I want to know the answer to the following question:
In scanners, what do stepper motors move?
All the background I'm provided with is that "Stepper motors were and still are often used in computer printers, optical scanners, and digital photocopiers to move the optical scanning element, the print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers.". Is that enough to answer the question?
Answer: yes
