Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Printing quality All of a sudden, shortly after I installed a new "yellow" cartridge, my printer started printing streaks. Except for the dirty marks, which done't seems to have the same pattern on each page, the print quality is excellent. Any ideas?

HP A636 will not print yellow; tricolor cartridge is new


  • Align the print cartridge.
The printer automatically aligns the print cartridge after a new one is installed. You can also align the print cartridge at other times to ensure optimal print quality. Indications that you need to align the print cartridge manually include borderless prints with white space
along an edge, colors not printing satisfactorily, or poor print quality.


To align the print cartridge from the printer
  1. Load a sheet of HP Advanced Photo Paper in the input tray.
  2. Touch the Setup icon to display the Setup menu. For more information, see "Setup Menu" on page 16.
  3. Touch Cartridge.
  4. Touch Align Cartridge and follow the prompts.

Clean the print cartridge automatically.
If the printed pages are missing lines or dots or contain ink streaks, the print cartridge might be low on ink or need to be cleaned.
CAUTION: Clean the print cartridge only when necessary.
Unnecessary cleaning wastes ink and shortens the life of the cartridge.

  • Clean the cartridge.
Follow these steps to clean the cartridge automatically:
To clean the print cartridge from the printer,
  1. Touch the Setup icon to display the Setup menu. For more information, see "Setup Menu" on page 16.
  2. Touch Cartridge.
  3. Touch Clean Cartridge and follow the prompts.
If the documents are still missing lines or dots after cleaning, replace the print cartridge.

hey payne


here is a copy of your problem.

Issue The printer is working, but colors in the printed output are missing, faded, or dull in comparison to the original. Solution Step one: Check the paper Verify that the paper type is appropriate for the project. If the paper is too fibrous, the ink applied by the printer might not fully cover the print surface. Step two: Check the print settings
  1. In the software application you are trying to print from, click File and then click Print . The Print dialog box opens.
  2. Verify that your printer is selected and then click Properties . The printer Properties dialog box opens.
  3. Click the Printing Shortcuts tab.
  4. In the What do you want to do? menu, select a task. The What do you want to do? menu lists most printing needs, but you might need to modify some of the options. Options on the Printing Shortcuts tab include:
    • 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.
    Additional options: click the Basics tab, then click Advanced Features . The Advanced Features window opens.
    • 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 ink levels NOTE: If you have installed a refilled or remanufactured print cartridge, or a cartridge that has been used in another printer, the ink level indicator will be inaccurate or unavailable.
  1. Open the Printer Toolbox .
    1. Open HP Solution Center .
    2. Click Settings .
    3. Click Print Settings .
    4. Click Printer Toolbox .
    NOTE: You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab and then click Service this device .
  2. Click the Estimated Ink Levels tab. Figure 1: Estimated ink levels - both cartridges low
99ac57c.gif If the steps above have not resolved the issue, print and evaluate a self-test page to determine if the cartridges or printer is causing the problem.
  1. Load the input tray with unused plain white paper.
  2. Press and hold the Cancel (c00636162.gif ) button and then press the Start Copy Color (c00636190.gif ) button.
  3. Release both buttons. The self-test page prints.
Step five: Note which cartridges printed which areas of the self-test page You must identify which cartridge printed which part of the self-test page, so that if you find defects on the page, you will know which cartridge is the problem. However, you can install different combinations of print cartridges in your printer, and different cartridge combinations print different self-test page patterns. Your self-test page may not look exactly like the picture below, but the right and left cartridges will print in the same areas of the page no matter which cartridges are installed. Step six: Look for defects In general, if the printer and print cartridges are working properly, the patterns (which look like grids of lines) should contain few or no missing lines. None of the colors should be missing and the colors of the blocks at the bottom of the page should match the labels below each block. Also, there should be no streaks of ink on the report. Missing lines or streaked bars If a pattern shows more than a few missing lines, or a bar is streaked, that print cartridge is not functioning properly. Figure 4: The magenta pattern shows missing lines and the bar is streaked 7e505a5.gif

No print with new cartridge on z1300


Try to remove and re-insert the cartridges into the printer carrier and make sure they are firmly inserted into the slot. Try to print again.
Print quality issues can be due to dirty or clogged cartridge nozzles. Try to open the Lexmark Solution Center on your computer to clean the cartridges.
On your computer, go to Start menu > Programs > Lexmark 1300 Series folder > Lexmark Solution Center. From the Maintenance tab, select Clean to fix horizontal streaks. Your printer will then print a test page forcing ink through the cartridge nozzles and clean them.
Try to print a document again to verify that the problem is fixed.

I have a 3800n that the print quality is very poor-meaning the background is gray streaks where the paper should be the only thing you see. Making the paper look dirty. hope that explains things. this...


You can try changing the print density under print quality in the control panel. YOu can also check the reset to factory default and see if this helps. It could need what is called a maintenance kit where the fuser and rollers are replaced. I install these all the time and sounds like this is what you need.

I changed my black cartridge, which was low. Now I get color bleeds, mostly yellow, in vertical streaks, on the printed paper.


Install the old black tonner back inside, if the yellow vertical marks disappear then the problem is in the new black tonner
