Refilling HP Designjet 3000cp tanks?

Anyone tried refilling the HP Designjet 3000cp tanks? Same as the
2000cp, 2500cp, 2800cp, 3500cp, and 3800cp.

I just bought one (used, of course) and it's just out of yellow ink. I
don't immediately have the money for a set of new cartridge/tank sets,
and the other colors are about half full. And I have some yellow dye
ink that was for an Encad Novajet Pro 36, which uses HP bubblejet
heads. I know it won't be quite the right shade, but I'd like to be
able to print some non-critical stuff to raise money towards buying a
set of the UV inksets.

So- has anyone tried refilling these CP series tanks? Any caveats?

Thanks,
Steve Greenfield

 

While I don't know very much about HP printers, I'm pretty sure we
don't ever use the term bubblejet

WRT putting ink from another type of printer - even one that has HP
technology in it, I would be concered that the formulation of the ink
for the one was not compatible with the other. As time has passed,
nozzles have gotten smaller. Older ink might not flow very well
through newer nozzles.

I'd be more concerned if it was pigmented ink, less so with dye ink.

I forgot that HP calls it (I think) thermal inkjet? Is that right? The
Encads I got that included the ink have 300dpi HP heads, however the
same ink is sold to be used in later Encads that are 600dpi and may
even use the same print heads as the HP 3000cp, now that I think of it.

I also have some dye ink I pulled out of 3rd party Epson 3000 tanks
(don't cringe yet) that I've been using in a Canon BJC 6000 (now that
one does go by "bubblejet").

The HP 3000cp tank looks simple enough to refill, the toughest part is
going to be pushing in the spring loaded ball bearing while injecting
ink in. It's not my intention to futz around with this in the future,
the idea is to start printing now to raise the money to buy HP OEM
C189xA UV cartridges. I'm thinking I should empty the yellow
park/cleaning thingie if I'm going to refill the yellow.

I was hoping to find someone else who'd actually tried it. It is worth
a try, as long as I empty the yellow waste tank the worst I can do is
clog a head that will be replaced anyway.
