Table 35. System setup submenu (CLJ 9500mfp) (continued) Item SLEEP DELAY Values 1 MINUTE 15 MINUTES 30 MINUTES *45 MINUTES 60 MINUTES 90 MINUTES 2 HOURS 4 HOURS Explanation
Use this item to set how long the MFP remains idle before it enters Sleep mode. Sleep mode minimizes the amount of power that the MFP consumes when it is idle and reduces wear on the MFP electronic components (turns off the display backlight). When you send a print job, press the control-panel key, open a tray, or open the top cover, the MFP automatically exits Sleep mode.

Note WAKE TIME
OFF* CUSTOM

Sleep mode turns off the backlight on the display, but the display can still be read.

Use this item to set the day and time that the MFP will automatically exit sleep mode. The custom setting allows you to set the day, hour, and minute (AM or PM) that the MFP will exit sleep mode. INACTIVITY TIMEOUT: The amount of time that the copy, send, or fax settings are kept before resetting to the defined settings. The value range, in seconds, is 10 to 300, and the reset default is 60. AUTO SETTINGS RESET: This option resets the copy, send, and fax settings when the START button is pressed. The values are OFF and ON, and the default is OFF. TIMEOUT AFTER SEND: The amount of time that a send setting is kept before resetting to the factory (default) settings. The value range is 10 to 300, and the default is 10. HOLD OFF PRINT JOB: If this value is set to ON, the print jobs will be held while you are using the MFP control panel. HOLD OFF TIME: This value controls how long a print job is held off after the copy/send job is complete. SCAN AHEAD: A copy job can be scanned even if the MFP is printing another job. The job is scanned and held until it can be printed. If SCAN AHEAD=OFF, the job will not be scanned until the print job is completed. AUTO JOB INTERUPT: A copy job can automatically interrupt any currently printing network print job in between the number of full copies printed. When this item is set to OFF, the copy job waits until the network print job is completed. COPY JOB INTERUPT: Interrupt the current copy job to make a different copy. When you press the START button, the MFP presents a message that asks if you want to interrupt the current copy job. When set to OFF, the current copy job cannot be interrupted by another copy job. AUDIBLE FEEDBACK: Gives an audible indication when a key is pressed or when you touch an interactive area of the touch screen. Use this item to select the default printing language (personality). Possible values are determined by which valid languages are installed in the MFP. Usually, you should not change the MFP language (the default is AUTO). If you change it to a specific MFP language, the MFP does not automatically switch from one language to another unless it receives specific software commands.

Installing firmware updates
Note Example firmware update file names in this section are the update firmware file for the HP color LaserJet 9500mfp. You must substitute the correct file name for the update firmware file for the your specific model. The MFP can use newer versions of its firmware as they become available. To obtain the latest firmware, go to one of the Web sites listed below, and follow the instructions on the screen. To download firmware updates easily to one or to many printers and MFPs, use the HP Web Jetadmin software (go to www.hp.com/go/webjetadmin). www.hp.com/go/lj9000mfp www.hp.com/go/lj9000Lmfp www.hp.com/go/lj9040mfp www.hp.com/go/lj9050mfp www.hp.com/go/clj9500mfp

Downloading the new firmware to the MFP
The MFP can receive an .RFU file update when the MFP is in the READY state. The MFP waits for all of the I/O channels to become idle before performing the update. Note The firmware update involves a change in the format of nonvolatile random-access memory (NVRAM). Any menu settings that are changed from the default settings return to default settings and must be changed again if you want settings that are different from the defaults. Examples of settings that are affected in this way are tray types, default symbol sets, and Web access alerts. The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the MFP to reinitialize. The I/O transfer time depends on a number of things, including the speed of the host computer that is sending the update and the I/O method (Fast InfraRed Connect [FIR], parallel, or network). The reinitialization time depends on the specific hardware configuration of the MFP, such as the number of EIO devices installed, the presence of external paper-handling devices, and the amount of memory installed. If the remote firmware update process is interrupted before the firmware is downloaded (when RECEIVING UPGRADE appears on the control panel), the firmware file must be sent again. If power is lost during the flash DIMM update (when UPGRADING PRINTER appears on the control panel), the update is interrupted and the message RESEND UPGRADE appears (in English only) on the control panel. The update must be sent only by a computer that is attached to the parallel port of the MFP. Finally, any print jobs that are ahead of the .RFU job in the queue are printed before the update is processed. Note Note The MFP automatically turns off and then on again after processing the update. HP LJ 9040mfp/9050mfp/9500mfp: If the firmware upgrade fails during the process, you might have to use the parallel port to instal the upgrade firmware. See "Remote firmware update through a local Windows port" on page 88.
