HP Laserjet 5 horizontal stripes

Hi everyone,
I`ve had a HP Laserjet 5 printer for a while, and about 300 pages ago I put
in a new toner. Suddenly today it has started laying down horizontal black
lines, about 5mm in width, repeated every 9cm. Nothing has changed with the
printer, it`s not been moved or knocked. As it started the lastest print
job, which has these lines on, it started squaking rythmically as it was
bringing the paper through.

I`ve tried turning it off and on and swearing at it, as well as removing the
toner cartridge and reseating. Any other ideas that might help, suggestions
on a repair etc?

All help will be greatfully received!

Start a print, then switch off the printer while it's printing. Take
out the cartridge, lift the flap, and rotate the drum. If you can see
the black line(s) on the drum, that's the problem.

First thing to try is another toner cartridge.

No missing cogs at all. Replaced the toner cart and it is now working fine.
All I can assume is a dodgy toner :-)
