Duty cycle is defined as the maximum number of pages per month of imaged output. This value provides a comparison of product robustness in relation to other HP LaserJet or HP Color LaserJet devices, and enables appropriate deployment of printers and MFPs to satisfy the demands of connected individuals or groups.
HP recommends that the number of printed pages per month be within the stated range for optimum device performance, based on factors including supplies replacement intervals and device life over an extended warranty period.

Not all “Compatible Operating Systems” are supported with inbox software. Full solution software available only for Windows 7 and newer. Legacy Windows Operation Systems (Vista, and equivalent servers) get print drivers only. Windows RT OS for Tablets (32/64-bit) uses a simplified HP print driver built into the RT OS. UNIX Modelscripts are available on http//www.hp.com (modelscripts are printer drivers for UNIX operating systems). Linux systems use in-OS HPLIP software. HP Software for Mac is no longer included on the CD, but can be downloaded from http://www.hp.com (the Mac driver and Mac Utility are installed for Mac operating systems).
Includes control panel height and 4mm side handle protrusions.
Acoustic values are subject to change. For current information see http://www.hp.com/support. Configuration tested: simplex printing using A4 paper at 43 ppm.
Power requirements are based on the country/region where the printer is sold. Do not convert operating voltages. This will damage the printer and void the product warranty. Power consumption values typically based on measurement of 115V device.

EPEAT® registered where applicable. EPEAT registration varies by country. See www.epeat.net for registration status by country.
Based on the BA TEC method with the following possible exceptions: 1 minute or less sleep delay setting, Wi-Fi disabled. Typical Electricity Consumption (TEC) rating represents the typical electricity consumed by a product during 1 week, measured in kilowatt-hours (kWh).
Declared yield value in accordance with ISO/IEC 19752 and continuous printing. Actual yields vary considerably based on images printed and other factors. For details see http://www.hp.com/go/learnaboutsupplies.
