Hi Terry, you must be in the east, it's spring in the west... :)  I  
haven't run quads for a long while, but when the OEM's are clogged as  
you describe, where some nozzles will check fine, some not, then  
switch around on another test.. I turn the machines off for a few  
hours. Turning them off usually causes a clog, but when the clogs are  
that frustrating and not making sense, leaving the printers off so  
the heads park, seems to settle the inks a bit..

Hope you've already fixed it.

Carolyn
