Page 8, Chapter 2, Power Line Disturbances
Reliable operation of your printer depends on the availability of relatively noise-free AC power.
● In order to ensure optimum performance and reliability, your printer should be protected from
variations in line voltage. Lightning, line faults or the switching of lighting or machinery can generate
line transients that far exceed the peak value of the applied voltage. If not reduced, these
microsecond pulses can disrupt system operation and damage the printer.
●
It is recommended to include overvoltage (OVP) and transient protection in the power supply to
the printer.
● All electrical noise-generating equipment, such as fans, fluorescent lighting and air-conditioning
systems, should be kept separate from the power source used for your printer.
The circuit breakers in the machine are apparently GFCIs according to the documentation. Does nothing to protect against transients or surges.
