Digital BW, The Print

My 7000 seems to have developed a problem clog (PiezoTone Selenium) 
while lying fallow in August while I was off doing other things.

Regular cleaning cycle actually made things worse (mostly the yellow 
position). Down loaded some instructions on doing KK2 cleaning, but 
cannot find "Check Cleaning" option as described in those 
instructions.

Anyone able to take me through the step-by-step? The service manual 
doesn't offer much help.

Also, any equivalent of the desktop printer's Windex soaked paper 
towel under the head routine? Or any other helpful hints?
