Digital BW, The Print

Hi John,

I wondered what happened with your 7000 after working on the broken 
CN24 -- I assume you got that restored OK, but still no output, eh?

My suggestion regarding replacement of the main board is just to be 
sure it is really necessary before you jump in. Swapping the board is 
sometimes easier and faster than component level repair, but since 
your problem is currently with getting the pump motor working, I'd 
want to make sure that the fault is actually on the main board and 
not with the connectors, cables or pump motor itself.

The manual gives a pretty good description of what is required to 
swap the main board, and as you will see from the procedures outlined 
you're in for a bit of work. It's really not as bad as it sounds, but 
I'd make sure you're comfortable with all the technical steps and 
that the main board is actually the culprit before proceeding. Can 
you get a scope on it to make sure?

I run Piezotones (WN) in my 7000 and they're great -- the new inks 
sound even more nicer!

Ciao,
Richard
