Change default passwords
Set a strong admin password on the printer's web page (Embedded Web Server). Default or blank admin passwords let anyone on the network change settings.
Keep firmware updated
Firmware updates frequently patch security holes. Enable automatic updates where available, or check the manufacturer's site periodically.
Turn off what you don't use
- Disable unused protocols and services (FTP, Telnet, raw ports) in the printer's web page.
- Turn off Wi-Fi Direct if you never use it, or set a strong password on it.
- Restrict or disable remote/cloud printing if not needed.
Protect sensitive printing
- Use secure/PIN release printing on office MFPs so documents only print when you're at the device.
- Clear stored scan/copy data and the address book before disposing of a device.
- Keep the printer off the guest network and behind your router/firewall.
Disposing of an old printer
Business MFPs can store copies of documents and address books. Use the manufacturer's data-clear/factory-reset and, for high-end devices, the secure disk-wipe option before recycling or returning a leased unit.
