Starting troubleshooting
Start in this section if you are having a problem with the printer.
zIf you have a jam, see “Clearing jams”.
zIf you have a different type of paper-feed problem, such as the paper is skewing, it is not 
being picked up, or you cannot reinsert a tray into the printer, see “Resolving paper-feed 
problems”.
zOtherwise, if the printer is not working properly or if the print quality is not what you expect, 
try the following steps first.
 Check that the power cord is securely connected to the printer and plugged into a live 
electrical outlet.
 Check that the Power (green) light is on and not blinking. When the printer is first turned 
on, it takes approximately 45 seconds to warm up.
 Check that no other lights on the control panel are on or blinking. If lights are on or 
blinking, see “Printer lights reference”.
 Check that you can print a printer configuration page. See “Printing a configuration 
page”.
 Check that the USB or parallel cable between the printer and the computer or the 
HP Jetdirect print server is connected securely and functioning properly. To check the 
network connection, press the TEST button on the print server. An HP Jetdirect 
configuration page should print. See the HP Jetdirect Print Server Administrator’s 
Guide that came on the Starter CD to interpret the messages on the page.
 Check that no error messages appear on the computer screen.
 Check that you do not have too many programs open when your are trying to perform a 
task. Close programs that are not in use, or restart the computer before attempting the 
task again.
After you have tried these steps, see the following sections for information about more specific 
problems:
zResolving printer problems
zResolving printing problems (includes print-quality issues)
zResolving paper-feed problems (including skewing)
If none of these suggestions solve the problem, see “Support and warranty”.

Printing a configuration page
When you are experiencing a problem with your printer and you cannot discover the source of 
the problem, you can print a printer configuration page that provides more information about 
the problem. You can print the printer configuration page from the control panel. If you are 
using a computer that is running Windows, you can also print the printer configuration page 
from the Toolbox. If you have an HP Jetdirect print server installed, you can print a printer 
configuration page for the print server as well.
If you still cannot resolve the problem after reviewing the printer configuration page and trying 
the steps in the troubleshooting section, call the HP Customer Care Center. Keep the printer 
configuration page, because it provides information that might be useful to Customer Care 
Center in helping you to troubleshoot a printer problem.

Resolving printer problems
This section provide solutions to common problems that involve the operation of the printer.
Printer shuts down unexpectedly
Check the power
zMake sure the power cord is connected firmly to the printer and to a working outlet, and 
that the printer is turned on. The Power light on the control panel of the printer should be 
green. Try turning the printer off, and then on again.
zWhen the printer is first turned on, it takes approximately 45 seconds to warm up. Wait for 
the printer to warm up.
Check the printer vents
zThe printer vents are located on the left side of the printer. If the printer vents are covered 
and the printer overheats, it automatically turns off. Make sure the vents are not covered 
and the printer is in a cool, dry location.
Printer is not responding (nothing prints)
If you tried to print when the printer was off, an alert message should have appeared on your 
computer screen. If the printer was off and you did not see a message when you tried to print, 
the printer setup might be incorrect. To correct this problem, reinstall the software that came 
with your printer.
Check the power
zMake sure that the printer power is on. To turn the printer power on, press and hold the   
(power button) on the printer for a few seconds. After a brief printer startup, you should 
see a steady green light on the corner of the button. 
zWhen the printer is first turned on, it takes approximately 45 seconds to warm up. Wait for 
the printer to warm up.
Check the connections
zMake sure that the power cord is securely connected from your printer to a working outlet. 
If you still cannot turn the printer on, you might have a faulty power cord or control panel. 
Unplug the printer and call the HP Customer Care Center. See “Support and warranty”.
zMake sure that both ends of the cable (USB or parallel) are secure.

Check the printer setup
zCheck that the ink cartridges, and printheads are loaded correctly. Make sure that all the 
tape has been removed from the printheads. 
zCheck that the top cover and printing supplies cover are closed. 
zMake sure media is loaded correctly in the tray and that the media is not jammed in the 
printer.
zCheck to make sure that your printer is selected as the current or default printer and that 
Pause Printing is not selected. The default printer is the one that is used if you choose 
the Print command without first specifying which printer you want to use with an 
application. The default printer should be the printer that you use most often.
If the printer selection is a problem, open the Printers folder in Windows and set this 
printer as the default. In the Mac OS, set this printer as the default in the Chooser or the 
Print Center.
Make sure that your printer is properly set up in your network environment. 
zFor example, make sure that the correct printer driver is being used and that the correct 
printer driver port has been set. For more information about network connections, see 
“Connecting to a network” or the documentation provided by your network vendors.
All lights are blinking
A non-recoverable error has occurred
zFor example, the printhead carriage might be jammed. Try turning the printer off and then 
on again. If the printer does not recover, unplug the printer from the power outlet and call 
HP Customer Support. See “Support and warranty”.
Printer takes a long time to print
Check your system configuration
zMake sure that your computer meets the minimum system requirements for the printer. 
See “System requirements”.
Check your port setting
zThe port setting configuration in your system might not be set to ECP.
See the manual that came with your computer for information about how to change your 
port setting, or contact your computer manufacturer.
Check the settings
zIf the Type is set to Transparencies, or if the AutoSelect Type setting determines that you 
are printing transparencies, or if you chose Best mode, then printing will take longer. If 
you want these settings to be used, wait for the printer to finish. Otherwise, change the 
settings in the driver and print again.

Resolving printing problems
This section provides solutions to common printing problems.
A blank page printed
Check that the tape is removed from the printheads
zEach new printhead is packaged with protective plastic film covering the ink nozzles. 
Check each printhead and remove film if necessary.
zClean any excess adhesive from the contact area on the backs of the printheads with a 
clean, lint-free cloth.
Check for empty ink cartridges
zIf you are printing black text and a blank page prints, your black ink cartridge might be 
empty. See “Replacing ink cartridges”.
Check the printer setup
zIf the printer selection is a problem, open the Printers folder in Windows and set this 
printer as the default. In the Mac OS, set this printer as the default in the Chooser or the 
Print Center.
Check that the media you are using is wide enough
zThe media width must match the page settings in your print settings.
Check the parallel port on your computer
zIf you are using a parallel cable, make sure your printer is connected directly to the parallel 
port. Do not share the port with other devices, such as a Zip drive.
Something on the page is missing or incorrect
Check the margin settings
zMake sure that the margin settings for the document do not exceed the printable area of 
the printer. See “Setting minimum margins”.
Check the color print settings
zGrayscale might be selected in the Print Settings dialog box. 
 
						

							4-18ENWW
Placement of the text or graphics is wrong
Check the page-orientation setting
zThe page orientation selected might not be correct for the document you are printing. 
Make sure the media size and page orientation selected in the application match the 
settings in the Print Settings dialog box. See “Changing printer settings”.
Check the paper size
zThe Paper Size setting might not match the size of media you are using. Select the 
correct paper size from the printer driver.
zSome of the content might be missing or cut off if the document size is larger than the 
media loaded in the tray.
If the layout of the document you are trying to print will fit on a media size supported by the 
printer, then load the correct media size. Make sure to select the correct page orientation.
Alternatively, select Emulate LaserJet Margins in the printer driver to scale the 
document to fit the media size currently selected.
Check the margin settings
zIf the text or graphics are cut off at the edges of the page, make sure that the margin 
settings for the document do not exceed the printable area of your printer. See “Setting 
minimum margins”.
Check how the media is loaded
zMake sure that the width and length guides fit snugly against the left and bottom edges of 
the stack of media. For Tray 1, make sure that the tray is contains no more than 150 
sheets of media or a stack no thicker than 0.58 inch (15 mm). For Tray 2, make sure it 
contains no more than 250 sheets or media or a stack no thicker than 0.98 inch (25 mm). 
See “Loading media”.
If none of the above solutions worked, the problem is likely caused by the inability of the 
application to interpret print settings properly. Check the release notes for known software 
conflicts. Otherwise, check your application manual, or call the software manufacturer for 
more specific help for this problem.
 
						

							ENWW4-19
Poor print quality 
First try these general steps when you see poor print quality.
Check the printheads and ink cartridges
zReplace any clogged or worn printheads or low or empty ink cartridges (See “Maintaining 
ink cartridges and printheads”.) Then try to print again.
Check the paper quality
zThe paper might be too moist or too rough. Make sure that the media you are using meets 
HP specifications. (See “Selecting print media”.) Then try to print again.
Check the rollers that are inside of the printer
zThe rollers inside of the printer might be dirty, causing lines or smudges to appear on your 
printout. Turn off the printer, unplug the power cord, and clean the rollers inside of the 
printer with isopropyl alcohol on a lint-free cloth. Then try to print again. (Some printers 
might have a certain amount of aerosol on the inside wall after prolonged use. This should 
not cause lines or smudges on printouts.)
See the next sections for more specific problems:
zMeaningless characters print
zInk is smearing
zInk is not filling the text or graphics completely
zOutput is faded or dull colored
zColors are printing as black and white
zWrong colors are printing
zPrintout shows bleeding colors
zColors do not line up properly
zLines or dots are missing from text or graphics
Meaningless characters print
Check the cable connection
zA common cause for meaningless characters is a poor cable connection between the 
printer and computer. Make sure that the cable connection at both ends is good and that 
the cable is securely fastened.
zIf you are using a parallel cable or USB cable and the problem persists after you have 
checked the connection, turn off the printer and disconnect the cable from the printer. Turn 
the printer back on without the connection in place. When the Power light is on and not 
flashing, reconnect the cable.
Check the document file
zOccasionally, a document file is damaged. If you can print other documents from the same 
application, try to print using a backup copy of your document, if available.
Check the symbol set
zIf you are using DOS, use the DJCP to set the appropriate symbol set for the language of 
your document.
Cancel the job
zAfter an interruption has occurred to a job that is printing, the printer might not recognize 
the rest of the job. Cancel the current job and wait for the printer to return to the Ready 
state. If the printer does not return to the Ready state, cancel all job processes and wait 
again. When the printer returns to the Ready state, resend the job. If prompted at the 
computer to retry the job, click Cancel.
 
						

							4-20ENWW
Ink is smearing
Check the print mode
zWhen you print documents that use a lot of ink, you must allow the document more time to 
dry before handling it. This is especially true for transparencies. Select Best mode in the 
printer driver, and increase the ink drying time from Advanced Features in the printer 
driver. Under Advanced Features is an Ink Volume slider that you can use in conjunction 
with drying time to decrease ink saturation. 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 
Best mode. Try using the Normal, Fast Normal, or Draft mode to reduce ink, or use 
HP Premium Paper designed for printing vivid color documents.
Check the media type
zSome types of media do not accept ink well, which causes the ink to dry more slowly and 
results in smearing. See “Selecting print media”.
Ink is not filling the text or graphics completely
Check the ink cartridges
zTry removing and then reinstalling the ink cartridges, and make sure to snap them firmly 
into place.
zYour ink cartridge might be out of ink. Replace the empty ink cartridge. See “Replacing ink 
cartridges”.
Check the media type
zSome media types are not suitable for use with your printer. See “Selecting print media”.
Output is faded or dull colored
Check the print mode
zThe Fast Normal and Draft modes allow you to print at a faster rate. This option is good 
for printing drafts. To achieve better colored printout, select Normal or Best mode in the 
printer driver.
Check the paper type print setting
zWhen printing on transparencies or other special media, select the corresponding media 
type in the Print Settings dialog box.
Check the ink cartridges
zOn the printed page, check that all the lines in the text or image are connected and have 
printed properly. If the lines are broken, one or more of your ink cartridges is probably out 
of ink or defective. Replace those ink cartridges with new ones.
Colors are printing as black and white
Check the printer driver settings
zThe Print In Grayscale check box might be selected. From your application, open the 
Printer Properties dialog box. Click the Color tab and make sure Print in Grayscale is 
not selected.
