I have an 8570 that will not print from the first (primary/internal) tray, or 'tray 2' as it's designated. I keep getting a jam in door A and have to pull the sheet out. Oddly enough, the thing runs fine from the 3rd tray below and from the manual feed.
Troubleshooting tips would be appreciated.
Take out tray 2 and clean the rollers that feed the paper
I don't think the problem is with the tray, I suspect the problem is in the printer, behind door A. See attached photo. I have swapped out trays, and if the problem was with the rollers, the problem would follow from tray 2 to tray 3.
Then you will need to call for service, or dig up a service manual and figure out what part is at fault, could be something blocking the path.
