Digital BW, The Print

John:
Having done a few head replacements, the physical part of putting in the new head doesn't 
take over 15 minutes. But the really tough part is the new head alignment!

Recommend you have some narrow 8" wide roll paper or long scrap 8" wide by about 3 
feet. to print out alignment patterns.

The initial fill is vital to flush out the new heads and get a good head check.

Follow the sequence of alignment steps in the service menue. Don't stop in the middle!
Then don't forget to also do the regular alignment tests also. I had never had to do that 
one again, but the last head I replaced, it was all screwed up--printing offset images.
