Digital BW, The Print

I seem to have a pronounced dither banding problem on the 7600, not 
only with QTR but anyway I try it-except in unidirectional mode. 
Seems there's a bi-direction problem of some kind that isn't being 
fixed by simple head alignment. So, a question for Roy, and a 
general question to anyone who can help: 

How do you write in the command for unidirectional printing?

Where can I get the tech/service manual PDFS for that printer?

Thanks
