Why don't Hewlett Packard sell replacement printheads for my Photosmart 7510 model C311a?

[Anonymous]

I've got a HP printer that suddenly won't print.  It displayed the bowtie and hexagon symbols (both black inks), so I replaced the cartridges with genuine HP ones, even though they didn't need replacing at all because the cartridges I had in there were full.  Instead of solving the problem, it only made it worse because an error message  appeared saying the "printhead appears to be missing, not detected, or incorrectly installed."  The panel is stuck on this error message and won't go away.  I trawled through HPs online help pages, I've watched countless YouTube videos and followed the procedures for rectifying my Photosmart printer problem and it still won't work.  The error message won't budge.  The last info I read on HPs website said I could replace the printhead, so I trawled through pages and pages of HPs website looking for where they sell printheads for my particular model.  There was nothing, nada, zilch!  So I visited HP community support for help about where on HPs website I can buy a new printhead, and I couldn't find nuffing, so I'm asking HPs experts where I can buy a new printhead for my HP Photosmart 7510, model no. C311a?  And if HP don't sell them, why don't they?  I mean I've got a piece of machinery here that I could repair and HP make it really, really, really, really difficult for me to do it!!!!!!  IIt ain't right  because in certain parts of Africa and India they'd actually repair this printer, so why are HP making it difficult for me to do the same?  Where can I buy a replacement printhead for my Photosmart 7510 (C311a) printer?  And if HP don't stock replacement printheads why don't they?

I still haven't got an answer to my question where, on HP's website, can I buy a printhead for my HP Photosmart 7510 (C311a)?  I want to repair my printer.  It can be repaired.  After applying various troubleshooting procedures that HP recommended I try my HP printer still isn't working.  HP said on their website that if I've exhausted all avenues then try replacing the printhead and gave instructions on how to do so.  HP also said they sell printheads.  I would like to repair my HP printer by replacing the printhead.  I want to buy one a genuine printhead from HP and not some knockoff from some obscure seller on Amazon.  There must be someone from HP who can answer my question.  I look forward to a reply.  Thanks!!!!!!!
