Solving Duplexer Problems
1. Open the rear cover of the printer and inspect the inside of the duplexer for jammed paper or
obviously broken components.
Broken components or scraps of paper lodged inside the duplexer may be brushing against
moving parts and causing the noise.
2. Call your service technician.
This problem may be caused by a malfunctioning or broken component that requires service.
