successful, proceed to the following step, “Verification.”
Verify Communication

• If the MIO Jet Direct Card has successfully powered up and completed its
internal diagnostics, the "I/O CARD READY" message will appear. If
communication is lost, an "I/O NOT READY" message appears followed by a
two digit error code. Consult the HP JetDirect Network Interface
Configuration Guide for further details and recommended action.
• The "Network Statistics" column indicate that the network activity has been
occurring. Bad packets, framing errors, un-sendable packets and collisions
should be minimal. If a high percentage (greater than one percent) of these
occur, contact the network administrator. All of the statistics are set to zero
when the printer is powered-off.
