OKI MB260 error 400: Fixing Memory and Data Issues

The OKI MB260 error 400 occurs when the printer fails to process an incoming print command, often due to high memory demand from complex files. This error forces the machine into a 'Data Error' state, preventing further jobs until the cache is cleared. Understanding this helps in managing network print loads effectively.
