Connecting Cables Correctly
Most cables come with some kind of locking device to insure that the
connection is made. Be sure to use these locking devices, otherwise you
may experience intermittent errors or the printer will fail to operate
altogether.
• USB cables are keyed and can only be inserted one way.
• When you have inserted a Parallel port connector, lock the connector by lifting up
the wire clips at either end of the socket so that they fit into the slots on the
sides of the connector.
• Ethernet 10/100 BaseT connectors have a locking tab similar to connectors on
telephone cords. When the plug is fully inserted, the tab clicks into place.
• RS-232 Serial connectors have screws on either side that should be used to
secure the cable to the printer.
Improperly inserted cables are the cause of many networking and printer-
related problems.
Universal Serial Bus (USB) Connection
USB connection ports can be found on nearly all new computers. USB
technology allows faster communication than traditional serial connections
and is easily expandable through interconnected hubs. All USB cables are
the same. One end of the cable fits into the computer or hub only and the
other end fits into the printer only. You cannot connect the cable incorrectly.
Bi-directional Parallel Connection
The bi-directional parallel connection between the printer and a PC
requires a standard 36-pin bi-directional cable (to IEEE 1284 standards).
The length of this cable can be up to 6.5 feet (2 meters).
