Before changing advanced settings
Keep the printer model, operating-system version and exact error message available. Do not share passwords, payment-card details, router-admin credentials or remote-access codes in support chat. Avoid firmware downgrades, router factory resets and hardware disassembly unless the printer manufacturer's instructions for your exact model specifically require them.
Windows users can also use Microsoft's current printer troubleshooting guidance. macOS, iPhone/iPad and Android users should use the operating system's built-in printer/scanner controls plus the manufacturer's official app or support documentation where the model requires it.
