4500–E320/E322

Host interface error

This error is generated when the printer detects an error
communicating with the host computer. There are three causes of
this error:

1. Parallel external network adapter (ENA) connection is lost

during the printer’s power–on cycle. Once a connection is
initially established, a printer setting is modified to note that the
connection exists. Then, each time the power is cycled on the
printer, if the setting states a connection exists, the printer
attempts to communicate with the adapter. If the adapter does
not respond, a message is posted.

This error is only detected during the power–on cycle. This
means if the external network adapter connection is lost after
the power–on cycle is complete, this error is not detected. The
printer cannot distinguish between an adapter which is quiet, for
example, not sending any data, and an adapter which has been
disconnected.
