Laserjet Pro 200 Jam in tray 1 on second page

[ribico]

Hi, I've had the Laserjet Pro 200 color M251nw for 10 or so years, regular but low volume usage. It recently developed the Jam in tray 1 error. This always happens on the 2nd page of multi-page job (first page and all single page demo and test pages print fine).  After extensive googling of this condition I purchased a maintenance kit consisting of replacement pick, separation and transfer rollers and fuser assembly.  All have been installed.  Newest Windows 10 drivers and printer firmware have been applied. After all that still getting the same cursed error.  That second page may not make it past the rollers, or may get stuck halfway through the fuser.  Any thoughts on what I should do now? (please don't suggest the curb, I do like the print quality this printer produces and the newer similar replacement models are hard to find in stock anywhere).  Thank you all.

That sounds like a bad sensor in the paper path. The printer does not detect that the paper has passed a certain point and stops printing to prevent damage. This can be tricky to track down, especially with the limited feedback the printer provides in cases of jams.
