I think your printer must be a fake. The video contained no sound of the annoyingly loud paper advance mechanism. :-)

That is the fun of incremental drive, the printer in the 9825/35 is about the loudest I have ever heard, but before stepper motors became really common, incremental drive (nicknamed "incredible drive" by some of the service reps I knew), where the common way to achieve stepped motion, lots of card punches and reader used that kind of a mechanism to move the cards, but they where not made of plastic and where generally faster and quieter than the one in this printer.
