We did replace the black ink but unfortunately when we do printing their is no print. We already do cleaning several times.

Unfortunately, the printer does not actually measure the ink in the carts, but measures how many droplets called for. The carts may actually be full, but the printer now thinks they're empty. Most likely the black ink needs to be "charged" because you've cleaned out the pipe. I don't know what to do to charge it, and you'll likely need new carts.

reseat the ink catridge, let it warm up and test print again.

have you already replaced the ink of your black?..

Unfortunately, it's most likely that residual ink has dried and clogged the black print head. Plan on doing LOTS of cleaning cycles for the Black cartridge only if possible. It will consume lots of ink, so be prepared. After several cleanings and tests (as many as 10) you should see a gradually improving appearance of black. If not, try looking into the ink level counter to make sure it has reset to full as it shouls when you insert a new cartridge. If it is not, you sjould be able to change it. If that does not work, it's likely time for a new printer.

check the cartridge contacts in the printer \
a lot of time they geet covered in ink this will not allow the cartridge to print properly and cause headaches
clean with a baby wipe or a paper towel with soap on it
dry thuoly with hair dryer and try again

Ink button on? Check status monitor? I think is ink out message. Head cleaning for several time, throw ink too much. If u don't use CISS, after instaled ink tank, just wait for 1 hour before use printer. Ink will flow to head itself.

Assuming genuine ink cartThis worked for me on a HP printer 1.Try print black text ,and run many copies black only. I ran 25x12 times still no black. Run head clean after about each 50 sheets. Persevered and finally BLACK ink OK
Good Luck Inkypete

printer head problem remove ink put about ten drops of alcohol in where the ink goes in run clean cycle ten times

My printer worked fine since April but this week, I could not print. Thought my ink had dried up although I only replaced it just before christmas.

Bought new ink, installed it and still nothing. Calibrated, cleaned etc. etc. re-installed the disk to do maintenance and after several frustrating hours trying to fix it, I called my local Staples, the store at which I purchased this printer to ask for help.

First of all he said, what printer is it, black or white. I responded white to which he said okay that identifies the model for me. I am sorry to tell you that Kodak has acknowledged a problem with their print heads and have sent us several to replace the faulty ones. I said lovely, I wished I had known that several frustrating hours ago and he responded that it was his understanding that Kodak was going to announce this to all registered owners via a bulletin. Unfortunately I did not get it so wasted a lot of time. He requested I come in and get the new print head or if need be bring in the printer and they would install it for me. I am pleased with the store's response but not very happy with Kodak's lack of committment to get the word out.

Hope this helps.

It will only get worse. Do a google search and you will find out the print head is defective. After a multitude of complains, Brother has a more reliable print head for a fix. I'm not fixing mine. I've already invested too much in ink because of the auto cleaning it is programmed to perform.
A built in print head vs. a printer that has the ink tank and print head combined sounds like a good idea. The ink tanks are cheaper because they don't have the electronics built in and you only replace one color at a time. The problem is the print head clogs after several ink tanks have gone through them. Now, instead of paying $40 for a new ink cartridge with built in print head, you are paying for the ink that is wasted by all the required automatic cleanings, and eventually taking the printer to the repair shop for a new print head (parts and labor average $150) that may fail at any time.
My advice is to avoid any further headaches and buy a HP. Don't rely on good reviews, Consumer Reports rated this model a best buy.
