Abstract: Systems and methods of diagnosing a communication system within an industrial machine. The method includes receiving, from the industrial machine, communication system data of the communication system of the industrial machine and determining whether the received communication system data indicates an occurrence of a communication system issue. The method further includes determining whether the received communication system data includes one or more dismissive parameters in response to determining that the received communication system data indicates the occurrence of the communication system issue. The method also includes analyzing the received communication system data to determine whether a remote resolution to the communication system issue is available and transmitting the remote resolution to a user associated with the industrial machine in response to determining that the remote resolution to the communication system issue is available.

Abstract: There is disclosed an aqueous ink jet ink composition comprising an aqueous vehicle and a modified carbon product containing carbon having attached at least one organic group. The organic group comprises a) at least one aromatic group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The organic group having an aromatic group is directly attached to the carbon by the aromatic group. The organic group may comprise a) at least one C.sub.1 -C.sub.12 alkyl group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. Ink jet recording methods applying an ink jet ink of the present invention are also described.
