wrong head

Did you enter the head rank? (white sticker on the front of the head)

Yes, I enter the head rank, it´s posible that the firmware (3.30) recognize non original head?, any solution? thanks

Where did you get the print head from? You don't want to buy from just any where. We have brand new print head from Roland sealed in box for $800 plus shipping.

I buy the head an a local store, and he say it´s posible roland recognize non original head whit the last firmware?? it´s this true??

May be. I've never seen those message on the SP-540V. And we've used all kind of printheads. Try to get the machine to an older firmware version. I don't know how/if VPs can be downgraded.

Head rank

Try putting in the head rank off the old head, may do the trick. Part of the head rank is a serial number which may be the problem. Sounds like just another attempt by a printer manufacturer to lock you into expensive OEM parts.
