My pxma mp 600 canon printer is printing black lines through some of the lines on the page. I have tried all cleaning and alignment instructions in the manual. Did not help.

Hello,

It sounds like the print head on your printer is either clogged or not working.

You get faint print from your computer because the computer will use your color inks to get gray. When you copy, it only tries to use black and the black isn't printing at all.

Check your user's manual and it should show you how to clean the print head. Otherwise replace the print heads and you should be fine.

Thanks,

Pat

Hi. Probably the problem is the print head .

Please try to uninstall and reinstall your printer.

Clean your printer heads.

Perform a hard reset to your printer.

Print a test page.

Try using a different bond paper.

Make sure you are using original canon cartridge

If still you get an error. Replace your printer heads.

Usually I see that when you put in photo magenta when it should be plain magenta.Otherwise you need a new printhead.

Use the cleaning cycle first.If it completes do a nozzle check and then to align follow below.
You need to hook it up to computer to do a manual head align through the printer properties maintenance section.

i had the same problem and just repeated the cleaning and testing, eventually the black showed up but took more than a few repetitions

the colered pictures may be illegal to print like school pictures if you scan and then print them they will have a line threw them.

Perhaps the CMY color heads need alignment. If you have not already done so, run a head alignment from the driver maintenance section. It will print out a page containing several lines and text, and request you select the closest-aligned images. After this is done, do another image print to check for improvements.
Normally, the printer uses the black cartridge for text and the CMY inks for images (even for black on photo and specialty paper). So when you are printing normal text pages on plain paper, only the black ink is used. A good check for this would be to print a normal text page, but select photo paper in the driver to trick the printer into using the CMY inks to make a substitute black text page. If this looks ok, then you are having issues other than cartridge alignment.

Here's the link for how to clean the unit... I was going to post the instructions here, but there are pictures that might be helpful to you.

Before doing anything more drastic, I would try this.. let us know how it turns out.. if it doesn't work, we'll go from there.

(i posted this for someone before)

When you remove the black cartridge there will be electrical contacts inside the printer that lines up with some contacts on your cartridge, make sure these are clean

Also, according to this printers manual, have you tried a printer head align?

"(1) Open the Printer Properties dialog box. See Opening the Printer Properties dialog box directly from the Start menu
(2) Click the Maintenance tab.
(3) Click Print Head Alignment.
Follow the instructions on the screen."
