My HP Laserjet 1000 printer has started showing short horizontal lines
(about 3/8 inch wide) down the middle of the page. The lines are about 1.5
inches apart which suggests something about 0.477 inches in diameter is
laying them down. I can't see anything inside the printer paper path nor
can I see anything in the cartridge that would do this. I haven't torn down
the printer other than opening the back door and also removing the cartridge
to look inside.
I'm looking for ideas. The HP web site and the printer manual are no help.

Thanks, I just did. I realized I was sort of OT right after I hit the Send
button.

If the line is a "gap", in that there is clear pattern to
it, there is no image (or text) data missing from the page,
it's probably a dirty or worn rollers and cleaning the
printer and/or replacing the rollers might help. Could
instead be a worn gear, if you can see the gears and/or note
any play in a partiuclar spot, that's obvious enough.


If the line is in fact data missing from the image, you
might have a bad spot on the drum. From your description
this seems less likely but you can remove the cartridge and
there is probably some release level you can hold in to free
up the drum and rotate it while inspecting it for flaws.

Thanks, Kony. I'll delve further.
