HP Deskjet printers

[Scott]

Hi, I recently sold a ink cartridge for an old deskjet 660c printer the
cartridge is a 51629A. it was new but I'm not shore if it had passed the
expire date, or if it had one?. Anyway the person that I sold it to has
emailed me and told me that it is not printing text clearly or completely,
but I have no way of checking the cartridge as my deskjet stopped working a
couple of months ago.

When I had my deskjet I think I remember the same thing happening after I
fitted a new black cartridge, because the colour one had also ran out, but
I'm also not shore about that, or why else it could have happened. so could
you please give me some advice on what could have gone wrong?

thank you
Scott

Hi, I was told today that the printer is now working with a different black
cartridge, but he also told me that he does not print in colour. I guess
that means that he does not use a colour cartridge when he prints, and I'm
pretty sure that my deskjet did not print black text properly when the
colour cartridge was empty. so could there be something different with the
cartridge he is now using which allows it to work, or the settings for his
printer?

thank you
Scott
