About Samsung 2161 ML 1666 ML 2161 SCX 3401 ML 1676 Laser Scanner Unit (LSU)

The Samsung ML-2161 Pickup Roller(often identified by part number JC93-00525A) is a critical mechanical component of the printer's paper feeding system. It is designed to grip and feed individual sheets of paper from the tray into the internal printing path.

Core Specifications and Material

Part Numbers: Commonly referenced as JC93-00525A and sometimes associated with JC61-04444A.
Material: Constructed with high-durability rubber on a specialized frame to provide the necessary friction for consistent paper grabbing.
Dimensions: Typical packaging dimensions for the roller kit are approximately 5.00 x 5.00 x 5.00 cm, with a component weight of about 200 grams.
Compatibility: While primarily for the Samsung ML-2161, it is also compatible with several other models including the ML-2160, ML-2165, SCX-3401, SCX-3405, and certain HP Laser MFP models like the 136a and 108w.

Key Functions

Accurate Feeding: Its primary role is to ensure precise, single-sheet paper pickup to prevent multi-sheet pulls.
Jam Prevention: A fresh roller reduces paper jams caused by worn-out, smooth, or "glazed" rubber surfaces that fail to grip paper.
Maintenance Indicator: If your printer frequently displays "Paper Jam" or "No Paper" errors despite having sheets in the tray, the pickup roller is often the first component that needs cleaning or replacement.
