I have Jam9110 or J9001 on Document Feeder. Its on Taskalfa 2551ci, and DF is DF-773.
i changed two clutch and actuator because they were defective. I still didn't get the solution. The Jam still appears just after the white plastic sensor, when the DF is raised. So, it passes the white plastic and stops at the entrance to the output section of the Document Feeder. I did the service three times on this machine, and I saw that the paper-pulling erasers, as they pull the paper where Jam appears, the pulleys should rotate in the other direction. Will I solve the problem if I replace the Servo motor? Thank you in advance.
