Digital BW, The Print

Just did my first UT2 printing on 1280, using epson black because MIS 
sent me eboni cart for the wrong printer.  Results so far are 
exceptional.  However I do need to learn how to utilize curves so I 
achieve WYSIWYG.

Am wondering if I can switch back and forth between EP color cart and 
MIS UT2 without special precautions to prevent dryout or clogging?

Thanks for any help.

Epson's own 1280 cartridges for the 1280 don't self seal, do they?

Anyway, check out the MIS web site. Here's what they say about self sealing (in their 
their FAQ's nicely illustrated description of the Epson poppet-valve cartridge):

"None of the clone cartridges on the market have these poppet valves.  We don't think 
they have figured out how to insert the spring and the poppet valve while the 
cartridge is being injection molded.  It is a good manufacturing trick.  We do not 
know how they do it either."

I put scotch tape over the holes on the bottom and top.  However 
they do leak since there is no valve inside.  It is messy actually.  
Which makes me wonder; why do they not leak when in the printer?

All the recent Epson carts have a 'poppet valve' in them that seals 
them off; Oddly enough, the ultra-cheap Chinese dye inks that MIS 
has a $5 sale on, also has them, suggesting they come from the same 
factory? At any rate, they're handy gadgets, because they make 
vacuum-refillng easy if you're going to keep using dye inks. I found 
that if I tape the vent holes shut (after I've sucked out as much 
ink as possible with them open) and create a vacuum with a syringe, 
the valves keep the vacuum when I pull away the syringe. I then 
apply a loaded syringe to the chamber, and the vacuum sucks in the 
ink. Takes a little parctice to get the right vacuum, etc., but it's 
worth the effort!

Hmm, I hadn't realized that--I had mistakenly assumed that the poppet feature 
started with the models having individual color cartridges.

Thanks for mentioning these; that makes the MIS web site statement (about no 
poppet valves in "clone cartridges") rather out-of-date. I guess the speculation might 
be that these aren't really "clone" cartridges--perhaps they fell off the back of a 
(Chinese) truck? 
;-)
