This gear drives the roller that presses toner onto paper during the fusing process. When it breaks or wears out, the roller stops turning, causing paper jams and error codes. The problem is common in older Samsung monochrome laser printers and multifunction devices. Ignoring it can lead to more damage, like a blown fuser lamp or damaged pressure roller.</p>
