Electrical Interlocks
Equipment interlocks are devices which disconnect power to machine circuitry when a particu-

when a machine outer door is
opened and when internal assemblies are moved into their service position. This machine uses
the following interlocks:
• Front Door Interlock Switch (shown in F
igure 1

• Inverter Cover Interlock Switch (R/H) (shown in Figu
re 2)
• Drawer/IBT Interlock Switch
• Paper Takeaway Cover (L/H) Interlock Switch
