Moving the printer

The printer is heavy and should be lifted by two people. One person should stand at the front of the printer, and the other person should stand at the back of the printer. To lift the printer, grip the lift handles that are on the sides of the printer. Do not attempt to lift the printer by gripping any other part of the printer. If the bottom of the printer is attached to an optional accessory (such as a 500-sheet feeder, a 1,500-sheet feeder, or a storage cabinet), the accessory latches must be unlocked before moving the printer.

WARNING! To prevent possible injury to yourself or damage to the printer, separate the printer from any currently installed optional accessories (for example, an optional feeder or a stapler/stacker) before lifting the printer.

Locking and unlocking optional accessories

For more stability to prevent the printer from tipping over, the optional 500-sheet feeders, the optional 1,500-sheet tray, and the cabinet can be locked to the bottom of the printer.

To lock the accessories, locate the lever on the upper left side of the optional feeder, and rotate the lever to the rear (locked) position.

To unlock the accessories, rotate the lever to the forward (unlocked) position.

CAUTION

NOTE

ENWW

Changing printer-control-panel configuration settings

By using the printer control panel, you can make changes to general printer configuration default settings such as tray size and type, sleep delay, printer personality (language), and jam recovery.

The printer-control-panel settings can also be changed from a computer by using the setting page of the embedded Web server. The computer shows the same information that the control panel shows. For more information, see Using the embedded Web server.

Configuration settings seldom need to be changed. Hewlett-Packard Company recommends that only the system administrator change configuration settings.

Changing control-panel settings

For a complete list of menu items and possible values, see Control panel menus. Certain menu options appear only if the associated tray or accessory is installed. For example, the EIO menu appears only if an EIO card is installed.

To change a control-panel setting

1.Press MENU to open the menus.

2.Use (UP button) or (DOWN button) to scroll to the menu that you want, and then press (SELECT button).

3.Some menus might have several submenus. Use (UP button) or (DOWN button) to scroll to the submenu item that you want, and then press (SELECT button).

4.Use (UP button) or (DOWN button) to scroll to the setting, and then press (SELECT button). Some settings change rapidly if (UP button) or (DOWN button) is held down. An asterisk (*) appears next to the selection on the display, indicating that it is now the default.

5.Press MENU to exit the menu.

Printer-driver settings override control-panel settings. Software program settings override both printer-driver settings and control-panel settings. If you cannot gain access to a menu or item, it is either not an option for the printer or you have not turned on the associated higher-level option. See your network administrator if a function has been locked (Access denied menus locked appears on the printer control-panel display).

Job storage limit

This option sets the limit for the maximum number of jobs that can be stored on the hard drive at the printer. The maximum number allowed is 100, and the default value is 32.

This option is only available if a hard drive is installed.

Tray behavior options

Four user-defined options are available for tray behavior:

●USE REQUESTED TRAY. Selecting EXCLUSIVELY ensures that the printer does not automatically select another tray when you indicate that a specific tray should be used. Selecting FIRST allows the printer to pull from a second tray if the specified tray is empty. EXCLUSIVELY is the default setting.

●MANUALLY FEED PROMPT. If you select ALWAYS (the default value), the system always shows a prompt before pulling from the multipurpose tray. If you select UNLESS LOADED, the system displays the prompt only if the multipurpose tray is empty.

●PS DEFER MEDIA. This setting affects how non-HP PostScript drivers behave with the printer. You do not need to change this setting if you use the drivers that HP supplies. If set to ENABLED, non-HP PostScript drivers use the same HP tray selection method as the HP drivers. If set to DISABLED, some non-HP PostScript drivers use the PostScript tray selection method instead of the HP method.

●SIZE/TYPE PROMPT. Use this item to control whether the tray configuration message and its corresponding prompts are shown whenever a tray is opened and closed. These prompts instruct you to change the type or size if the tray is configured for a different type or size than is loaded in the tray.
