Class I laser products are not considered to be hazardous. The laser system and printer are designed so there
is never any human access to laser radiation above a Class I level during normal operation, user maintenance,
or prescribed service conditions. The printer has a non-serviceable printhead assembly that contains a laser
with the following specifications:
Class: IIIb (3b) AlGaInP
Nominal output power (milliwatts): 15
Wavelength (nanometers): 650–670

The power consumption levels listed in the previous table represent time-averaged measurements.
Instantaneous power draws may be substantially higher than the average.
Sleep Mode
This product is designed with an energy-saving mode called
Sleep Mode
. The Sleep Mode saves energy by
lowering power consumption during extended periods of inactivity. The Sleep Mode is automatically engaged
after this product is not used for a specified period of time, called the
Sleep Mode Timeout
.
Factory default Sleep Mode Timeout for this product (in minutes):
15
By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and 120 minutes.
If the print speed is less than or equal to 30 pages per minute, then you can set the timeout only up to 60
minutes. Setting the Sleep Mode Timeout to a low value reduces energy consumption, but may increase the
response time of the product. Setting the Sleep Mode Timeout to a high value maintains a fast response, but
uses more energy.
