  It would be odd if you happened to have two "outliers."

  I've seem one XP v. 98 comparison, and they were very close.

  Be sure to give your black ink the "sniff test."  It should smell just like
  Piezo ink.  If it has almost no smell, then it's the wrong black and could
  well be the problem.

  I've been wondering about ink inconsistencies.  I use my "Color test" curve
  with the 21-step test file to check for major differences in the midtones.
  So, far, (except for the Piezo in CIS v. filled cart) I have not seen major
  differences.  I see only about the same variances that I see with my printer
  anyway.  That is, I see about + or - 1% variances, even with the black inks
  from a single source.

Then for sake of completeness I swapped the CIS's from my Piezo 1160s and
tried MIS on the previously Piezo printer . Suddenly everything worked
perfectly and I have just printed out four excellent MIS VM prints which I
will post on to Tim.

I am not sure what the problem has been as I have never really been happy
with the MIS VM output. I persevered because so many others liked it and I
always thought that I must be out of step somewhere. Windows XP does seem to
make a difference as both printers printed VM poorly under XP, yet one
printer did almost as bad under 98SE whereas the other has now done so well.
I wonder if all that plugging and unplugging of the CIS did something.

I am not going to try to isolate the cause I am just grateful to be able to
print VM well. Can I offer you a public apology for doubting your VM
solution. Additionally I have now networked the two machines and put all my
scanners on the 98SE which means that I can now print, Photoshop or scan at
the same time. I'm very happy.

  Adrian,

  Could bpeteb's posting about seating of CIS cartridges and direct connection
  be the cause of your problems? It seems possible that mere disconnection and
  reconnection has solved it, rather than it being due to a different printer
  or operating system.

  Bob Frost.

  Part of bpeteb's posting:

  "Apparently the inconsistencies may have been caused by the CIS
  cartridges slowly unseating themselves which allows air to enter
  through the base feeds of the ink stems which the cartridges rest on.
  Manny from IJM called me to give me the heads up on a fix which is
  curing quite a few users. You push the CIS carts down and make certain
  that you push them down frequently.

  I had the DDS syndrom which is when your prints lose density in the 3/4
  tones. That is the ink which is mostly affected by the cart rising. But
  Manny suggested a fix earlier which was to bypass the CIS cartridges
  completely and run the tubing directly onto the ink stems. That was an
  instant cure and I am still using that after about 3 months and have no
  plans to return to the CIS system."
