Then today i did an attempt to solve the problem without changing anything:
-performed a forced toner k supply sp 2-251-1
-performed sp 5-804-99 (dev k motor rotation) for about 15 minutes
-set sp 1-010-5 , sp 1-011-5 and sp 1-o12-5 from 0 to 3 (dev k motor speed)
It seems working good now (i don't know for how long!!)
I let you know the long term result.
