    We have confirmed that Ricoh A3-sized multi-function printers, production printers, digital duplicators, Interactive White Boards, projectors, and Unified Communication Systems do not use IP stack modules from Treck Inc. and Kasago of Zuken Elmic, Inc. A small number of printers and A4-sized multi-function printers are still under investigation.

    The security and integrity of our customers' data and devices remain of utmost importance to Ricoh and will publish an advisory for the affected model. As more information becomes available, we will update this web page.
