DIY Components You Can Salvage from a Laser Printer

A discarded laser printer isn't just e-waste — it's a treasure trove of valuable components. Inside, you'll find high-performance motors, sensors, gears, optical modules, and power boards, all of which can be reused for various DIY projects such as robotics, automation, and electronics prototyping. In this post, we’ll explore the most useful parts you can salvage from a laser printer and how to repurpose them effectively.     1. Stepper Motors Laser printers include multiple stepper motors for paper feeding and precise positioning. These motors rotate in discrete steps and are ideal for projects requiring accurate movement control.
