Data Cable Requirements
Data cables must be fully shielded 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.
• Do not bundle the data cables tightly with the power cords.
• Do not tie the data cables to power wire conduits.
Note • Print engines comply with FCC Rules and Regulations, Part 15, Subpart J, for Class A
equipment, using fully-shielded 6-foot (2-meter) data cables. Use of longer cables or
unshielded cables may increase radiated emissions above the Class A limits.
