Cleaning the print cartridge nozzles
To improve print quality, you may need to clean the print cartridge nozzles.
Clean the nozzles when:
• Characters are not printing completely.
• White dashes appear in graphics or printed text.
• Print is smudged or too dark.
• Colors on print jobs are faded or they differ from the colors on the
screen.
• Vertical, straight lines are not smooth.

Wiping the print cartridge nozzles and contacts
If the print quality does not improve after cleaning the print cartridge
nozzles, dried ink may be on the nozzles or contacts. To wipe the print
cartridge nozzles and contacts:
1 Remove the print cartridges. For help, see page 38.
2 Dampen a clean, lint-free cloth with water.
3 Hold the cloth against the gold nozzle area for about three seconds.
Gently blot and wipe dry in one direction (this prevents the colors in
the color cartridge from mixing).

change the black ink cartridge

Check under the cartridge holder. Sometimes fluff causes a ink buildup ink catridge and the cartridge holder. Clean under the cartridges and the cartridge holder

Good luck

How about nozzle check output? Is it perfect? No missing lines? Do head cleaning, wait for 30 minutes. Check nozzle again. If there are no difference betwen two output, you may need cleaning head manually.

It needs to be cleaned

Okay, this was the problem I posted a few days ago. It's fixed now, so in case you have the same problem with smearing, here's what the help desk from Canon suggested: Open the cover and remove the ink cartridges. There is a gray lever in front of the cartridges. Lift this lever and the printhead can be easily removed.
Our printhead had a buildup of black ink on the surface. I carefully removed this with rubbing alcohol. I let the printhead dry and replaced everything. No more smearing. Imagine a help-desk that actually helped!

you may try
1) clean the cartridge nozzles with dry soft paper
2) clean the cartridge carriage down side surface there might be bled ink.
3) check the cartridge up side there is the lable cover the ink refill hole is ok, no any lable stick there you need put stick lable there.

i had to run 10 cleaning to get a printer to print magenta. finally it cleaned it self..it gets expensive..leaving your printer on keeps the in nozzles clean..when its off for long periods it dries in the nozzles.

Ren, Does the printer show the cartridges have been changed? If the printer doesn't recognize the new cartridges, turn off the computer and unhook the printer, unplug the printer from the computer and electric. Turn on the computer so it boots without the printer hooked up,(2x) then shut down again. Rehook the printer and plug it in then reboot the system. http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_UseBVCookie=yes&oid=41661&prodoid=46048263&infoType=Downloads&platform=All You can also find updated drivers from epson from here.
