HP Photosmart C6100 All-in-Ones Series - Streaks or Lines in the Printed Image

This document applies to the HP Photosmart C6150, C6170, C6175, C6180, C6183, C6185, C6186, and C6188 All-in One.

Problem

The printer is working, but printed output shows streaks or lines. The lines are perpendicular to the direction the paper moved through the printer.
Figure : Defect, with the direction the paper moved through the printer indicated

Step one: Check the ink cartridges

HP cannot guarantee the quality or reliability of non-HP ink. If ink cartridges contain non-HP ink, try replacing them with genuine HP ink cartridges. Once the ink cartridges have been changed it may take several pages for the print quality to improve as the printheads start using the new ink. Use the instructions in step four to help load the new ink into the printheads.

Step two: Check the printer settings

  1. In the software application you are trying to print from, click File, then Print. The Print dialog opens.
  2. Make sure your printer is selected, then click Preferences. The printer Preferences dialog opens.
  3. Select the Printing Shortcuts tab.
  4. The Printing Shortcuts menu list covers most printing needs, but you may need to modify some of the options.
    Click one of the printing shortcuts to select printing options for that shortcut:
    • Print quality - if you are unhappy with the quality of your printouts, try increasing the print quality. To print more quickly, try decreasing the print quality.
    • Paper type - if one of the options matches your paper type exactly, choose it rather than Automatic.
    • Paper size - make sure this matches your paper.
    For additional options: click the Advanced tab. Click the option and then select Change. Click the Change button.
    • Ink volume - adjusts the amount of ink printed on a page. For lighter images (less ink), drag the slider to the left. For darker images (more ink), drag the slider to the right. The lighter the ink volume, the faster the printout will dry.
    • Dry time - provides extra drying time for slow-drying printouts. Drag the slider to the left for less drying time, or to the right for more drying time. The printer will hold onto the printout until the dry time has elapsed.

Step three: Check the paper

  1. Many papers have printing and non-printing sides. Make sure to load the paper with the side you intend to print on facing down.
  2. Make sure the paper type is appropriate for your project. For everyday documents, plain paper works well. For documents with dense printing, such as high-contrast graphics or photographs, use HP Premium paper for the best results.
  3. If the steps above did not help, try a different paper. Ink may not bleed as easily on heavier weight paper. Paper that does not accept ink well is also prone to bleeding and smearing. HP inks and papers are designed to work together.

Step four: Clean the printheads

If none of the steps above solved the problem, follow the steps below to clean the printheads.
  1. Press the Setup button.
  2. Press the down arrow button until Tools is highlighted and then press OK.
  3. Press the down arrow button until Clean Printhead is highlighted and then press OK. A test page is printed.
  4. Examine the test page. If the print quality of the page is good, stop here. If the print quality is bad, go on to the next step for further cleaning.
  5. Open the Printer Toolbox. There are two ways to do this:
    1. Open HP Solution Center. Select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox.
    2. Open Printers and Faxes in the Windows Control Panel, then right-click your printer icon and choose Properties. Click Printing Preferences. Click the Features tab, then click the Printer Services button.
  6. The Printer Toolbox opens. On the Device Services tab, click Clean the Printheads and then follow the on-screen instructions. Up to three levels of cleaning are available. Discard or recycle the page that prints.
  7. If cleaning the printheads once does not help, follow the directions in step 6 to clean them again, but use the next level of cleaning.

Step five: Align the printheads

  1. Open the Printer Toolbox. There are two ways to do this:
    1. Open HP Solution Center. Select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox.
    2. Open Printers and Faxes in the Windows Control Panel, then right-click your printer icon and choose Properties. Click Printing Preferences. Click the Features tab and then click the Printer Services button.
  2. On the Device Services tab of the printer Toolbox, click Align the Printheads and then follow the onscreen directions.
