Says replace ink cartridge

If you have used generic, or refilled cartridges, this probably the issue. You don't say what make or model, so it is hard for me to help you passed here. Newer copiers and printers are paricularly sensitive to non OEM cartridges.

Changing a printer cartridge is not complex but improper handling of the parts may damage the printer and the cartridge. If the user notices that while printing the ink comes out dry or faded, it may be time to change the ink or the toner. The user will know if it is time to change the toner because instead of a sharp image, one will get a faded image. It is time to change the ink cartridge when the printing comes out spotty or colors are used to replace others —for instance, blue for black or yellow for red. Remember, faded images signal the need to change the toner; spotty printing signals the need to change the ink cartridge get more help for change cartridge .
Hope this helps you.

Did you replace the ink cartridge with a new one, or did you refill an old one.

Some printers have a memory and can tell which ink cartridge is in them. This prevents them from easily being fooled into printing with refilled cartridges.

Another option is that you changed the ink cartridge without following the specific guidelines for replacement e.g. To replace the ink cartridge, select replace ink cartridge from the main menu, then open the printer panel when the light flashes X number of times.

You might also try unplugging the printer for a couple of minutes the reset it.

slowly off and on the printer for five times without cartridge, printer saves data of cart of last 5 only so next time it reads full ink..

Using some switch cleaner solvent, gently clean the contacts on the cartridge carriage, and also if you have any, use some inkjet cleaner to clean the nozzle where the cartridge sits, this should clean the mechanism sufficiently to allow the printer to detect the cartridge.

i replaced cartridges , error , said to replace cartridges. I then removed the new catridges, and now, can't drop the cartridge back in the scanner.HELP

as a printer mechanic .i had got many customers coming at my work shop with this problem .and it gets soved by replacing the cartridge with new cartridge.as you said cartridges are full still it says change cartridges.but if the circuit of the cartridge is got faulty it will not print let it be full.so clean the brown colour metal circuit on the cartridge with a dry tissue.if its due to dust got stuck up on the circuit it will print otherwise the cartridge has to be changed in this case.

The real problem is that the waste ink tank is nearly full

Now you can print again, but it has not solved your full ink-tank, that has to be solved in future.

On the front of the cartridge there is a sight tube for the ink, the fax shines a light through this tube to detect the ink.
I wraped a piece of paper around the tube to block the light beam on all the cartridges.
I dont need a processer to tell me if the machine is out of ink, I can work thay out when it stops printing!!
Now tell me you are out of ink you peice of electronic ****.

You can only fill ink cartridges up to a maximum of 3 times, thereafter the chip on he cartridge need to be replaced. That's why u are getting that message my advice order a new cartridge.
