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 upload the video to youtube:
In the video, I see the following things.
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 I open the left cover, I can't just pull that single piece of paper out. I have to manually roll the roller to get the 2nd paper out.
On page 111, the service manual talks about a "Retry Pickup":
At first, I thought maybe SR11 was faulty and couldn't detect the paper. That would make the machine do that "retry pickup".
But I am not sure because I can't even see an error code for the jam.
Does a jam always have an error code? If that is the case, how to see that code?
I have tried:
But that history is blank.
I also did several sensor tests using the normal sensor mode (not the latch mode).
Test of the cassette paper sensor (SR9):
When the tray has papers, CAS = 1. When the tray has no paper, CAS = 0.
What I see: 0/tray has no paper, 1/tray has paper.
But page 224 (F14-14) of the manual says the exact opposite: "CAS: Cassette paper sensor (SR9): 0/Document presence, 1/Document absent".
What I see: 0/no paper, 1/has paper.
The manual says the exact opposite: "REG: Registration sensor (SR11): 0/Document presence, 1/Document absent”
What I see: 0 0/no paper, 1 0/has paper.
The manual says the same thing: "Delivery sensor (SR5): 1/Document presence, 0/Document absence.”
