Had the same problem - but the print head is actually easy to remove.
1) Remove ink cartridges
2) Remove 3 Phillips head screws at the bottom of the cartridge housing. (looking down from the printer front - top left, bottom left, top right).
3) There are 2 small plastic tabs on a plastic bracket that secure the flex cable on the right hand side of the cartridge housing. Gently release the tabs with a small flat head screw driver.
4) Lift the print head straight up (don't pull on the flex).
There may be a release for the flex to separate from the print head. But I did not see one. Instead I poured 1/4" of Windex in the bottom of a small plastic container and soaked my print head for about 15 minutes (occasionally agitating).
Then put back in reverse order - be sure to seat the flex in the guide (top-back-right) of the cartridge housing before screwing down. Then run a cleaning or two to flush the cleaning fluid out of the print head. (I have a waste ink tank installed so I am not worried about dumping excessive ink into the waste sponges).
The differences was remarkable - though there was still slight banding - maybe should have soaked longer (1 hr perhaps?) - I may repeat if it remains an issue.
Additionally there were large solid deposits on the left side of the print head which were responsible for scraping heavier weight photo paper. These dissolved in the Windex too.

Replace the cartridges.
Otherwise, it's unorthodox, but some users have found that this works in your situation. Remove the cartridge, cover the nozzle with a paper towel and use the pointed attachment of a vacuum to clean the dry ink from the cartridge. Be careful not to get ink all over. Then reseat the cartridge and print...
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Please remove the cartridges from the printer. Take a dry lint free paper towel and gently wipe the contacts on the back of the cartridge (not the bottom from where ink is present). Wipe the contacts inside the printer (on cartridge carrier). Please snap the cartridges back into the cartridge carrier and please try to print a printer self test.

Hi Yes you can try clean.
Ok it got to be the heads blockage
There is fluid cleaner for this but I can never find any in the shops the only ones I seen is when they sell them in Tesco but they come in with the ink refill bottles so I just use worm water by it self on a cloth and dabbing on the heads to clean them, it will not harm the heads but not to much water.
Some heads are on the inks them self but some have them inside the printer so I not know your printer so if the heads are inside you need to get them out you may find that some heads will just clip out put some need to be unscrewed so you got to know how they come out so be careful and not push to hard on them, if the heads are on the ink then it is a easy job to clean them,
It worth a try it worked for me more than ones.
Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on Helping.

SOURCE: print head clogged
Routine maintenance and keeping full ink tanks will prevent this problem, however if you have the problem you can resolve it by doing the following:
1. Clean your print head using denatured alcohol solvent which can be purchased from most hardware stores. If unavailable, use 91% Alcohol (isopropyl alcohol (first aid antiseptic) which is available for less than a dollar at most Walmart pharmacy departments.
*Warning: You may want to use a pair of latex exam gloves as this is a messy process and can stain your fingers.
Time necessary 45-50 minutes
Isopropyl Alcohol or denatured alcohol
sink, bowls and or basin
can of compressed air
very small screw driver
tablespoon or baby bulb type syringe
1. Lift print head from printer. It pulls out easily because it is held in with the same down lever that holds the cartridge in place.
2. Put two layers of paper towels in the bottom of a dish to protect sensitive sprayer heads.
3.Put enough solvent in dish to cover the screens on which the cartridges sit when in use.
4. Take the two small screws out that hold the white ceramic piece
5. Gently, pry the ceramic piece back and away , to reveal the underside (No need to pull away the glued points on the sides.)
6. Gently, move head up and down to slosh solvent around it the best as you can. Use a table spoon or syringe to pour solvent over all orifices in the print head, turning it upside down and then back a few times.
7. Use canned air with a plastic straw to blow into and through all orifices, alternately sloshing/swishing and pouring solvent over head (be careful not to touch any of the holes, screens, or sprayer heads with anything)
8. Empty dirty solvent from bowl and replace with paper towels and clean solvent. Soak for approx 10 minutes. Rinse again with clean solvent poured directly on all parts, letting solvent overrun and fall into dish or basin.
9. Gently shake the solvent off the head, take it outside and spray with compressed air into all orifices to clear out and help evaporate any remaining solvent. Let sit on a clean paper towel for approx 20 minutes. (There may be a little ink bleeding out of the head, but once it dries completely it does not present any problems.
10. Reinstall head, cartridges and it will print like a new printer.
SUGGESTION: For many years of problem free printing, keep a double set of ink cartridges, one set full at all times. Whenever a cartridge runs out of ink, replace it IMMEDIATELY, with a new one or a refilled one. This gives the print head no chance to dry out and create clogged heads. Routine maintenance of cleaning the heads every 24 months does wonders for keeping your printer in new condition.
Hope this helps. .
