Maximizing energy conservation in HP LaserJet M500 and M600 series printers October 5, 2011 Quickset: SMB – Small and Medium businesses with minimal central management The following steps, applied to an M500 or M600 series printer (via the Embedded Web Server) that is in factory default configuration, will set it up for minimal energy usage in a home, small or medium business environment where centralized remote management is not in use: 1) 2) 3) 4) 5) Energy Setting: Enable Sleep/Auto Off Time Energy Set

Auto‐Off/Auto‐On Technology The M551, M601, M602 and M603 HP Eco‐Smart LaserJet printers feature Auto‐Off/Auto‐On technology that dramatically reduces their power consumption. Auto‐Off/Auto‐On disables non‐ essential background functions to reduce power consumption to less than one watt when the printer is idle. The M500 and M600 series printers provide four power modes: When OFF, the printer will draw less than half a watt.
PAGE 4
In a typical office environment these printers can remain in Auto‐Off more than 70% of the time, when the printer and the user environment are configured carefully. The power states diagram identifies the events that cause the printer to enter and exit the Auto‐Off state: 1) The arrival of a Print Job or pressing the Power Button will wake the printer from Auto‐Off. Though these cause an increase in energy consumption, they are necessary activities for a printer.
PAGE 5
Energy Settings – Sleep Timer The Sleep Timer is the core control for the printer’s energy savings. It can be found on the Energy Settings page, Energy Settings Page and is comprised of three controls: A) The Enable Sleep/Auto Off Timer checkbox allows the printer to automatically enter Sleep or Auto‐Off after a period of inactivity. B) The contents of the Sleep/Auto Off After textbox specifies how long the printer waits, in minutes, after any activity before entering Sleep or Auto Off.
PAGE 6
Sleep Schedule When a Sleep Schedule is used to align the printer sleep time with off‐business hours, Wake/Auto On Events can only be set to All Events. Likewise, if Wake/Auto On Events is set to either Network Port or Power Button Only, Sleep Schedule cannot be set. When in use, the Sleep Schedule will only put the printer into Sleep. The printer will never go to Auto‐ Off and thus, to minimize energy usage, Auto‐Off/Auto‐On is recommended over Sleep Schedule.
PAGE 7
The M500 and M600 are configured by default to participate in such advertisement, waking the printer from Auto Off to Sleep. Disabling SLP Config will allow the printer to remain in Auto Off. SLP is not commonly used for printing services and this will generally have no impact. SLP Config can be disabled from the list in Network tab, Other Settings. Bonjour The Bonjour protocol is a decentralized services‐discovery protocol used broadly, particularly by systems developed by Apple Computer (e.g.

or report that no printers were found: In both cases, since the printer was awakened by the search process, applying the Search Again button will locate the printer. Installation and SNMP There are three common ways that Windows clients connect to printers,    HP’s Universal Printer Driver (UPD), the HP Standard TCP/IP Port or the (Microsoft) Standard TCP/IP Port. These methods connect to the printer through network ports that access and monitor the printer status.
PAGE 9
After installation, the ports continue to periodically monitor the status of the printer over SNMP. To minimize energy usage, this can be disabled. With the exception of the UPD, SNMP is optional for the operation of the print drivers.
PAGE 10
Disabling SNMP in the TCP/IP Ports If a printer was installed when SNMP was enabled, it can be disabled in the HP Standard TCP/IP Port and the Standard TCP/IP Port: Note that though you may be able to print if SNMP is disabled at the printer but enabled in the port, you may experience print delays as the port first attempts to gather SNMP information. Disabling SNMP in the port eliminates this delay.
PAGE 11
4) Scheduled activities, e.g. List Exports, Configurations, Firmware Upgrades, should be planned with the understanding that they will wake the printer. In addition, the delay of waking from Auto‐Off can result in WJA temporarily reporting Communication Error for that printer. Remote Management Appliance (RMA) RMA is used in Managed Print Service deployments to gather usage statistics for accounting using SNMP. Disabling SNMP is not possible in such deployments.
PAGE 12
Most applications are intrinsically tolerant of this delay and loss, using retransmissions or retries to operate robustly. However, custom applications may not expect this behavior and may need some modifications.
