Hi, I have a Canon IP4000 for the last 1.5 - 2 years. Its worked
        

perfectly
    

till now.When I print a color picture, magenta doesn't show up. Black
cart.
shows some black on some part of the picture but not enough black on
        

other
    

parts where there should be. Green and yellow are OK. I checked magenta
cart. and sponge part at the side seems to be dry, but there is lots of
ink
in the cart. Black cart ink is ok too. I did cleaning and deep cleaning
        

a
    

few times, but on Nozzle check page, red and pink don't show up and
        

black
    

shows is gray.No errors show on screen and Status monitor shows all
        

carts
    

as
having enough ink. How can I correct this problem?

Replace affected ink tanks with new tanks. If that doesn't solve it,
      

remove
    

the head assembly and clean it with hot water and ammonia. (careful not to
dirty the electrical contacts on the back side). Do not leave the head
assembly out to dry, wipe if off and immediately reinsert and replace
      

tanks.

The ink tanks all have plenty ink so I don't want to buy new ones. I will
try the hot water and ammonia, though I am not sure what ratio the ammonia
to water is and if the water has to be hot. I've never done this before, but
I have some ammonia, so I will mix maybe 1 tablespoon of ammonia with 4
tablespoon of hot water and put it on the print head holes and see if that
helps..

the
    

head. If you can't get it running again, a new head assembly might be
needed, although it's not a certainty that this will fix it.
      

Ok, thanks. Its not under warranty so it might be cheaper to buy another one
if this one can't be fixed. Its only 1.5 or 2 years old so should have
lasted longer I would think. I haven't over-used it but I print 2 times a
week or sometimes more.

the 4000 is a well liked machine Mary. It seems that some would rather
have it than many of the newer models.
  

If you own one like I do and only use Canon ink there is little reason to change.  But if you are going to buy a printer than it is ridiculuous to buy one 3 generations old.  The IP4500 is current and produces a photo equal to if not better in quality and has led s on the cart to letyou know when to change the ink.  The ink is also a newer formulation that reduces the risk of fading.
