did you get my questions?
Expert:  Russell H. replied 8 months ago.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

Is the problem that the print comes out in grayscale, like a black-and-white photo of something colored?

Or is the problem that colored ink doesn't appear to be getting onto the paper at all under any circumstances?

Customer: replied 8 months ago.

What color ink levels are shown, on an Ink Levels check?

Customer: replied 8 months ago.
I said I just put new color ink cartridges in this morning they are new it its shows full
Expert:  Russell H. replied 8 months ago.

OK, good.

Were those new cartridges put in because of the same problem showing up before they were replaced?

Has the printer had a period of disuse or storage lately?

Customer: replied 8 months ago.
no the old ones were empty

Then the nozzles may have dried up, that color ink goes through.

Try this procedure - patiently, for it will take several hours at least - to get the color ink flowing again:

In outline:

1. Clean the (color) printhead.

2. Wait 1/2 hour to several hours or overnight, leaving the printer On but unused (no print jobs, etc.)

This allows waste ink to soak into the printhead and hopefully dissolve dried ink etc.

3. Clean the printhead a second time.

4. Wait again (as in step 2 above) for 1/2 hr. to several hrs., printer On but unused.

5. Clean the printhead a third time.

Then test whether color ink is showing up at all in prints at this point. If it is, even faintly, then repeating this procedure will (eventually, at the cost of a certain amount of ink wasted in the process) clear up the clogged printhead.

After that fails, if it does fail, what you need to do is to decide whether replacing the printhead (which will cost something considerable, more than you would think usually) is better, given the printer's age, or whether it would be more preferable for you to replace the printer altogether with a new one (and hopefully recycle the old printer, always a good idea.)

So try the triple-cleaning-with-wait-times that I recommended, and get back to me if it doesn't work for you (so I can advise you further...)... or if it does help (- I always like to hear that something I recommended has worked!)
