HP LASERJET ENTERPRISE 500 COLOR M551 SERIES
1
Measured using ISO/IEC 24734, excludes rst set of test documents. For more information, see http://www.hp.com/go/printerclaims. Exact speed varies depending on the system conguration, software application, driver, and document
complexity.
2
Exact speed varies depending on the system conguration, software application, driver and document complexity.
3
Duty cycle is dened 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.
4
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.
5
Toner cartridge yields established
using ISO/IEC test standards. Actual yields and costs vary considerably depending on images printed, number of color pages printed, and other factors.
6
Conguration tested: HP LaserJet Enterprise 500 color M551dn bundle tested simplex
printing, A4 paper at an average of 32 ppm.
7
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
in Auto-Off mode depends on customer network switch capability, user conguration and network activity. Off-mode power may vary while checking network packets for print jobs.
