Supplies shelf life is approximately 2 years. This is based on storage in a standard
oce
environment at 22°C
(72°F) and 45% humidity.

Wet-bulb temperature is determined by the air temperature and the relative humidity.
Laser notice
The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR, Chapter I, Subchapter J for
Class I (1) laser products, and elsewhere is certified as a Class 1 consumer laser product conforming to the
requirements of IEC 60825-1:2014, EN 60825-1:2014+A11:2021, and EN 50689:2021.
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) AlGaAs
Nominal output power (milliwatts): 25
Wavelength (nanometers): 770–800
