  • Toner is smearing on the printed pages.
  • Repeated marks occur on the printed pages.
  • Printed pages are curled.
  • Toner flakes off the printed pages.
  • Printed pages have small unprinted areas.

  7. Select the option for the type of paper you are using, and then click the OK button.

Check the paper type setting (Mac OS X)

Check the paper type setting if you are having any of the following problems:
  • Toner is smearing on the printed pages.
  • Repeated marks occur on the printed pages.
  • Printed pages are curled.
  • Toner flakes off the printed pages.
  • Printed pages have small unprinted areas.
  1. On the File menu, click the Print option.
  2. In the Printer menu, select this product.
  3. In the Copies & Pages menu, click the Page Setup button.
  4. Select a size from the Paper Size drop-down list, and then click the OK button.
  5. Open the Finishing menu.
  6. Select a type from the Media-type drop-down list.
  7. Click the Print button.

Check toner cartridge status

If you determine that you need to replace a toner cartridge, print the supplies status page to find the part number for the correct genuine HP toner cartridge.

Print the supplies status page

Information pages reside within the product memory. These pages help diagnose and solve problems with the product.
observação:
If the product language was not correctly set during installation, you can set the language manually so the information pages print in one of the supported languages. Change the language by using the System Setup menu on the control panel or the embedded Web server.
  1. From the Home screen, touch the Setup button.
  2. Touch the Reports button.
  3. Touch the Supplies Status button to print the report.

Check the supplies status

Check the supplies status page for the following information:
  • Estimated percentage of cartridge life remaining
  • Approximate pages remaining
  • Part numbers for HP toner cartridges
  • Number of pages printed

Calibrate the product to align the colors

If the printed output has colored shadows, blurry graphics, or areas that have poor color, you might need to calibrate the product to align the colors. Print the diagnostics page from the Reports menu on the control panel to check the color alignment. If the blocks of color on that page are not aligned with each other, you need to calibrate the product.
  1. On the product control panel, open the System Setup menu.
  2. Open the Print Quality menu, and select the Color Calibration item.
  3. Select the Calibrate Now option.

Print a cleaning page

  1. From the Home screen, touch the Setup button.
  2. Touch the Service menu.
  3. Touch the Cleaning Page button.
  4. Load plain letter or A4 paper when you are prompted.
  5. Touch the OK button to begin the cleaning process.
    The product prints the first side and then prompts you to remove the page from the output bin and reload it in Tray 1, keeping the same orientation. Wait until the process is complete. Discard the page that prints.

Perform additional print quality troubleshooting

Print the print quality page

  1. From the Home screen, touch the Setup button.
  2. Touch the Reports button.
  3. Touch the Print Quality Page button.

Interpret the print quality page

This page contains five bands of color, which are divided into four groups as indicated in the following illustration. By examining each group, you can isolate the problem to a particular toner cartridge.
    Figura : Print-quality troubleshooting page bands
  1. Yellow
  2. Cyan
  3. Black
  4. Magenta
  • If dots or streaks appear in only one of the groups, replace the toner cartridge that correlates with that group.
  • If dots appear in more than one group, print a cleaning page. If this does not solve the problem, determine if the dots are always the same color; for example, if magenta dots appear in all five color bands. If the dots are all the same color, replace that toner cartridge.
  • If streaks appear in multiple color bands, contact HP. A component other than the toner cartridge is probably causing the problem.
If you have a defective cartridge or printhead, it might be under warranty. To check the warranty on your ink or toner supplies, go to Printer and Page Yield Overview, and then review the limited warranty information for your supplies.

Inspect the toner cartridge for damage

  1. Remove the toner cartridge from the product, and verify that the sealing tape has been removed.
  2. Check the memory chip for damage.
  3. Examine the surface of the imaging drum on the bottom of the toner cartridge.
      cuidado:
    Do not touch the roller (imaging drum) on the bottom of the cartridge. Fingerprints on the imaging drum can cause print-quality problems.
  4. If you see any scratches, fingerprints, or other damage on the imaging drum, replace the toner cartridge.
  5. If the imaging drum does not appear to be damaged, rock the toner cartridge gently several times and reinstall it. Print a few pages to see if the problem has resolved.

Check the paper and printing environment

Use paper that meets HP specifications

Use different paper if you are having any of the following problems:
  • The printing is too light or seems faded in areas.
  • Specks of toner are on the printed pages.
  • Toner is smearing on the printed pages.
  • Printed characters seem misformed.
  • Printed pages are curled.
Always use a paper type and weight that this product supports. In addition, follow these guidelines when selecting paper:
  • Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, staples, and curled or bent edges.
  • Use paper that has not been previously printed on.
  • Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet printers.
  • Use paper that is not too rough. Using smoother paper generally results in better print quality.

Check the product environment

Verify that the product is operating within the environmental specifications listed in the product Warranty and Legal Guide.

Check print job settings

Check the EconoMode setting

This product has an EconoMode option for printing drafts of documents. Using EconoMode can use less toner. However, using EconoMode can also reduce print quality. To improve print quality, verify that the EconoMode setting is deactivated.
  1. From the software program, select the Print option.
  2. Select the product, and then click the Properties or Preferences button.
  3. Click the Paper/Quality tab.
  4. Verify that the EconoMode check box is cleared. If there is a checkmark in the check box, click the check box to clear it.
HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable, consider replacing the toner cartridge.

Adjust color settings in the printer driver

Change the color theme for a print job

  1. On the File menu in the software program, click Print.
  2. Click Properties or Preferences.
  3. Click the Color tab.
  4. Select a color theme from the Color Themes drop-down list.
    Figura : Color tab
    • Default (sRGB): This theme sets the product to print RGB data in raw device mode. When using this theme, manage color in the software program or in the operating system for correct rendering.
    • Vivid: The product increases the color saturation in the midtones. Use this theme when printing business graphics.
    • Photo: The product interprets RGB color as if it were printed as a photograph using a digital mini lab. The product renders deeper, more saturated colors differently than with the Default (sRBG) theme. Use this theme when printing photos.
    • Photo (Adobe RGB 1998): Use this theme with printing digital photos that use the AdobeRGB color space rather than sRGB. Turn off color management in the software program when using this theme.
    • None

Change the color options

Change the color options settings for the current print job from the color tab of the printer driver.
  1. On the File menu in the software program, click Print.
  2. Click Properties or Preferences.
  3. Click the Color tab.
  4. Click the Automatic or Manual setting.
    • Automatic setting: Select this setting for most color print jobs
    • Manual setting: Select this setting to adjust the color settings independent from other settings.
      observação:
      Changing color settings manually can impact output. HP recommends that only color graphics experts change these settings.
    Figura : Color tab
  5. Click the Print in Grayscale option to print a color document in black and white. Use this option to print color documents for photocopying or faxing.
  6. Click the OK button.
