SOURCE: Canon iP5000 not printing black

Here is the link to the user guide if you need it; http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=257&modelid=10439 If you have performed all the operations in there with no success, then the part of the printhead that is under the 6bk has some blockages. This is best cleaned by dripping some ink flush solution (use gin if you have none) into the print head from above (just at the point where the hole on the ink cartridge would sit. Very gently swab with a q-tip from below with more fluid. After a day or so with the fluid penetrating from the top, clean the bottom again, clean out any excess fluid you can from the top (don't get any q-tip fluff in there). Then run a clean/test again. Hopefully this can solve your problem after a few cleans, but blocked Canon printheads are not always unblockable. You can purchase the complete replacement printhead, although I wasn't able to find a price - this link for service; http://www.usa.canon.com/consumer/controller?act=ServiceLocatorAct&fcategoryid=184&modelid=10439 Hope this helps :)

SOURCE: The 3eBK head stopped printing.

Try below some steps which might help you resolve the problem.

Print Head Cleaning / Head Refreshing If the printed Nozzle Check Pattern is broken, missing, or a specific color is not printed, clean the print head.

  1. Press the <Menu> button on the printers operation panel repeatedly until [MAINTENANCE] appears in the LCD.
  2. Press the left [<] or right [>] arrow buttons to select the cleaning setting you want. Select [HEAD CLEANING] or [HEAD REFRESHING] for deep print head cleaning.

    Note: [HEAD REFRESHING] uses more ink than [HEAD CLEANING], so perform [HEAD REFRESHING] only when necessary.
  3. Press the <OK> button.
  4. Print a Nozzle Check Pattern and perform at least two Head Refreshings if the pattern is not correct.
If this does not help, try removing the print head and then install it again. Once place, dont forget to aligh the head. Following are the steps:

Reseat Print Head Reseating the print head is seldomly needed to be done.
  1. Press the Open Button (1) to open the Paper Output Tray (2).

  5. Press <OK>. A horizontal pattern is printed.
  6. Beginning from column A on the printout, enter checkmarks in the patterns that have the most solid image.

    (1): Bad example (Least solid box)

    (2): Good example (Most solid box)

Check if there is a tape over the top vent intended to let air into the ink tank and so ink can flow out to the writing head.

Not printing red or pink


Hi patti,
Did you check the black ink cartrdige ???? To get red, their needs to be black ink involved which will darken the pink and give you red.

Also, make sure the nozzles are clean on the printer's print head. Take a Q-tip and alcohol and clean the printhead on the printer itself. Remove the cartrdige first. Clen the underside of the cartrdige as well.

Don't worry, alcohol won't harm the printheads because it dries instantly.
Hope It's resolve all Your Printer Problem,

Can't unclog black 3eBK nozzle.


If you said you replaced cartridges with new ones and it still doesn't work, the printer is the issue and may need to be replaced.

3eBk will not print. Canon MP780


Replacing the printhead may work, but it could be a problem with the cleaning assembly. Take out the 3ebk and run a cleaning, if the ink goes away on the pad where the ink cart. goes, then clean assy. is OK, and you need a new printhead.

Black ink 3eBk wont print


Ok what you need to do is make sure that the ink cartridge is properly inserted all the way. If it's not then you won't be able to print out black ink at all.

Canon ip4000r doesn't print 3ebk (black)


First of all... have you tampered with the printer's firmware? If not, it's unlikely it became corrupted. But if replacing the ink cartridges with fresh ones, and using a new print head did not fix your problem, you may be out of luck.

Is this a new problem, or has it always been like this?

Could it be that the print driver is always printing photo? In that case, it uses the narrow black ink cartridge instead of the fat 3eBK cart. You should print a nozzle check pattern and verify that you see the 3eBK cartridge pattern. If you do, the problem is likely SOFTWARE... your driver settings, not the printer itself.

I hope this helps.
