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>https://printer-parts.yourdomain.com/posts/the-ultimate-compatibility-guide-for-samsung-printer-fuser-roller-gears-and-bushings/Tue, 02 Jun 2026 00:00:00 +0000https://printer-parts.yourdomain.com/posts/the-ultimate-compatibility-guide-for-samsung-printer-fuser-roller-gears-and-bushings/<blockquote> <p>This guide explains how to identify and replace the upper fuser roller gear and bushing for Samsung ML-2160, SCX-3401, and M202 series printers. We cover compatibility, cross-referencing OEM part numbers, and installation tips to help you fix common fuser jams and gear wear issues.</p></blockquote> <h2 id="understanding-the-upper-fuser-roller-gear-and-bushing">Understanding the Upper Fuser Roller Gear and Bushing</h2> <p>The upper fuser roller gear and bushing are small but critical components in laser printers. The gear drives the fuser roller to rotate, ensuring even heat distribution for toner bonding. The bushing reduces friction and prevents wobbling. Over time, the gear teeth can strip or the bushing can crack, leading to paper jams, wrinkled output, or poor print quality. For Samsung ML-2160, 2165, SCX-3401, 3405, and M202 models, a common fix is replacing this part rather than the entire fuser assembly. The Upper Fuser Roller Gear with Bushing for Samsung ML-2160 2165 SCX-3401 3405 M202 (Product #1) is a budget-friendly option at $0.97, while the JC66-03080A JC61-03755A variant (Product #2) offers a slightly higher price at $1.08, both with no ratings yet but solid compatibility.</p>
