Digital BW, The Print

While experimenting with various mixtures for a new UT-R18, I've had
my 1280 (which I wrote off due to a clogged head) sitting with
cleaning carts installed.  I've run a couple of pages of purge
patterns every night for about two weeks and the heads are now
unclogged and giving a perfect nozzle test pattern again.  It's made
me think back as to which printer required less maintenance: the 1800
or 1280 with pigment inks.  My memory says there was not much
difference maintenance-wise, and the 1280 did a real nice job with
it's 3.5(?) picoliter drops.  It a whole lot slower than the 1800, but
it has a paper thickness adjustment which the 1800 does not.

I'm assuming the 1280 would require LK inks for smooth midtones
because of the dot size, and, if I remember, Eboni diluted tends to go
rather warm.  Is this correct?  If so, then the 1280 would use a wide
format ink set as compared to a 1.5 picoliter inkset.

Am I crazy to consider using the 1280 as my B&W printer and leaving
the 1800 for color?  You have my permission to say so it I am!
