QTR-Quadtone RIP

I solved my problem of wachy highlights.  The problem was with the magenta cart supplied 
with my CIS.  
Continued head checks showed no ink pattern where the magenta ink ought to have 
appeared.  Yes, the Epson magents cart worked just fine, thank-you.  
Removing the cart, testing and working the valve inside produced a proper ink flow.
Re-installing the cart, running a head clean and then a head check gave me a proper 
printout.

This is not the first time I've had trouble with a generic cart!  The first time I thought I had a 
plugged print head.  Many dollars later, the technician saisd the head was fine,  it was the 
crummy #rd party inks causing the trouble.  Be warned, if you do have trouble with a CIS 
(B+W Color), QuadQTR, etc.  it may not be a plugged printhead but only a sticky valve in a 
cartridge.
Good-night and God bless.
