Back in the mid ’90’s one of my businesses used colour laser copiers worth $50k each. Located at the end of a long rural route the voltage would whiplash through a wild range depending on demand upstream (mostly low voltage). It kept blowing the $5,000 lasers out of the copiers until the techs realized the problem after installing a data meter. Problem was solved by installing an isolating voltage conditioner.
