Avoid damage from power line and telecom surges with the only surge protector made by Lexmark for its full line of laser printers and MFPs. Lexmark-grade surge protection Damaging power or telecom line surges result from utility transients and electrical line noise, as well as distant lightning strikes and general power line dips and swells. Typical consumer surge protectors are designed for general home and office electronics like PCs, TVs, VCRs and personal printers. However, based on their specifications, many don't address the high-current needs of laser printers and MFPs. The Lexmark Surge Protective Device is specifically engineered to protect Lexmark laser devices.
