I have a Sharp Z50 and a Sharp Z20 personal copy machine. The little ones
where the top moves back and forth. They both have the same problem of
printing out portions of the page with big black bands. Sometimes the
whole
page is black.

I don't want to spring for new parts until I know what is wrong. The parts
are very expensive. Can someone guide me to a place where the basics of
these types of small copiers are covered?
