Good day

I hope im on the right form as i am a new user

i have an Olivetti PGL2150 that is giving me a headache , firstly i went out for the machine not printing correctly i.e the heading of the letter head starts printing in the middle of the page , i have replaced all the clutches and feed rollers and made no difference at all , i then took out the registration clutch again to try another one and after replacing the reg clutch i now have blank prints , i have tries reversing the process and still no luck , still sitting with blank prints

any suggestions and assistance will be appreciated
