IP4300 only recognizes magenta OR cyan

Worn print head. And for what they charge for a stinking print head you can get a new printer for less with a warranty to boot!

1. New original ink tank will dried for several times of head cleaning procedure.

. ....ran a nozzle check and cleaned print heads because it wasn't printing any ink on the paper.... ???
Nothing at all? If yes, problem is in the printer main board. Lost electricity to the head.

the magenta print head must be blocked. have it checked canon pixma ink

> replaced the print head

Did you replace the tri-colour ink-cartridge, or did you replace the print-head mechanism?

Are you sure that the CYAN part of the ink-cartridge is not empty?

Take the print head out of the machine and sit it in a saucer of very hot ( just off boil) water about 10mm deep for a minute. Take it out and sit in on a pad of paper towel to dry briefly before returning it and the cartridges into the machine. Give it a deep clean and try again. If still no good, the print head has probably had it.

Cleaning your head might resolve your problem. Perform the below steps to clean the head:

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 (Cleaning) or print head deep cleaning (Deep Cleaning). Note:

1. Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount of ink in the ink tanks.
   
   
2. Print head cleaning is performed when you connect the power cord. Your machine may perform print head cleaning periodically to avoid clogging.
   

Overview:
Step1:
Print the Nozzle Check Pattern.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is poor, perform print head cleaning.
Step 2:
Perform print head cleaning.
This unclogs the print head nozzles
Print the Nozzle Check Pattern again.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is still poor, perform two print head cleanings.
Print the Nozzle Check Pattern again.
Step 3:
Perform deep print head cleaning.
This is a more powerful cleaning.

In both cases be sure using correct ink. Use of generic ink can lead to leakage of catrridge seats do to crossion from inferrior ink quality (per Cannon). Be sure ink in proper locations - see manual. Run the maintenance proceedures: cleaning then print nozzle pattern. If all colors are not proper after two or three cleanings, perform deep cleaning. Print nozzle pattern after each cleaning. This should clear up problem. If not, print head may need replacement.

I find the best way to clean the heads is buy some cleaning cartridges as they have cleaning fluid in them and use them to clean it will take about 10 or more times to clean the heads then put the color ones back in and try again.
Just keep putting it on clean the head don't do a print out till at lest you have cleaned 10 or more times.

I hope it helps!!!

I'm not an expert but I go through a lot of ink.. I have found that even with new ink some of the tanks of ink aren't any good especially with compatible which i buy a lot of because it's a lot cheaper (ebay). With that ink I have gone through 10 cartridges in a row before finding one that worked correctly again (I mean out of 100+ cartridges hitting a run of 10 that where bad but the rest good.)

Also, a tech for epson once told me to hit deep clean 7 times in a row before a head check to clean their nozzles.. That has helped with my printer and at Fry's electronics, they have a cleaning solvent in kit, haven't tried it, but i have run alcohol through mine but I'm told that is very ******* the print head (dissolves the glue).

Hope that helped..
