Network Print Server Attachment Pin 18 +5 V Jumper Location and the
Parallel Connector
The NPS Ethernet 540+ can be used without an external power supply only if +5 V dc is enabled (supplied) on
pin 18 of the printer parallel attachment connector. NPS devices (p/n 30H4082, 30H4083, 30H4055) cannot be
powered by pin 18 and always require an external +12 V ac power supply. There is no danger of damaging any
NPS or other computer devices when +5 V dc is enabled on pin 18. The new logic board you receive will have a
2 pin jumper installed on either a 2 pin or a 3 pin connector located near the parallel attachment connector.
