries to grab paper but doesn't actually grab it.  It makes 3 attempts then throws the error.

If anyone has seen this similar error, even with a different model, I'd love to hear how you fixed it.

Have you replaced the pickup roller in the tray yet? Your post is unclear. Based on the fact that the printer feeds fine from the manual tray suggests a problem in the pickup area and based on the age of your printer a worn or dirty roller is quite likely.
