(Precautions when using combination of NPN/PNP interfaces)
●
Use either NPN or PNP interface for input/output signals #4 to 5 and #14 to 23. Do not use a
combination of the interfaces for these input/output signals.
●
Interfaces can be combined for units of print material sensor signals (#1 to 3), encoder signals (#6 to 9),
input/output signals (#4 to 5, #14 to 18) and status output signals (#19 to 22).
(For example, PNP interface can be used for print target detector and NPN interface can be used for
status output signals (#19 to 22).
