Chip problem frequency seems to be increasing.  I don't know why.  Of the
2000P chips I received from MIS, I think they were all good.  Telling one
chip type from another seems to be impossible without checking them in
either a printer or equivalent.  If someone along the supply chain has
mislabeled or mix chips, it's going to be a mess.  Keep and label accurately
those that work, and have a re-setter.

I did not have that experience with the 2000P that was loaned to me.  It was
really a nice printer.  I used mostly pre-loaded UT-FS carts from MIS.  They
were the old style carts.  Are what you're receiving the old ones or the new
spongeless carts?


Overall, I thought the 2000P made an excellent matte paper printer with
UT-FS.  I don't know how old or used the one I tried was.  If a 2000P has
high mileage on it, the MIS inks might have trouble.  

I'm trying a cleaning solution on a high mileage 7600 before I resort to
changing the dampers.  The lower viscosity cleaning fluid easily passed
through the screens that would not pass UT inks efficiently.  I speculate
that the screens slowly build up layers of pigs -- OEM or whatever -- and
some fluids can get through easier than others.  Viscosity is probably one
factor, and there are no doubt others.  I'm going to see if a few weeks of
exposure to the cleaning fluid will break enough off the screens to solve
the problem.
