Minimum security settings for open networks
Ricoh does not recommend connecting a printer to an open network that is not secured behind a firewall or
router. This increases the risk of other people accessing printer functions, printing unwanted pages, or worse.
To avoid security issues, make sure the printer is connected to a secured network with a configured firewall or
router.
Ricoh recommends upgrading your printer to the latest firmware version. To obtain the latest firmware, go to
http://support.ricoh.com/services/device/qr/D0EW.html.
If you must connect the printer to an open network, change security settings to help reduce the risk of
unwanted access.
NOTE
: Available settings and menu names vary by printer model and firmware version. Refer to your printer
user guide for specific configuration options.
