You really should have someone look at that machine that knows what there doing.
The red headed screws are at either end of the drum unit to keep the dcb blade of the drum while in transport.

i have replace the the yellow blade 3 times same result the thing is like i said i can see this lines on print even before the drum show scratches...

are you putting dusting powder on the drum n blade when reassembling ? if not that could cause the scratches.
