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

I think you should try a certain cleaning procedure that I have found effective, first.

In outline:

1. Clean the (black) printhead. (This is a Maintenance function - let me know if you need guidance as to where to find it, either in the printer's Menu system, or in the printer's driver/software on the computer. It should not be done by hand... printheads are delicate.)

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 black 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!)

What do I use to clean it with?
Expert:  Russell H. replied 1 month ago.

A printer function, that works automatically for you, at about a minute per cleaning once you order it.

Is your computer a Windows PC?
