In this case, I think you've gotten stuck in your own web Nicolaas.

0% full would mean completely empty (or newly installed), so 100% full
would mean the waste ink cartridge/tank was indeed completely filled and
therefore in need of draining or replacement. A lower number would
indicate less than full. In that case, one would expect 32% would
reference the waste ink cartridge/tank was just under 1/3rd filled with
waste ink, leaving approximately 68% empty. I believe the python
squeezed the truth out of this one ;-)

Terminology can be tricky. Epson has at least one printer design that
starts out as the ink cartridge set, but it also contains an empty area
for waste ink which is pumped full as waste ink is extracted from the
head. Rather ironic in a sense, in that the ink is drained out of teh
cartridge, goes through the heads, pumped out during cleaning cycles and
then pumped back into another chamber in the same cartridge.

Overtaken by events, Arthur. See my reply to the OP.

Hi Nicolaas,

After my posting, I did see the considerable additional discussion and
your postings, but had already sent out my post.

Your posts are appreciated (by me, at least ;-))

Well, from 32% a few days ago and a bunch of prints later, it is now
down to 26%. So the percentage seems to indicate capacity left to take
waste ink and not quantity of waste ink stored.

As is depicted on p97, Replacing the Maintenance Cartridge, of the
fine manual.

Maybe you live in Australia and everything is upside down?

I was asking about the computer display of the printer status, not theon
machine display. Neither the on machine display, nor the "fine manual"
explain what the percentages mean.

Do you have to top post? Makes for confusion. And further, you really
do not need to post links to your e-waste project all the time (we seem
them a lot) unless in a sig; which of course should not be top posted.
