Jim,

Hang in there I am using this set in my 7000 and they are the most
beautiful monochrome inks I've ever seen in every regard. They turn
this old workhorse into something really fantastic, and I've tried
them all. And, these don't clog.

When I first loaded K6 I had the problem a number of folks had with
the Magenta cart having the wrong dilution in it. The old lot number
had a serial number like - NEU-109-060-M, that is wrong, if you have
that lot number call them and they will send you the correct Magenta
dilution. They were misfilled at the factory I belive. The problem was
in the ability to use the same carts in different machines or
whatever. For all future shipments they will make these carts only fit
the correct slot in the K6 configuration.

The correct M cart should read - NEU-109-100-M. If you have this M you
are ok in that regard.

I also had some confusion about which slot to put these things in
since they would fit many machines and the color coding can be
confusing if you are not paying attention. But, the info on their
website has always been correct.

Check you configuration. For the 7000 it should read:

Black Slot - shade 1
Cyan Slot-shade 2
Magenta Slot- shade 5
Light Cyan Slot - shade 3
Light Magent Slot - shade 6
Yellow Slot - Shade 4

Now if all this is set correctly and you are SURE that all of your
lines and heads have enought PURE ink in them, after the initial fill
to function properly then you might want to look at your curves.

You might try one thing before you do a custom linearization with QTR
ICC create. Try printing using the K6 Raw curve settting instead of a
premade paper curve.This prints a "non-linearized" output from QTR.
Also remember with this QTR configuration you need to use Photo Matte
paper as the greyscale output profile, not GG 2.2 as with other inksets.

Now that I have mine working with custom curves made for QTR I've
never seen anything so nice and easy. Great blacks, fantastic high
values and very smooth midtones, always perfect print color. I want a
bigger printer to put them in.
