I replaced the ink cartridge now ink is sqirting everywhere

Try to re-seat the cartridges into the printer. Remove both cartrdiges > . pull out the power supply (black box where the power cord is plugged in at the back of the printer) and put it back after 30 seconds > firmly re-insert the cartridges. Let it print the alignment page.

If the display screen shows "low black ink" again, then try to replace the black cartridge. The printer requires all cartridges to have sufficient ink in them to continue printing. Try to replace your black ink with a new one, preferably a genuine cartridge.

I can suggest you one thing. If you can't do it yourself, get a friend who can.
Make a small hole (using a drill) in a new cartridge. This hole should directly go to the ink cartridge. (Make sure you don't spill ink everywhere!) Make a similar hole in the old cartridge. Take a syringe and pull out some ink from the new cartridge. Put it into the old cartridge. If you can see the ink level, fill about half of the old cartridge this way. Close both holes. Now use the old cartridge in the printer!
(You can repeat this process whenever the old cartridge runs out of ink).

Printer heads, nozzles or carriage are kaput. Time for a new printer, they're cheap enough. Repairs will cost more than a new printer.

If you need to replace an ink cartridge in your printer, please follow the instructions below:

To confirm which ink cartridge requires replacement, please use the printer's control panel (there is a black ink out indicator, as well as a color ink out indicator ), or the Status Monitor in your computer.

Red light flashing - Low ink
Red light solid - Out of ink

1. Open the printer cover and press the INK (Cleaning) button for 3 seconds. The print head moves to the center and the lights flash.
2. Lift up the ink cartridge clamp. The cartridge rises up from its holder.
3. Remove the cartridge and dispose of it carefully. If ink gets on your hands, wash them with soap and water. If ink gets in your eyes, flush them immediately with water.
4. Unpack the new ink cartridge and remove the yellow tape. You must remove the yellow tape from the top of the cartridge. Do not remove the clear seal underneath the cartridge. Do not touch the green circuit board on the back of the cartridge, or you may inhibit normal operation and printing.
5. Tilt the new cartridge toward you slightly as you insert it. Lower the cartridge so that the tabs rest on the hooks. Do not place the cartridge tabs under the hooks.
6. Press down firmly on the ink cartridge clamp until it snaps in place.
7. If you need to replace the other ink cartridge, repeat steps 2 through 6 before continuing with step 8 (to move printhead over to color (if black was replaced first) press the cleaning button once).
8. Press the INK (Cleaning) button once, and close the printer cover. The printer begins charging the ink delivery system.
9. Wait until ink charging is finished (the power light stops flashing and the red error light goes out).

Complete the following instructions:

4. Remove the color print cartridge.
5. Lower the scanner unit until it is completely closed.
6. If the error message reappears, replace the black print cartridge with a new print cartridge.
   If it does not repeat steps 1-3 and then go to step 7.

If the cartridges are old too this may be a problem. When ink gets old it can clog the cartridges. If they are old replace them with new ones. If they are new ones did you peel the protective covering off before you inserted the cartridges? Hopes this helps
