More info?)
I just realized I made an error in the posting below. The HP II
cartridges do not allow you to see the magnetic roller from the bottom
slide, or from any other access hatch.
I have worked with a number of laser printers and photocopiers and some
allow one to see the magnetic roller. The HP Laserjet II cartridge does
not. The only thing that is visible form the slide is the
photosensitive drum. This drum is sensitive to light and handling, and
should not be handled.
Therefore, this method is not going to provide the information I thought
it would. I would suggest that the cartridge be removed and held flat,
be gently rocked and shaken to try to redistribute any toner left, and
then try it again. If it provides a few prints (even light and faded)
and then stops printing again, that would suggest the cartridge has
likely run out of toner. I have seen these very suddenly run out of
toner within one or two prints.
If one still gets no prints, it still could be out of toner, but it
could also be another type of failure.
I apologize for distributing inaccurate information. It was not my intent.
