Magenta ink not printing. run all maintenance stages, fitted new cartridge to no avail

SOURCE: Magenta printing as yellow

Well, first off, are the alignment, and nozzle check sheets looking good? If not, then work on that. If so, then we have a problem. Try creating a test sheet in Word. Make red, yellow blue & black text and see if anything else prints wrong. Get back to me!

Disconnect the communication cable (USB?).

Turn off the printer, wait one minute then turn it back on,

Then press the left button on the panel, the transparent one to the left of power button. It will print a status page. Check the dates and information under each color that is failing.

The ink cartridges MAY be outdated. Printing the test and information page without the computer connected fools the machine since it can't get your computer date.

If the cartridges are outdated, then change your computer year back to 2005 or so, reconnect the printer cable and send something to print, once the printer prints it out, reset your computer to today's year.

You will need to do this procedure whenever you turns off the printer. (Disconnect cable, change computer year, print, reset computer date).

Hope this works.

SOURCE: Black 3ek cartridge not printing

I had the same problem before with 3e black ink. It simply does not print too, so what I did if i get to print black and white i will set the characters into dark gray! it looks like draft printing but the things is it can be printed.. I tried to do every instructions available but to fail. I almost dump it till I decided to set it aside for a while. After a week I tried using it again, and it functions well. I guess the printer just want to say, "HEY BUDDY, GIVE ME A LITTLE BREAK!"

SOURCE: iP4300 only recognizes magenta OR cyan

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.

SOURCE: one color is not printing properly ( magenta )

use a qtip and clean teh wipeoff area where the cartridge goes...
that and clean all around where the stripe may develop...
