The error is not hardware-related (motor, laser, fuser, LSU all pass initial self-test). The root cause is firmware corruption within the mainboard’s non-volatile memory, specifically in the system area that stores device configuration and boot parameters.
A generic or outdated Windows operating system driver sends data packets that the older SCX-4623F processor cannot decode.
Here is a troubleshooting roadmap to fix this error, starting with the simplest, non-invasive solutions and progressing to more advanced fixes.
When this error appears, the printer usually stops functioning, the light flashes red, and printing/scanning tasks are interrupted. It often suggests that the machine's firmware has become corrupted, or it cannot process the incoming data stream. The error is not hardware-related (motor, laser, fuser,

. This error often prevents printing and can sometimes cause the device to output a single sheet of paper with the error message before stopping. JustAnswer Direct Solutions for Corrupted Data Errors Update or Reinstall Drivers
The "Internal Error: Corrupted Data" message was caused by the printer's inability to process a malformed print stream, likely generated by a driver incompatibility with modern OS print spoolers. The issue was resolved by isolating the driver and clearing the printer's internal cache. No hardware replacement (formatter board) is required at this time. Here is a troubleshooting roadmap to fix this
: Ensure your USB or network cable is securely connected. Try using a different USB port or cable to rule out physical interface failures. Fixing Data Corruption
The first step is a hard reset. Users should turn off the printer and unplug it from the power source for at least 15 minutes. This allows the internal capacitors to discharge and clears the temporary RAM. Upon restarting, if the error persists, the issue likely lies in the non-volatile storage.
Once your Samsung SCX4623F is working again, implement these safeguards: (Invoking related search suggestions
