ink in wrong colour order

[shellglen69]

Hello can anyone help me
i have just purchased a cis for the epson dx7400 but when i came to install it i realised the ink is in the wrong order.
my old cartridge has blue pink yellow black and the new system has them in blue yellow pink black can the yellow and pink be swapped round
and if so how. I dont want to try without advice as i may break it.
The company i ordered it from stated on their site it was compatable with my printer.
Maybe someone has a link to a help site.
Thanks
michelle.
