The SC541 error appears when the control panel locks up immediately after powering on. Listen for abnormal noises from the rear of the device. Verify that the power cord is plugged into a stable outlet, avoiding the use of overloaded power strips or faulty UPS systems.

Solución paso a paso

  1. Turn off the main power switch and wait for 60 seconds to ensure full system discharge.
  2. Power on the machine again to check if the error was a transient reading issue.
  3. Enter Service Mode by pressing: [Reset] -> [1] -> [0] -> [7] -> [C] (hold down).
  4. Reset the code by navigating to [Copy SP] -> [5-810] (Fuser SC Reset) and select 'Execute'.
  5. Reboot the device to confirm the error has been cleared.
