Digital BW, The Print

I've just spent the better part of an hour searching the forum for
information on whether or not using cleaning cartridges is necessary
when switching from UC to UT7 on the 7600 (I just picked up a used one
on ebay :-) happy, happy!). Obviously if I can avoid spending $100+
for a collection of cartridges I will never use again, I'm all for it.

I've come to the conclusion that in the last couple of years there has
been no general agreement on this issue and am wondering what the
current consensus is, or if opinions are still divided.

Any thoughts, advice, etc. welcome, especially considering that aside
from my 1280, I'm entirely new to the realm of the wide printers. 
And, from what I've read so far on this list, they are an altogether
different class of beast.

Thanks in advance,

Eric
