I used to have one of those a *long* time ago :-) I don'r remember ever
having to clean the corona wire, although I did have to run the cleaning
cycle periodically. In case you don't have the information on the cleaning
cycle, see the reference below (but watch out for wrap in the URL). If the
streak is a black streak, that sounds more like dirty rollers and other
parts in the paper path. The cleaning cycle prints a "cleaning page" and
then uses that page upside-down, as I recall. I don't know why it worked,
but it did take care of black streaks.

Could anyone tell me how to access the corona wire in an HP Laserjet IIIP?
Is it inside the cartridge by any chance? I downloaded what was supposed
to
be a IIIP manual, but it doesn't seem to pertain to what I have. I just
want
to clean it to try to cut down on a streak up the right side of the paper.
