This can be caused by a sensor (if he is mechanic) displaced the movable mechanism of the same and when it passes the leaf is joined, (if is optical, can be dirty the surface towards where it points the sensor, if he is not this, then the sensor is defective.
It disassembles the parts of exit, and verifies that the sensors are in good state and clean.

Its a misfeed in the fusing section. The paper didn't get to the exit sensor after the registration roller by the drum was activated. Check the fuser and drum areas. It can be caused by a dirty exit sensor, registration rollers not having pressure, a bad fuser roller or drive gear, or the exit rollers not making good contact.

I replaced one exit sensor i found faulty and the problem disappeared.

Verify the exit sensor actuator and the entrance sensor actuator.

If you are a technical person you may want to remove the tray from the machine (pull all the way out, tilt upwards, and pull.) to clean the rollers. Once the trays are removed you will see a set of three rollers for each tray. They can be removed and cleaned or cleaned directly on the machine. They may have build up dust on them preventing feed. Reinstall the trays the same way they came out but in reverse steps.

Then:

1. Pull offending tray all the way out and remove paper.
2. Unlock the side guides and make sure they move freely
3. Set about 100 sheets of NEW paper for now and adjust the side guides and the end fence. The end fence must be against the paper (touching) and the side guides must NOT be too tight agains the paper as this will prevent the tray from lifting.
4. Make sure the paper size dial is set to the paper SIZE and ORIENTATION.
5. Close tray and test.

Let us know what happens. In the worst case it could be a Magnetic clutch malfunction
