I have spent quite abit of time searching how to solve this problem.
When a print job is sent or even when the machine is trying to do a paper jam, cleaning job, the printer displays the error: "Paper Jam - open front door A to clear". I proceed to open the door A, checked for any debris. Then I get the error "Paper jam - Remove Tray 2 to clear". After that, I remove the tray, check the paper and readjust the length and width paper edge guides accordingly.
Then it shows the error "Paper Jam - open front door A to clear" again.
Error Code in all of the error displays: 89,102 [R3M3]
