 
 <prompt> Which one of these things no be device wey dey use stepper motors: computer printers, digital photocopiers, or servomotors? Given di last question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: Stepper motors dey use for 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. Also, many computer plotters (wey don dey replaced with large-format inkjet and laser printers since the early 1990s) dey use rotary stepper motors for pen and platen movement; the other options na either linear stepper motors or servomotors with closed-loop analog control systems.
