So, the problem is "ink-to-ink" more than anything?

<frown> I'd just *not* like to have to go to the trouble of
reprinting these things because I was foolish in how I
*stored* them! :<

OK. So stick with that, in general (and, presumably, the 8200

I've come across several 840's with the *ink* covers broken
off at the "hinge" (plastic is *such* a double-edged sword
when it comes to pros-cons)

Oooo! When a head fails, I assume an element just doesn't
heat up (so you lose that strip of the page)? Or, do I
have to worry about magic smoke and things catching fire??

OK, so steal the power supplies!

So, the fact that it uses less ink suggests it was just a
firmware issue? I.e., there is nothing about the 840 head
(or mechanism) that required it to be more wasteful?

<frown> These things are *big*! We don't have basements here.
And, it's way too hot in the garage to store this sort of stuff
(I'd wager the ink itself would melt if left in the printer!
Let alone the accelerated component mortality). Since they are
so *heavy*, you can't even STACK them someplace out of the way...

Yes, but 5si toner is more expensive! :> (I can "rescue"
toner cartridges from 4's quite often which keeps the cost
of ownership really low :> )

Yeah, that would be nice! I've retired my plotters despite the
fact that reducing C & D prints to A/B is really hard on the eyes!
But, I have an Epson SP2000 and an SC3000 which are both capable
of wide (e.g., 17") printing -- though being color means they
tend to be slower than monochrome printers and, being ink jets,
tend to be FAR slower than lasers!
<shrug> Thankfully, printing schematics (and PCB artwork)
is something that isn't done in the same volumes as manuals, etc.
[As an aside: Adobe Acrobat/Reader/whatevertheyarecallingitnow
will not let you import a document wider than ~16",IIRC. Since
B size drawings are 17" wide, you're screwed! (I have been
scanning all my drawings and storing them as PDF's) *But*,
if you import the drawing as 11" wide (by 17" *long* -- i.e.,
rotated!), it will not complain. Once you have imported it,
you can then rotate it to the "correct" orientation. <grin> ]

They are almost as much fun to watch as plotters. Since I
work with "mechanisms" a lot, I enjoy seeing more than just
"blinkenlights". And, of course, wondering how and why they
are doing each of the little things they do in the process
of performing their overall task... (e.g., the little
dance that inkjet printers do to clear the heads)
