Digital BW, The Print

You will probably have to change the dampers, the pieces that run between
the cart an the head, on those colors that are so badly clogged. A 7500
service manual will tell you how to do this. (You can find them at
http://www.nighthawksolutions.com/manuals.htm) They function basically the
same way the sponges do in a cart providing filtration and limiting flow to
the head. A couple of posts on the 9000 list indicated that you could zap an
old clog in a damper by putting it in the microwave for no more than a few
seconds (8-10 sec. Max). This is purely second-hand info - I have never
tried it so caveat emptor - your mileage may vary.

Join the 9000 list. You'll need it. While these are much better built beasts
than the desktop units they still need a lot of finicky EXPENSIVE
maintenance.
