Odd to say I remember it because it is the opposite of the typewriter I used.
Well if it was normal I had no need to remember it... :-)
In the typewriter when you finish to digit the line you use the carriage return lever, that before makes roll the drum, the newline, and after allow you to manually operate the carriage return.
You can listen from this record from freesound.org the sound of the paper feeding in the beginning, and at around -1:03 seconds from the end, after the bell warning for the end of the line sound of the drum that rolls and after the one of the carriage return.
