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.
    

It seems quite obvious to me that you are using incorrect aftermarket ink and not the ink Canon recommends.  I have mentioned it before that these things would happen.  I have a Canon IP4000 and have had it twice as long as you have had yours.  I do not use it heavily but do manage to print a photo ever few weeks and at time more frequent.  I have never had to do any kind of a cleaning and have never had a problem with this printer.

Of course I use Canon ink and have never used any of the crap that I have researched on the Internet.  There are many vendors selling the same inferior product under different names and even using different websites to confuse the buyer and with almost no exception do not properly describe their product on every page.  Even when you call them they will not tell you what they are selling.  I have tried many times until I just gave up.

While I understand you unhappiness over the situation I do rejoice in these posts when I have forwarned users that these things happen and that I have never had a problem going on 5 years when I use the product according to Canons recommendations.  Still the people who have these types of problems will defend their action and still persist that I am wrong.  I think that is why I have pleasure when reading these posts.

The recommendation is to get a new Canon IP4500 and use only Canon ink.  The new Canon ink will have an even lower risk of fading.  I have not seen any fading but 5 years is not a long time for that.

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.

NO NOT continue to use the printer in this condition or you'll burn out 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.
