    Changing printer settings from the control panel
    The control panel is one of three ways to set options in the printer. You can also change

    and application settings override control panel settings for the current print job. Application 
    settings override default printer driver settings.
    Menu items in the control panel are numbered from 1 to 9. If a menu has more than nine 
    items, the additional items will appear with a letter value from A to Z. However, the numbers 
    and letter values are not included in the procedures in this guide.
    For more information about any control panel menu or item, press   (Help button).

    submenus.
     Press   (Down Arrow button) or   (Up Arrow button) to highlight the desired setting, 
    and then press   (Select button) to save the setting. An asterisk (*) appears next to 
    the setting in the display, indicating that the new setting is now the default.
    3Press   (Cancel button) to exit the menus and return the printer to the 
    READY state. If no 
    button is pressed for 30 seconds, the printer returns automatically to the 
    READY state.

    Replacing the ink cartridges
    You can check the ink levels from the control panel or the embedded Web server. 
    For information about using these tools, see Overview of printer management tools. 
    After removing a cartridge from its package, install it right away. Do not remove a cartridge 
    from the printer for long periods of time.
    CAUTIONHP recognizes customer’s choice, but cannot guarantee the quality or reliability of non-HP 
    ink cartridges. Printer services or repairs required as a result of using non-HP or refilled 
    ink cartridges is not covered under warranty.
    NoteTo find out which ink cartridges work with your printer, see Supplies.
    To replace an ink cartridge
    1Ensure the printer is turned on.
    2Lift to open the ink cartridge cover.
     
    						
    							ENWWMaintaining the printheads     61     3Remove the ink cartridge that requires replacement by grasping it between your thumb 
    and forefinger and pulling it firmly toward you.
    4Remove the new ink cartridge from its package.
    5Insert the cartridge into its own color-coded slot. Press down firmly on the cartridge to 
    ensure proper contact.
    6Close the ink cartridge cover.
    Maintaining the printheads
    If printed characters are incomplete, or dots or lines are missing from printouts, this may be 
    caused by clogged ink nozzles and you might need to clean the printheads. To find out which 
    printheads work with your printer, see Supplies.
    When the quality of printouts deteriorates, complete the following:
    zCheck the health of the printheads.
    zInitiate the automatic printhead cleaning process.
    zManually clean the printhead contacts.
    zReplace the printheads, if the problems persist after cleaning.
    CAUTIONHP is not responsible for damage to the printer that results from modifying the printheads.
    To check printhead health
    NoteIf any printhead status is bad, clean or replace the printhead.
    zFrom the configuration page
    Check the printhead health section of the configuration page. See Understanding and 
    printing the configuration page.
    zFrom the embedded Web server
    1Open the embedded Web server. See To open the EWS.
    2Click the Information tab.
    3Click Ink Supplies in the left pane.

    To align the printheads
    Whenever you replace a printhead, the printer automatically aligns the printheads to ensure 
    the best print quality. However, if the appearance of your printed pages indicates that the 
    printheads are misaligned, you can align them manually.
    zFrom the control panel
    1Press   (Select button) on the control panel.
    2Press   (Up Arrow button) until MAINTENANCE is highlighted, and then 
    press (Select button).

    To clean printheads automatically
    NoteClean the printheads only when necessary; cleaning uses ink and shortens the life of the 
    printheads. There are three levels of cleaning available. After one level of cleaning, perform the 
    next level of cleaning only if the results are not satisfactory.
    zFrom the control panel
    1Press   (Select button) on the control panel.

    cotton swab. Before re-inserting the printheads, make sure all the electrical contacts 
    have had at least five minutes to dry.
    10Plug in the power cord and turn on the printer. The control panel should still indicate that 
    a printhead is missing.

    Resolving printing problems
    Printer shuts down unexpectedly
    Check power and power connections
    Make sure the printer is connected firmly to a functioning alternating current (AC) 
    power outlet. See Printer specifications for voltage requirements.
    All printer lights are blinking
    A non-recoverable error has occurred
    Reset the printer. See To reset the printer.
    If the problem persists, contact HP. See Support and warranty.
    Printer is not responding (nothing prints)
    Check printer setup
    See General troubleshooting tips.
    Check the printhead initialization
    When printheads are installed or replaced, the printer automatically prints two alignment 
    pages to align the printheads. This process takes about eight minutes. You can print 
    documents only after the automatic alignment pages have been printed.
    Check the printer software installation
    If the printer is turned off when printing, an alert message should appear on your computer 
    screen; otherwise, the printer software might not be installed correctly. To resolve this, 
    uninstall the software completely, and then reinstall the printer software. See Uninstalling 
    the printer software.
