Oh dear, I'm really sorry I didn't explain! Anyway, it just happened again and I googled it and came across my own post 🙂 Then I had to remember how to get back into manufacturing mode. You press * and # together and the display should show ********#######. Then you press 124 and should see Underware R2006N or similar, press right arrow to boot code menu, press ok and it should say "set to user_mode". Click right arrow and it should show "set to mfg_mode". Click ok and it should be in manufacturing mode. Now I just did that and it let me print with empty yellow, but it still shows as empty yellow if I go to the printer IP address in my browser. I'm sure it showed as full before. Anyway, I can print again. There are other hidden menus with *# then 123 also.
There's also a set to manufacturing mode in the *# 127 menu if you right arrow until it says "boot code menu", select it with ok, then there is "set to mfg mode" there too.
Ok, it printed one thing, but wouldn't print again. I don't think it is going into manufacturing mode and I'm not sure why.
I found another solution which is to cover the oblong hole on the cartridge with tape and it's now printing again.
Ok, now I have got it back into manufacturing mode. I unplugged the power and plugged it back in again and it went into manufacturing mode with all cartridges showing as full all the time. And I can print yellow funnily enough 😉

Thank you, thank you, thank you for the tip about the tape. I conquered my empty yellow cartridge with that, and gloated loudly over my printer with lanuguage I will not repeat on this board. I had some black and white (grayscale) printing that HAD to be done and while I have no idea where you begin those manufacturer's mode instructions, the tape solved my problem.
One day a printer manufacturer will be smart enough to empower the USER with respect to when ink gets changed. THANK YOU FRIPP505!

I used this as a work around. I filled the yellow cartridge with water 🙂 I only use it for black printing since one of blue printer head doesn't work. I was just trying to use up the new black cartridge before i chuck it out of a moving vehicle!

Instructions
Read the entire Instructions below before beginning.
Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill such as a sink. Be sure that you are wearing old clothes, since the first time you fill the cartridge, you will probably get some ink on your clothes and hands. You may wish to wear rubber gloves if you don't want to stain your hands. We also don't recommend refilling as a family project -- it's amazing what a three-year-old can do with a pint bottle of highly concentrated ink! Not to mention what Fido or MS. Kitty can do by bumping either their beloved person or the bottle. See our General Informationfor more details.
Step 2) Look at the cartridge. Near the bottom of the cartridge you will see a horizontal break line in the plastic where the two parts of the cartridge snap together.
Step 3) Using a sharp knife or scissor blade, cut the label on the front of the cartridge along the line where the two parts of the cartridge come together.
Step 4) Using a knife,screwdriver, or just your hands pry the cartridge open along the line. Let it hang by the backside label.
Step 5) The exit port is the point where the ink comes out of the cartridge. It has an obvious stem. Place this stem to your right.
Step 6) You will also see a rubber oval-shaped bulb. To the left of this bulb is the fill hole. You will see a small ball in this hole. Stick a pin or the end of a sharp knife into this ball and pry or lift it out of the hole. (Saundra recommends a sharp steak knife. (*** Don't stab or cut yourself!***) Don't lose the ball!
Step 7) Fill your syringe bottle with the appropriate ink. You'll need about 30 ml (1 full syringe bottle) for the regular cartridges, about 75 ml (2 1/2 syringe bottles) for the high capacity black cartridge.
Step 😎 Insert the needle 1/4 to 1/2 inch (5-10mm) into the fill hole. Be careful not to puncture the bag, especially if you have a sharp needle.
Step 9) Inject the ink into the opening.
Step 10) Tilt the bag so that the opening is at the top. This will let the air bubble up and out.
Step 11) Using the syringe, suction about 1 ml (1/4 teaspoon) of ink and air frothy mixture out of the top of the bag.
Step 12) Inspect the ball. If it has been damaged, you should use a new ball or the damage may cause a slight leak. (We have additional balls for sale.)
Step 13) Replace the ball in the cartridge. Saundra says, "The tip of a retracted ball-point pen is ideal for this."
Step 14) Turn the cartridge upside down (stem down) and gently squeeze to check for leaks.
If you see a leak there are three possible problems.
1. The bag inside the cartridge has bursted or is punctured. There is no fix for this: the cartridge is dead.
2. While refilling you allowed ink to escape and get on the white collar surrounding the exit port, bulb and fill hole. The ink has now leaked between the bag and the sides of the cartridge. Even though this is usually only a small amount of ink it will act like you poured an entire pint in there! The solution is to remove the bag. Please do this over the sink. As you are looking at the cartridge you will notice that the sides are long ovals. Hook your thumbs inside the ovals and pull as if though you are going to pull the cartridge apart. You will see two plastic tabs. Release one and then the other. Using the bulb frame as a gripping point, pull straight up and lift the bag. This will be messy. Rinse the outside of the bag and the inside of the cartridge shell. Try not to get water on the copper chip while you are working. Using an old towel or a paper towel, dry off the bag and dry out the inside of the cartridge.
3. You have not pushed the ball into the hole securely. Push it in again and wipe up the excess ink. Squeeze the cartridge to make sure you have it sealed tightly before putting it back in the printer.
If there are no leaks insert your cartridge into the printer and print.
The light on your printer warning you that the ink is low will remain ON. This is normal. Do not panic: just see if it prints.

I have the same printer and have exactly the problem you described in your post. My problem is, that after I press OK in the boot menu when it shows "set to mfg_mode" it doesn't do anything else than to just jump back to "boot code menu" plus I can't get out of this loop anymore: it is togling between "boot code menu" and "set to mfg_mode" in this mode. How do I get out of the setup menu?

BINGO! Skip the "manufacturing mode" business, and use a small piece of scotch tape!
I found another solution which is to cover the oblong hole on the cartridge with tape and it's now printing again. Takes seconds...
