Surge currents and transient voltages are responsible for damaging and degrading microprocessors in copier and facsimile machines. The problems resulting from this damage and degradation include paper jams, misfeeds, sorter errors, and transmission problems. EFI has designed a family of surge suppression products specifically for the protection of fax machines and 15AMP, 20AMP, and 30AMP copiers.

Recommended products for this application include the PowerTracker W100ES, W100ET, F-120-20E and F-220-20E.
