    I only print black but it wants yellow. Just changed yellow. Changed it a month ago, too. Won't recognize it. Cartridge I just took out is still full of yellow. And it won't print. I'm about to throw it out.

After replacement of each ink cartridge the machine will display "Did you change?" for each colour. If one or more do not come up with this message you may have a problem.

Check each cartridge for the black flag is moving up and down with the liquid in the ink cartridge. If it stuck firmly tap it on a table until it is freed.

Another problem if the black sensors in the ink supply unit are pushed back it may not read the cartridges. If visably they look pushed back (usually only two) I can let you know how to correct.

Finally the mainboard in the machine can fail causing some inks not to read but you can not resolve this yourself.

Printer does not print in color but only prints in

Run a "print-head-cleaning-cycle" -- the ink inside the cartridges is not getting through the ink-jets, and is not reaching the paper.

Either that, or the electronics inside the ink-jets are malfunctioning, i.e., not telling the ink-jets to shoot the ink out.

Color cartridge won't print

sounds like when your in the print page, go to layout to either print in black or in color. i'm sure you've done this already but thought i would mention
also try this, take out the color cartridge and put back in. turn off all systems and turn on again to see if it reconfigures.
lastly, HP has an awesome web site for trouble shooting, check this out.
hope this helps and good luck

Won't print because color cartridge is empty and l don't need color

Try changing printing preferences/properties. Click on option for color, then click on box for "black ink only" or similar. Try now. If you still cannot print after changing preferences/properties, you will need to replace color ink cartridge due to manufacturer's built-in software that prevents printing when ink is low. Great for the ink companies!!!

Printer reads out "Print Cartridge problem (Tri Color) Refer to device documentation to trouble shoot" I purchased this HP Officejet J4550 All-in-one unit new and haven't made any color pictures with it....

I discovered on mine, exact same problem, I opened the tray, removed the cartridge, and forced it back in hard and fast. It didn't work the first 12 times but after that, it got a solid connection and it worked. Works fine now. Anyway that's the problem and the problem isn't the cartridge (genuine hp cart here). The problem is on the printer side, the pins that hit the cartridge. Anyway get rough with it, slam it in and out, close the tray, if it doesn't work within 5 seconds, open the tray and do it again. It WILL work.

Why won't my CX9400F recognize Epson ink cartridges

The Epson CX9400F printer seems to require replacement of all the color ink cartridges, even if only the Black is empty.

I print almost exclusively in Black, but with my first change of Black, I was forced to change all the color. At the time I thought Epson did not provide completely filled color ink cartridges.

Just yesterday, I replaced Black and the printer complained it did not recognize the rest of color cartridges. So I replaced all the other color ink cartridges and now it works fine.

You might want to check out for cheaper, mail order alternatives which are Epson ink compatible, if you are not in a hurry.

Want to print with black ink cartridge only

It is a little known fact that ink cartridges do have an expiry date, and it is sometimes possible that even if a printer reads full, that it has dried out and will not print. When you recieve a warning that your ink is too low you will simply be unable to print black ink after a certain point. Generaly if you want to print in only black you will have to do that when you print a document. For instance in IE when you go to file and then print you can select prefrences and select print in greyscale or black. hope this helps!

I have a epson stylus printer C65 series. I ran out of black ink so i changed the ink cartridge and it will only print colour not black now.

I have an Epson stylus 6000 series, second hand but was working just fine. I changed the ink cartridges and now the color won't print. Utilities shows all cartridges full, but only black and pale green-blue print. While it was printing color it was drinking the ink, but that's another story.
