Cleaning the heads on printers is kind of a risky move, because, if you want to get them thoroughly clean, you'll have to actually take the cradle off of the rail, inside the printer, and use Q-tips with a tad of rubbing alcohol on them, or just use almost a full cartridge's worth of ink, to make it clean itself.

Not printing black


You didn't say printer name but it sounds like you have seperate cartridges! Most cartriges have connection points built in for the electricity to heat ink. You might want to see if the connection on both the printer and cartridge are clean.
some printers will tell you ink level! If yours tells you you have ink in the black then connection are good.
your test print must be missing the black, so I have also seen where multiple head cleanings may be required to unclog inkjet cartridge ports.
if not a manufacturers cartridge but refill you might want to try a new one.
Did you try selecting print black only? Like you are making a copy!
Sometimes HP cartridges have a small vent on top near rear that can clog use small pin to clear any vented buildup.

Also, what exactly did you clean, the metal contacts?

I have the Epson Stylus Pro 3880. Up till a few weeks ago all was well, the today, it decided not to print out the black areas of my shots. I've check the inks, the heads all is well. HELP


Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

Don't print the black color


Doing reference on your issue. Double check the ink cartridge to make sure that the cartridge is correctly installed. Also be sure that the black ink cartridge used is compatible with the machine.

The next thing to do is a cartridge cleaning as the belief is that the print head is blocked. If you have done a thurough cleaning, the next thing to do is replace the black ink cartridge to be certain the ink cartridge is not faulty.

I have included print head cleaning instructions in case you have not done this cleaning process.

here is some information from the Brother support site:

If one or more of the ink colors are missing from pages printed by your machine (i.e. received faxes, copies and/or documents printed from the PC etc), nozzles in the print head may be clogged, or the ink cartridge in question may not be installed correctly. Verifying that the ink cartridges are installed correctly and/or cleaning the print head may solve the problem.

Cleaning the print head may solve the problem. When cleaning the print head, you are given the option to clean BLACK ONLY, one of the three colors (CYAN, YELLOW, or MAGENTA), or all four colors at once. For this issue we recommend cleaning only the affected color. If more than one color is missing then choose ALL.

When the machine completes cleaning the print head, press Color Start. A Print Quality Check Sheet will print.

How can I get the fax and copy to print clearly?


Still sounds like a bad ink cartridge, try cleaning the bottom of the cartridge with a Kleenex and soapy water. Dry it off real good.

Look where the cartridge sits and clean the same way.

Ink jets are dead technology.

Printing problem


Since it sounds like you've gone through all the steps to clean the print head, I would suggest trying a new black cartridge. There may be a problem with the one you have.

The printer is not reading the cartridge properly. You may have clogged nozzles/printhead. Do a claen (deep or other) that is in your printers maintenace area. Then try to print. No luck, then remove cartridges, do a thorough manual clean by using proper cleaning solution and cotton buds(q-tips). If the cartridge has its own printhead (gold areas) wipe the gold area that goes against the printer carriage, ie the one the ink comes out of, be careful, do not wipe any other gold areas, only the one the ink comes out of. Press the cartridges firmly one by one on a folded wipe and hold a moment, when you lift off, you should be left with a clear vertical line of three colours, and the black one should be same but black. The marks should be dark and bright (ink) not patchy or missing colour etc. (i use unscented baby wipes-huggies!!! don't laugh they work great, i have never had printer problems apart from usual things like a toddler jamming it with toy!!!) Put cartridges back. Try reprinting. Good luck!!!
