I have changed and ink cartridge but dont know how to change settings as infomation still says low cartridge

May I assume you're not asking about an audio/video receiver? If that is the case, would you care to tell us what make and model device whose ink cartridge you want to change?

Try

Checking / changing Ink Cartridge Setting to 'Both Black and Color' in Windows

Replace Ink Cartridges
Your Epson Stylus NX110 Series and its software will let you know when an ink cartridge is low or expended.
If ink is low, the ink light flashes. You can continue printing until a cartridge needs replacement.
If a cartridge is expended, the ink light stays on. You must replace the cartridge to be able to print.
SEE IMAGE BELOW
Warning:
Keep ink cartridges out of the reach of children and do not drink the ink.
Note:
If you need to change a cartridge before it or any other cartridges are low or expended, run the Ink Cartridge Replacement utility.

You cannot print or copy when an ink cartridge is expended even if the other cartridges are not expended. Replace any expended cartridges before printing or copying.

Leave your old cartridges in the Epson Stylus NX110 Series until you are ready to replace them to prevent the print head nozzles from drying out.
When an installed ink cartridge is more than six months old, you may need to replace it if your printouts do not look their best, even after cleaning and aligning the print head.
Follow the instructions in these sections to check and replace your ink cartridges:

pls rate me. Thanks and Good Luck...

lift the lid while the printer is on and the catridges should bring themselves to the middle so you can access them easily. If they dont, try pressing the button which indicates low ink (it may be flashing if they need changing) and this will bring them to the middle.

Once you have the cartridges in the middle they will either clip out by pressing down on the side nearest to you or there will be a catch keeping them in place which needs lifting and then unclip them. Just do the reverse to place the new ones in.

If you need any further help or I have missed anything then please let me know and I will do what I can :D

hELLO THERE

Paper goes in the bottom tray in between the guides.

There is a handle just above the paper tray to open a door for changing cartridges.

it would be best to change them now

When you hear the fax ringing, press the start button. It sounds like you are not set to AUTO RECEIVE

with ours, it looks like there is ink in there, but it is not enough to register. When we put new catridges in, it fixes the problem
