Digital BW, The Print

Hi Jerry,

I'm sorry, I don't think I was aware that you had not managed to get _any_
printing again off those carts - but I can't double-check the emails you
sent me as they were recently casualties of a late spring-clean of my email
software. I do recall that you decided to take a break from BW, but I don't
recall why exactly.

My own experience with carts has been rather limited, I saw enough after the
first two sets to get the CIS thing going - though I realise this is not
necessarily an option for some people. I think that the way people perceive
problems with Piezo has changed dramatically over the last few months, and I
will act now to ensure, for example, that my stock of carts is wherever
possible stored 'right way up' and packed in such a way to make it a little
more likely that they will not be upside-down for too long during postage
(of course, this would be rather difficult to guarantee).

From the way you describe things now, I would be inclined to suspect that
you were experiencing a settling problem - yes, that means I think (whatever
the rights-and-wrongs of it) the ink is viscous enough that simply having it
the right way up does not mean the ink goes to the right place quickly!  For
comparison purposes... the ONLY time I personally have experienced problems
with the Piezo Color carts on my 1160 was one day when I was in a rush and I
installed a cart that had been wrong-way up in stock. It took a day to
clear, some effort at first, and when that didn't pay off I just left it,
and that cleared it - though of course I swore a bit in the meantime. Every
single cart installed since then has been fine; though I am not a msssive
high volume user.

I will contact you off-list to discuss options...

Best regards,

Nij
