Thanks for that snappy tip Taliesyn! I'll just sculpt a bit of commentary on duplex printing. We just ran some impromptu tests to compare the duplex feature with regular printing. As I had been using duplex regularly, naturally my curiosity was piqued. Being a businesswoman I'm not one to wait for jobs to print out. I have a tight schedule. With the help of my son and a kitchen timer we ran off some full page documents. Low and Behold we discovered that it's so much more efficient (faster) printing one side
of the documents and turning them over by hand to do the reverse. My official timekeeping son reported I could cut printing time in half. I'll
have to hire him now. And as you stated, the text was also much better -
darker. I used to think there was something wrong with my printer because
I'd notice the lighter printing of duplex compared to regular printing. I'd
even do head cleans. Now I find I was just wasting ink - color ink, I'm assuming because it's not really black. Goodbye duplex! No more watching
and waiting for the "paint to peel".


As I have that printer, thanks for the interesting info./test! Where did you(all) find which black tank was used for manual vs. auto. duplex printing?

I had once upon a time tried duplex when I first got my iP5000. I thought it was a nifty trick how it flipped sides automatically. But I left it at that.

Soon after, someone noticed there was a difference in the darkness
between the two methods, plus the fact that it took much longer to print. Which resulted in some of us - like me - to run a few
tests. What I found I didn't like. Dye ink (a mixture of the other
colors) was being used to make black. This is a waste of precious colour
ink when there is a cartridge in the printer specifically for this
purpose! Forcing the other colors (plus the dye black) do this job will
naturally be slower (less ink nozzles) and will result in something
approaching black - more like fuzzy dark grey - and a finished product
that will take much much longer to print because the printer fiddles with the page/s (in out, in out, stop, start), and will not be in the
near waterproof black which comes only from the large ink tank and will
not nearly resemble the near laser-like sharpness which can only come from the pigmented black. Pigmented ink doesn't soak into the paper anywhere as much as dye inks, hence it's sharper. This is easily visible
with the naked eye and quite shocking with a magnifier.
