Hi: when I print the nozzle check, only prints 4 colors. lc, lm, y and c. Black and magenta were flushed but they dont work. The technician changed the printing process to 4 colors because i was having problems with magenta. The technician is out of the country and not coming back. He was the only one i knew. Now i dont know how to change it back and the printheads B & M doesnt work. Please help.

Most printers have 4 inks: Magenta, Cyan, Yellow, and Black. Red requires the printer to print both Yellow and Magenta. If your Magenta isn't printing, red will show up yellow. When you say, "I am not out of ink", you may actually BE out of Magenta, or your magenta ink nozzles may be clogged. I don't know what brand of printer or model you have, so I can't give you exact directions to clean the nozzles. The printer driver may have that ability.

Go to Canon website put in your printer model number an get the drivers an software for mac! hope this helps !

Most printers have 4 color inks: Black, magenta, cyan, yellow.
If your magenta ink isn't printing, then your prints will have a green cast.
If your printer has a "nozzle test", I suggest doing that. If it has a "head clean" function, that may help.
Replacing the magenta ink cart may be all that's needed.

Hi,
The inkjet printers print colors as they combine the major 4 colors contained in the cartridges CMYK (or said in words cyan, magenta, yellow and black) in some proportion.
If you print black the printer gets ink from the black cartridge only. If the black cartridge is empty some devices start to print black as a combination of the colors in the color cartridge - for example gets some of the cyan, gets some of the magenta, gets some of the yellow.
In your case maybe some of the other colors are empty too (or the nozzles are clogged) and the printer cannot prepare the correct mixture of colors to start printing black.
I suggest you to change both black and color cartridges.
Hope this helps.

This can happen if the ink dries out for a long time. Try to power flush the color that doesn't work.

Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

press 7 then 6 then 4 then start black copy. This will fill the tubes with ink.

press 7 then 6 then 3 then start black copy. You may use the right arrow to choose the color you want to flush before you press the black copy button.

Press 99 to exit maintenance mode

Press the ink button and do a test print for print quality and see if the color you flushed works. If not, try again.

This is the only way to fix the dried print head. Otherwise you have to replace the print head, in which case, you might as well buy a new printer.

Hi,

To determine if the cartridge set can produce the correct basic colors, run the "Clean The Print Cartridges" function under Services in the printer driver properties. The cleaning process will produce black, cyan, magenta, and yellow if both cartridges are good. If one or more of the colors is missing:
1. A cartridge has failed or is empty.
2. The print nozzles may be plugged, i.e. dried out or not being cleaned properly by the service station.
3. The cartridge and carriage electrical contacts may be dirty.
4. The printer may have failed.
If there is an incorrect color, the ink is mixed inside the color cartridge.

-- Do not continue until you have worked through any issues revealed above. --

After establishing that the printer is capable of producing the basic color set, print from a software application. If you are not getting the expected colors, consider these possibilities:
1. The software is not configured properly.
2. Uninstalling and reinstalling the printer driver.
3. The printer may have failed.

Try to perform a print head alignment.

1. Get compressed air
2. Run Printhead under HOT water, do not worry about contacts getting slightly wet.

3. Blow compressed air with straw attachment into screens where the cartridge nozzle sits on printhead. then let it sit and dry.

4. reinstall print test page

5. if this fails open paint/photoshop and print a page of the color that is not printing correctly. rinse and repeat until colors flow freely.

I have several ip4300s and I have yet to give up the ghost on a printer with a clog ujsing this method.

Hey Everyone!

I have an MP390 that had a similar problem over a year ago. There is a very simple fix that worked for me, and I'm pretty sure that it will work for you too. :^)

Outline:
Open the printer as though you were going to replace the ink tanks. Once opened, with the print head centered, open the latch and remove all of the ink tanks. Gently remove the print head (it should come right out, even easier than the ink cartridges). Take a paper towel, wet it with warm water, and then gently clean the bottom part of the print head. The bottom part is the part that will have an orange ribbon running to four metal openings that look like tiny nozzles. After wiping away all of the built-up gunk (on mine there was a thick sludge), grab a new and wet paper towel, and lightly press it against the nozzles. This should start sucking ink through the print head, and you will begin to see four distinct colors (CMYK) bleeding into the towel. Once done, lightly dry the print head off (make sure that there are no loose water droplets) and then reassemble everything. Print a test page and everything should work. If it doesn't change the ink tanks just to be sure.

Fortunately for you, Canon has made the print head on the MP390 very easy to service/remove, so cleaning is a snap.

Steps:

1. Turn Printer On
2. Open Printer As If To Change Ink Tanks
3. Release Ink Tank Latch
4. Remove Ink Tanks
5. Remove Print Head (Black Plastic Assembly In Which Ink Tanks Rest)
6. Use Wet Paper Towel (With Warm Water) To Clean Tank/Nozzle
7. Dry Excess Water
8. Reassemble
9. Close Printer
10. Print Test Page

Good luck!!!

Print first a nozzle check pattern, self test which they say. Check your manual for your printer, it should be accessible from that if you dont have any manual, go to the epson website and download a manual. Usually the self test would go like this.

While the printer is turned off, you press and hold down the paper feed button, continue holding it down while turning on the printer. It will print the nozzle check pattern standalone. If you see all the colors then the issue your having is a color management issue, if you do not see the cyan, magenta, yellow, black, light magenta and light cyan from that test; then you will need to do 3 consecutive times of Head Cleaning from the maintenance program in your computer. If you have a windows xp it goes like this.

Click on start go to control panel - printers and faxes -
you right click on your printer icon and select printing prefrences. From there, go to maintenance tab and click head cleaning, go through that cycle 3 consecutive times and see if it improved. Good luck....
