The black in does not print. I have replaced it with a new cartridge. The printer thinks it's printing as it is passing back and forth over the page, but no black ink is printed! I have performed the standard Nozzle Check and Head Cleaning multiple times. Epson Stylus CXB400

When you say it won't accept the cartridge, is this what you are seeing?

The Incompatible Cartridge Incorrect Print Cartridge or Print Cartridge...

sounds like you replaced the black cartridge, do you run the "align print head" on the printer. Sounds like the black is not aligned to the printer input.

First run the CLEAN HEADS and see if that helps. If you don't use your printer at least once a week the Print Heads get dried out and will not allow the ink to pass through to the paper.
Go to control Panel and click on Printess. Then when the window comes up, CLICK on Properties TAB and then in the next window, CLICK on CLEANING.
You may have to replace your PRINT HEAD if that doesn't work.
Hope this is of some help. Bud

Printer heads, nozzles or carriage are kaput. Time for a new printer, they're cheap enough. Repairs will cost more than a new printer.
Epson.com sells cheap with free s&h

check printer preferences and settings.

It is called the print head.

Have you removed the protective tape that covers the printhead jets?

I came up with a work around for printing black.

I changed the black cartridge with the color cartridge.
Then when I have a letter to print, I change change (or write) the letter text to yellow, red or blue.
Then I can print out a letter.

By printing the text as yellow, red or blue the cartridge will try to print with only 1 color, but will print out black.

If you do not use one of these primary printing colors the out put will be unusable.

I can not of course print out pictures.

Hi lilacky-

Here are some HP support links that might be helpful... and a couple questions to consider.

Q: Is your new cartridge one of these listed below?
"The HP Officejet 6100 series and HP Digital Copier Printer 410 products use the print cartridges listed below:
* HP 56 black print cartridge
* HP 57 tri-color print cartridge
* HP 58 photo cartridge (replaces the HP 56 black print cartridge for six-ink photo printing)" info from: Installing a Print Cartridge

Has your cartridge been sitting a while in the box, maybe in a warm spot? Some times even new cartridges dry out a little. Was your old cartridge low or completely gone? Just as a test, if you put it back in your printer does the old cartridge work? Any printer error messages? Can you print a test page or an alignment page for your black cartridge? These might be too many questions but here are some HP support links with some How To information for getting more answers. Please let me know if any of these are helpful. see also: Slow or No Response from Printer

I had the same problem, and after scouring around online for a few days, I learned that this is one of the biggest gripes about this printer. Basically, you're out of luck unless you replace EVERYTHING, even though you only want to print black (nuts, isn't it?). So I went out and bought all new color cartridges, and it STILL won't print. I think it's just a bad printer all around. :(
