Canon MF6530: Persistent paper jam. Took video in the tray. No error code

The display says Paper Jam / Open Left Cover without any code. I don't think the jam is real. I put a camera inside the paper tray and took a video . In the video, I see the following things. At 0:03, the cassette pickup roller (CPR) would push the top paper forward. At 0:04, the CPR would push that top paper once more. After that, the top paper completely goes in. At 0:06, the CPR would push the 2nd paper. Then the printer says it gets a paper jam. The top of the 2nd piece of paper is right at the end of the registration roller. The paper doesn't go a bit beyond the registration roller. After
