HP Photosmart C4340 All-in-One Series - Horizontal Streaks or Lines in the Printed Image

Issue
The product is working, but the printout contains streaks or lines. The lines are perpendicular to the direction the paper moved through the product, and parallel to the movement of the cartridges during printing.
Figure : Horizontal streaks or lines in the printed image
Solution
Follow these steps in the order presented to resolve the issue.
Step one: Check ink levels and replace low or empty cartridges
Follow these steps to check the ink levels, and then replace low or empty cartridges.
  note:
If you have installed a refilled or remanufactured print cartridge, or a cartridge that has been used in another product, the ink level indicator will be inaccurate or unavailable.
  1. Open HP Solution Center, if it is not already open:
    • Windows XP: Click Start, click All Programs, point to HP, and then click HP Solution Center.
    • Windows Vista: Click the Start icon (), click All Programs, point to HP, and then click HP Solution Center.
    • Windows 2000: Click Start, click Programs, point to HP, and then click HP Solution Center.
  2. In HP Solution Center, click Settings, click Print Settings, and then click Printer Toolbox. The printer Toolbox opens.
  3. Click the Estimated Ink Level tab. A graphic representing the estimated ink levels displays.
    Figure : Estimated ink levels
A cartridge may be running out of ink even if the graphic shows ink remaining. Lines or streaks appear in printouts when the cartridges begin to run out of ink. Replace cartridges that are low or empty.
  note:
Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low-ink levels, consider having a replacement ink cartridge available to avoid possible printing delays. You do not need to replace ink cartridges until print quality becomes unacceptable.
  1. In the program being used for printing, click File, and then click Print.
    The Print window opens.
  2. Make sure the appropriate product is selected, and then click Preferences or Properties.
    The Preferences/Properties window opens.
  3. Click the Printing Shortcuts tab.
    Consider modifying some or all of the options in the Printing Shortcuts menu to increase print quality.
    • Print quality: If the quality of the printouts is not acceptable, try increasing the print quality. To print more quickly, try decreasing the print quality.
    • Paper type: If one of the options matches the paper type exactly, select it instead of Automatic.
    • Paper size: Make sure that this option matches the paper loaded in the product.
    To see additional options, click the Advanced tab, and then click Advanced Features.
    The Advanced Features window opens. Consider changing the following option:
    Ink volume: Adjust the amount of ink that prints 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 more quickly the printout dries.
  1. Make sure plain white paper is loaded in the input tray.
  2. Open HP Solution Center, if it is not already open:
    • Windows XP: Click Start, click All Programs, point to HP, and then click HP Solution Center.
    • Windows Vista: Click the Start icon (), click All Programs, point to HP, and then click HP Solution Center.
    • Windows 2000: Click Start, click Programs, point to HP, and then click HP Solution Center.

  2. Press and hold the Cancel button () and then press the Start Copy Color button ().
    The product prints an extended self-test report.
    Figure : Extended self-test report
Identify which cartridge printed which part of the extended self-test report, so that if you find defects on the page, you know which cartridge is defective.
However, you can install different combinations of print cartridges in your product, and different cartridge combinations print different extended self-test report patterns.

  1. Printed by the right cartridge
  2. Printed by the left cartridge
  note:
If you are printing in reserve mode (one cartridge is missing), the area of the extended self-test report where that cartridge prints is blank.
The patterns in each area might look slightly different on your page.
Step six: Check for defects on the extended self-test report
In general, if the product and print cartridges are working correctly, the patterns, which look like grids of lines, contain few or no missing lines. Also, the colors of the patterns and bars should be approximately the same as the color dots on the print cartridge label.
  note:
Do not compare the colors on the extended self-test report to the colors on this Web page. Unless your monitor is calibrated, the colors are not the same. Instead, compare the colors on the page to the color dots on the print cartridge label. While the color dots might not be perfectly accurate, they are likely to be more accurate than the colors on the monitor.
If a pattern shows more than a few missing lines, or a bar is streaked, that print cartridge is not functioning correctly.
Figure : The magenta pattern shows missing lines and the bar is streaked - the cartridge is not functioning correctly
If the extended self-test report shows missing lines or streaked bars, click here to continue troubleshooting (c00832192) (in English).
The colors on the extended self-test report are printed by the tri-color (left-side) cartridge only. These blocks have labels describing the color they should be. If the color of any of the blocks does not match its label, the left-side cartridge is not functioning correctly.
    Figure : The color of one of the colored bars is very different from the color on the cartridge label - the cartridge is not functioning correctly
  1. Correct colors
  2. Incorrect color (yellow) - the tri-color (left-side) cartridge is not functioning correctly
If the extended self-test report shows colors that are different from the colors on the cartridge label, click here to continue troubleshooting (c00832204) (in English).
If any of the color patterns or bars are entirely missing, the cartridge is not functioning correctly.
  note:
If you are printing in reserve mode, without all the cartridges installed, the patterns associated with the missing cartridge will also be missing.
    Figure : Missing color bar
  1. All colors printed - no missing colors
  2. Yellow missing - the tri-color (left-side) cartridge is not printing correctly
If any of the patterns or color blocks is entirely missing, click here to continue troubleshooting (c00832204) (in English).
If the extended self-test report shows smeared ink, you might need to clean the cartridges.

If the extended self-test report showed smeared ink, click here to continue troubleshooting (c01438069) (in English).
If no defects were evident on the extended self-test report, the cartridges and product are probably working correctly. Click here to continue troubleshooting (c01302941) (in English).
