9.4 Relay Box
• A fire may occur if another manufacturer's external drying heater is used. Be sure to connect to
the machine using either the compact relay box or relay box 2 specified as options.
• The 330 series allows only one relay box (OPT-J0370 or OPT-J0407) to be connected.
• The optional connection relay cable (OPT-J0512 drying fan connection kit) is required when
using a relay box.

Overview
The relay box switches the heater power on and off automatically in conjunction with the machine
operations.
• The heater is turned off when printing stops to prevent heating while the machine is not moving.
• The relay box cannot function to control the temperature of an external drying heater. The temperature
should be set on the external heater itself.
