Converting a 7900 to PiezoDN

#1

Hi all, a friend of mine is offering to buy a 7900 from him. Printer has two non working channels.
I’m interested but afraid of starting up a long and winding road going through assigning channels and such.
How difficult is this to make it work ?
Point is I’d like to make some 24 in wide negs !
Of course I’ll have to get new rechargeable ink carts, more ink and all… Most thing I feel scary about the 7900 is that of assigning channels. I’ve heard this can be done but I never even had the chance to see.
Any tips will be strongly appreciated.
On the other hand I know the machine needs cleaning, maybe a good cleaning with Piezo Flush would help getting all of channels back on. Still my friend is buying a brand new and giving this away. Well, this he’s doing in a trade with some US dollars.
Thank you
Pablo

If you have PPEv2 it’s this easy:

Or you can do it the free way:

Hola Walker, was expecting you, who else … !
Well, bad news is I have PZK7 SEL inks. No PPEv2 down here.
So… any directions on my ink set or is that only PPEv2 possible ?
Thanks

PPEv2 is just software. It works equally well at remapping K6, P2, K7 curve as it does Pro curves (or PiezoDN curves). But yeah, second link is the freebie.
