    Check cable connections
    zMake sure both ends of the cable (USB, parallel, or network) are secure.
    zIf the printer is connected to a network, check the following:
     Check the Link light on the back of the printer. 
     Make sure you are not using a phone cord to connect the printer.
     The network hub, switch, or router is on and working properly.
    Check printer setup for network environment
    Ensure the correct printer driver and printer driver port are being used. For more 
    information about network connections, see Configuring the printer (Windows), 
    Configuring the printer (Mac OS), or the documentation provided by your network 
    vendors.
    Check any personal firewall software installed on the computer
    The personal software firewall is a security program that protects a computer from 
    intrusion. However, the firewall might block communication between the computer and the 
    printer. If there is a problem communicating with the printer, try temporarily disabling the 
    firewall. If the problem persists, the firewall is not the source of the communication 
    problem. Re-enable the firewall.
    If disabling the firewall allows you to communicate with the printer, you might want to 
    assign the printer a static IP address and re-enable the firewall. See Configure network 
    options.
    Printer does not accept printhead
    Inspect the printhead
    Remove the printhead and make sure the protective tape has been removed completely 
    from the printhead.
    Clean the printhead
    Complete the printhead cleaning procedure. See To clean printheads automatically.
    Turn off the printer after removing the printhead
    After removing the printhead, turn the printer off, and then turn on the printer without the 
    printhead installed. After the printer has restarted, reinsert the printhead.

    Printer takes a long time to print
    Check the system configuration
    Make sure the computer meets the minimum system requirements for the printer. 
    SeePrinter specifications.
    Check the port setting
    The port setting configuration in your system might not be set to ECP.
    See the documentation that came with the computer for information on how to change 
    the port setting, or contact the computer manufacturer.
    Check the printer software settings
    The printer prints slower when Best or Maximum dpi is selected as the print quality. 
    To increase the print speed, select different print settings in the printer driver. 
    SeeChanging print settings.
    Blank page printed
    Check media settings
    zMake sure the page settings in the printer driver matches the width and length of media 
    loaded in the tray. See Changing print settings.
    Check the parallel port on your computer
    If you are using a parallel cable, make sure the printer is connected directly to the parallel 
    port. Avoid sharing the port with other devices, such as a Zip drive or other printers.
    Placement of the text or graphics is wrong
    Check how the media is loaded
    Make sure the media width and length guides fit snugly against the edges of the stack 
    of media, and make sure the tray is not overloaded. See Loading media.
    Check the media size
    zContent on a page might be cut off if the document size is larger than the media that you 
    are using.
    zMake sure the media size selected in the printer driver matches the size of media loaded 
    in the tray.
    zIf you are using a computer running Windows, select Emulate LaserJet Margins in the 
    printer driver to print Laser Jet formatted document.
    Check margin settings
    If the text or graphics are cut off at the edges of the page, make sure the margin settings 
    for the document do not exceed the printable area of your printer. See Setting minimum 
    margins.

    Check the page-orientation setting
    Make sure the media size and page orientation selected in the application match the 
    settings in the printer driver.
    Check the Preserve Layout setting (Windows)
    If you are using an auto-duplex unit to do automatic duplex printing, ensure Preserve 
    Layout is selected in the printer driver. Clearing this option may result in unwanted 
    page breaks. See Printing on both sides (duplexing).
    Check the printer location and length of USB cable
    If the solutions do not work, the problem may be caused by the inability of the application 
    to interpret print settings properly. See the release notes for known software conflicts; 
    or refer to the application’s documentation, or contact the software manufacturer for 
    specific help.
    Poor print quality and unexpected printouts
    Check the printheads and ink cartridges
    Replace any clogged or worn printheads or low ink cartridges (see Maintaining the 
    printheads), and try to print again.
    Check the paper quality
    The paper might be too moist or too rough. Make sure the media used meets HP 
    specifications (see Selecting print media), and try to print again.
    Check the type of media loaded in the printer
    zMake sure the tray suppor ts the type of media you have loaded. See Understanding 
    specifications for supported media.

    Meaningless characters print
    If an interruption occurs to a job that is printing, the printer might not recognize the rest of 
    the job.
    Cancel the print job and wait for the printer to return to the ready state. If the printer does 
    not return to the ready state, cancel all jobs, and wait again. When the printer is ready, 
    resend the job. If prompted by the computer to retry the job, click Cancel.
    Check cable connections
    If the printer and computer are connected with a USB or parallel cable, the problem may 
    be due to a poor cable connection.
    Make sure the cable connections at both ends are secure. If the problem persists, turn off 
    the printer, disconnect the cable from the printer, turn on the printer without connecting the 
    cable, and delete any remaining jobs from the print spooler. When the Power light is on 
    and not flashing, reconnect the cable.
    Check the document file
    The document file may be damaged. If you can print other documents from the same 
    application, try printing a backup copy of your document, if available.
    Ink is smearing
    Check print settings
    zWhen you print documents that use much ink, allow more time to dry before handling the 
    printouts. This is especially true for transparencies. In the printer driver, select the Best 
    print quality, also increase the ink drying time and reduce the ink saturation using the 
    ink volume under the advanced features (Windows) or ink features (Mac OS) in the 
    printer software. However, note that decreasing ink saturation might give printouts a 
    “washed-out” quality.
    zColor documents that have rich, blended colors can wrinkle or smear when printed using 
    the Best print quality. Try using the other print mode to reduce ink, or use HP Premium 
    Paper designed for printing vivid color documents. See Changing print settings.
    Check the media type
    Some types of media do not accept ink well, ink will dry more slowly and smearing 
    may occur. See Selecting print media.
    Check the margin settings
    If you are using a computer running Windows, make sure the option to minimize margins 
    is not selected.
     
    						
    							ENWWPoor print quality and unexpected printouts     7 3     
    Clean the inside of the auto-duplex unit
    After extensive printing, ink might be deposited on the inside of the auto-duplex unit 
    causing ink to smear when printing on both sides of the paper. To remove the deposited 
    ink, use a lint free cloth to clean the inside of the auto-duplex unit.
    Enable the printers output ramp
    When printing in Fast Normal (default) or Fas t print mode, the printer does not use the 
    output ramp to hold each printed page before releasing it onto the output tray. If the printer 
    starts printing the next page while the printed page is still drying on the output tray, the 
    newly printed page might rub against the printed page on the output tray, causing ink to 
    smear. Severity of smearing depends on the amount of ink used on each printed page.
    To prevent the printed pages from rubbing against each other, print using the Normal or 
    Best print mode. Alternatively, enable the OUTPUT RAMP EXTENSION on the printer 
    control panel. See Paper Handling menu.
    Ink is not filling the text or graphics completely
    Check the ink cartridges
    Ink cartridges might have run out of ink. Replace any empty cartridge. Or try removing and 
    reinstalling the cartridges, make sure they snap firmly into place. See Replacing the ink 
    cartridges.
    Check the media type
    Some media types are not suitable for use with the printer. See Selecting print media.
     
    						
    							74    6 - Maintaining and troubleshootingENWW
    Output is faded or dull colored
    Check the print mode
    The Fast Normal and Fast modes in the printer driver allow you to print at a faster rate, 
    they are good for printing drafts. To get better result, select Normal or Best. 
    SeeChanging print settings.
    Check the paper type setting
    When printing on transparencies or other special media, select the corresponding media 
    type in the printer driver. See Printing on special and custom-size media.
    Check the ink cartridges
    If lines in the text or image are broken or do not print properly, one or more of the ink 
    cartridges may have run out of ink or are defective. Replace these cartridges with 
    new ones.
    Colors are printing as black and white
    Check print settings
    Make sure Print in Grayscale is not selected in the printer driver.
    Wrong colors are printing
    Check print settings
    Make sure Print in Grayscale is not selected in the printer driver.
    Check the printheads
    Whenever print quality noticeably decreases, you may need to clean the printheads. 
    SeeMaintaining the printheads.
    Printout shows bleeding colors
    Check print settings
    Some media type settings (such as Transparency Films and Photo Papers) and print 
    quality settings (such as Best) require more ink than others. Choose different print 
    settings in the printer driver, make sure you select the correct media type. See Changing 
    print settings.
    Check ink cartridges
    Make sure ink cartridges have not been tampered with. Refilling processes and the use of 
    incompatible inks can disrupt the intricate printing system and result in reduced print 
    quality and damage to the printer. HP does not guarantee or support refilled ink cartridges. 
    For ordering information, see HP supplies and accessories.

    Colors do not line up properly
    Check printheads
    The printheads are automatically aligned when a printhead is replaced. However, 
    you might notice improvement in the print quality by performing the alignment procedure 
    yourself. See Maintaining the printheads.
    Check graphics placement
    Use the zoom or print preview feature of your software to check for gaps in the placement 
    of graphics on the page.
    Lines or dots are missing from text or graphics
    Check printheads
    The printheads or printhead contact pads might need cleaning. See Maintaining the 
    printheads.

    For information on resolving jams, see Clearing jams.
    Tray cannot be inserted 
    zWith the tray removed from the printer, turn the printer off and then on again. 
    Reinsert the tray.
    zMake sure the tray is aligned with the printer opening.
    zCheck for jammed paper.
    Media is not supported for the printer or tray
    Use only media that is supported for the printer and the tray being used. 
    SeeUnderstanding specifications for supported media.
    Media is not picked up from tray 1 or tray 2
    zMake sure the media guides are set to the correct markings in the trays for the media size 
    you are loading. Also make sure the guides are snug, but not tight, against the stack.
    zMake sure media in the tray is not curled. Uncurl paper by bending it in the opposite 
    direction of the curl.
    zMake sure the tray is inserted properly.
    Media is not coming out correctly
    zMake sure the output tray extension is extended, otherwise, printed pages may fall off 
    the printer.
    zRemove excess media from the output tray. There is a limit to the number of sheets the 
    tray can.
    zIf the auto-duplex unit is not installed properly during a duplex job, media may exit through 
    the rear of the printer. Reinstall the auto-duplex unit or close its cover. 
    Pages are skewing
    zMake sure the media length and width guides in the trays are adjusted snugly against the 
    media, but do not crinkle or bend it.
    zAvoid loading media of different types or sizes in a tray.
    zMake sure media in the tray is not curled. Uncurl paper by bending it in the opposite 
    direction of the curl.

    Multiple pages are being picked up
    zMake sure the media guides are set to the correct markings in the trays for the media size 
    you are loading. Also make sure the guides are snug, but not tight, against the stack.
    zMake sure that the tray is not overloaded with paper.
    zWhen you load paper, avoid fanning the stack. Fanning paper can cause static electricity 
    to build up and intensify multiple-pick problems.
    zWhen reinserting a tray into the printer, do so gently. Forceful inser tion with a full stack of 
    paper may cause sheets to slide up within the printer, causing the printer to jam or pick 
    multiple sheets at one time.

    Troubleshooting installation issues
    If you had trouble installing the printer, check these items:
    Problems printing alignment page
    When printheads are installed or replaced, the printer automatically prints two alignment 
    pages to align the printheads. This process takes about eight minutes. The alignment pages 
    may be discarded after they are printed. If the printer does not print the pages, see General 
    troubleshooting tips, or align the printheads manually (see To align the printheads).
    Problems installing software
    Verify the computer requirements
    Make sure the computer meets the system requirements. See System requirements 
    (Minimum).
    Verify installation preliminaries
    zBefore installing software on a Windows computer, ensure all other programs are closed.
    zIf the computer does not recognize the path to the CD drive that you type, ensure you are 
    specifying the correct drive letter.
    zIf the computer cannot recognize the Star ter CD in the CD drive, inspect the CD for 
    damage. You can download the printer driver from http://www.hp.com/support/
    businessinkjet2800.
    Reinstall the printer software
    If you are using Windows and the computer cannot detect the printer, run the Scrubber 
    utility (located in the Utils\Scrubber folder on the Starter CD) to perform a clean printer 
    driver uninstallation. Restart your computer, and re-install the printer driver.
