canon ir3300 bypass fails

[polo]

When i put paper in bypass tray, sensor detect this and if i tip enter button copier try to pull the paper but apears signal that jam in bypass. I have to open and close two trays and in this moment the process go on.
I think maybe the black lever is the problem ¿but what i can do to fix that?

what are the Jam codes ?? if any
check the flag of PS22 the multifeeder paper sensor
make sure the black plastic cam follower #13 on the right side of the lower door has not fallen off-will prevent the flag of PS22 the multifeeder paper sensor from reaching the sensor when the door was closed.
