I have a nearly new Lexmarkx3550 that won't print , I have new black ink but low on color. Why can't I print a story????????????

If your question means that you are not getting "nice" color copy ... it may be possible that your (color) ink is running low or empty. For instance, if your black ink is low or empty, you will not get the black colors printed ...
So, check to see if your ink cartridges are running low or empty. And if so, see if a (new) replacement cartridge will give you the same result.

In all likelihood your print head has become clogged at the black ink outlet. Be aware that printheads can BURN OUT if you keep trying to print and there's insufficient ink reaching the printhead. The ink flow is relied upon to prevent overheating of the tiny resistors at the printhead. Best bet is to remove the cartridges from the printhead and then remove the printhead and try to clean it in warm water. You will find many youtube videos on suggestions for cleaning the printheads on HP printers. Do a google search for your model. If all else fails you can order replacement printheads for the part that has failed. They are not cheap so price compare. Oftentimes they will cost nearly as much as a new printer!

You can only use the black ink cartridge without the color ink. But no need to replace them in your printer.
When you print just choose black and white for the printed text must be black not colored. But if you still received such notification...just try to replace the color ink cartridge to continue printing
Note: As per my experience. printer with exclusive black ink alone will damage the printer easily due to unbalance printing of ink

All brother machine have a one year in parts and labor this machine have a print head problem.

Did you try to wipe the cartridge.Maybe there's a clogs. inside.

If it show low or near empty it still print.
If it show empty it not print.
You can use black tape cover at ink catrige on position of sensor.
Many people do like that it work.

If not work send it to service center. it hardward problem.

My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected

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.

you need to print only in black if that is all the ink you have, and also you need to remove the color cartridge as it still registers in the printer as able to be used, although it is empty or near so. Did you remove the tape over the print head fron the new ink cartridge? Do a print head alignment, or use the toolbox icon to tell the printer that you just replaced the cartridge. Some HP models chip the ink cartridges so even a refill wont register as a full tank and the printer wont print. chip needs to be reset (difficult) or just replaced with a new cartridge.
