Hi, i’ve a 7900 with the yellow cart out of ink for months. I started to have some times and ordered a new original Epson yellow cart on my recent trip to Hong Kong (my country just do not have the cart in ready stock, back order takes month).
I opened up the cart and install into the printer, now it read “Ink Cart Error, please install the correct cart”, I did this a few times yet this error didn’t go away. I started to get anxious and re-read the whole packaging to make sure I got the correct cart, it is the Epson T5964 (Yellow 350ml), however, due to I bought this in Hong Kong, the model of the Epson 7900 is being sold in Hong Kong as Epson 7910. The cart happen to be in the same model number so I am not sure if it is the cart sold in Hong Kong for Epson 7910 won’t work in Epson 7900.
Anything I could do, as the cart costs dearly and I want to make sure I can use it, any advise will be much appreciated.
