Initially there was a paper jam from the paper tray 2 which is the drawer that slides into the bottom of the printer. I pulled out the paper and it jammed again. The paper does not jam when fed through the foldout tray 1, which is the combination envelope and paper feeder. When the printer is powered up now, the display says, "Checking Printer," and blank paper starts coming out. I believe this is a test that the printer makes to ensure the jam is cleared up. However after four sheets of paper go through, the display shows "Paper jam" again and it stops in mid cycle. Sometimes the paper is not jammed but the display says it is anyway. The other malfunction is that the pickup rollers for tray 2 are activated even if there is no paper in the drawer. I found what was supposed to be the best solution hereand here The fixes made sense to me but it still is trying to pick up paper when it isn't supposed to. I dismantled a good portion of the printer checking for anything that might be causing it to jam but could not find any problem. I tried this fix as well with no success.
Thanks for your reply.
