After reviewing your order history, I see you are using the older style refillable carts in your 3880, which were purchased in 2010.
These older style refill carts use large "control" chips attached to two of the carts, and the other seven carts use Epson chips with tape over the 4th chip contact. Which two carts in your set have the large control chips attached?
If two of your carts aren't resetting the ink level after doing the reset procedure, then it could be that the reset function of the control chips is no longer working correctly, or the VM chip is no longer working right, or the tape has come off the chip, or the reset procedure wasn't successful.
I recommend making sure the VM chip is flat/straight on the cart, and the 4th chip contact is covered with tape as per the instructions (but none of the other contacts are covered, and nothing is on the two control chip contacts).
Go thru the reset procedure, making sure the printer LCD panel displays the correct message as per our instructions before moving onto the next step (if you move too fast, the printer can't keep up and the reset won't be successful).
If the VM chip still won't reset, then you could try a new Epson VM chip (cover the 4th contact of the new chip with tape after attaching to the cart).
Otherwise, it may be time to move onto the new model refill carts, which have auto reset chips that lay over an Epson chip on the refill cart, and automatically reset ink levels.
I hope this helps. Please let me know if you have questions or there's anything further I can help you with.
