70 6 - Maintaining and troubleshootingENWW 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.
ENWWPoor print quality and unexpected printouts 7 1 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. zMake sure you have selected the tray in the printer driver that contains the media you want to use. See Changing print settings.

72 6 - Maintaining and troubleshootingENWW 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.
ENWWPoor print quality and unexpected printouts 7 5 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.

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.
ENWWResolving printer management problems 77 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.
