[Jamming] Konica 7155 without reverse funktion and jam 32-2 or 32-3

[Laserbeam]

Hi all,

today I had this problem on a 7155. During normal 1 sided copy (with the face down) I always get a jam-code 32-2 or 32-3. The reverse is dysfunctional and the paper runs without stopping through the hole ADU-reverse unit and falls to the bottom of the machine. (See my attachment).
Copy mode with face up in the upper tray works fine.

I replaced the fixing-unit, ADU-board and the ADU-reverse actuator but unfortunately without success.

in his 2nd picture...your looking for a spring that returns an actuator thru a photo sensor.....make sure it has enough tension, or it will not return in time. Chased my tail on this same thing!!!

Also make sure the the sensor is in proper position and actuator isn't broken.
