HP LaserJet 3300 series product 227

Performance Standard according to the Radiation Control for Health and Safety Act of 1968. Since 
radiation emitted inside this printer is completely confined within protective housings and external 
covers, the laser beam cannot escape during any phase of normal user operation. 

Using controls, making adjustments, or performing procedures other than those specified in this 
manual can result in exposure to hazardous radiation.

This equipment has been tested and found to comply with the limits for a Class B digital device, 
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection 
against harmful interference in a residential installation. This equipment generates, uses, and can 
radiate radio frequency energy. If not installed and used in accordance with the instructions, it may 
cause harmful interference to radio communications. However, there is no guarantee that 
interference will not occur in a particular installation. If this equipment does cause harmful 
interference to radio or television reception, which can be determined by turning the equipment off 
and on, the user is encouraged to try to correct the interference by one or more of the following 
measures:

●

Reorient or relocate the receiving antenna.

●

Increase separation between equipment and receiver.

●

Connect equipment to an outlet on a circuit different from that to which the receiver is located.

●

Consult your dealer or an experienced radio/TV technician.

Any changes or modifications to the printer that are not expressly approved by HP could void the 
user’s authority to operate this equipment.

Use of a shielded interface cable is required to comply with the Class B limits of Part 15 of FCC rules.
