Which component in an inkjet printer is responsible for moving the paper through the machine?

The component in an inkjet printer that is primarily responsible for moving the paper through the machine is the roller. Rollers grasp the paper during the printing process, ensuring it advances smoothly through the print path. They play a critical role in maintaining proper alignment and timing to ensure that the ink is applied accurately to the paper.

The feeder is essential for loading the paper into the printer but does not actively move it during printing. The carriage belt is involved in moving the printhead back and forth across the page but does not interact with the paper directly. The printhead is where the ink is dispensed onto the paper, but it does not contribute to the paper's movement. Thus, rollers are the components dedicated specifically to the task of advancing the paper, making them the correct choice in this context.
