Interface Cable Requirements
Data cables must be of fully shielded construction and fitted with metal or metallized
connector shells. Shielded cables and connectors are required to prevent radiation and
reception of electrical noise.
To minimize electrical noise pickup in the cable:
• Keep data cables as short as possible (6 foot [1.83 m] recommended).
• Do not tightly bundle the data cables with power cords.
• Do not tie the data cables to power wire conduits.
Caution •
Keep the power switch in the OFF position when attaching the interface cable.
The power cord must be inserted into the power supply and the power receptacle on the
back of the printer before connecting or disconnecting the communications cables.
Important • This printer complies with FCC “Rules and Regulations,” Part 15, for Class B
Equipment, using fully shielded data cables. Use of un-shielded cables may increase radiated
emissions above the Class B limits.
