    During the latest years my (rare) home prints had become gradually "light" and I assumed that this depended on the toner cartridge, which actually was very old (2008). So I didn't bother and planned to wait for the toner to run out completely.
    Two weeks ago, when ordering a toner cartridge for another printer we have, I decided to order also an original 15X cartridge for the HP1200.
    When it arrived I immediately installed it and, as a quick test, I printed a couple of pages which looked OK. Days later, when I tried to print a 20 page document, I had the following surprise:
    starting from the third/fourth page the prints became gradually... lighter and within another ten pages they were almost illegible.
    The printer behave regularly, with no signs of errors or malfunctions.
    From then onwards I was never able to obtain a readable print again. If I launch the self test print I get always (with no worsening) a very faint heading while all the rest is barely perceivable.

    The new cartridge was a sealed genuine HP. I had to remove the toner safety stripe by breaking the side little plastic lever.
    Sadly I can't plug in the old cartridge any more because I returned it for recycling.

    It really seems to me very unlikely that a new and original cartridge could be empty (!), so I don't like the idea of buying another one just to test. I also dislike, however, to dump the printer altogether.
    I think I have some "fixing" skills and so I'd like trying some further investigation, if only to understand what is the cause of this unexpected problem.
    Any suggestions?
