cartridge errors

[carolstew]

I have a HP 4650 Series printer.  Suddenly I started getting error messages that cartridges are not installed correctly.  I have removed them and reinstalled them and still get the same message. I ran a test on them and test indicated faulty cartridge. 

I even used bottled water and coffee filter to clean cartridges and contacts on cartridge and in cradle area.  instant print said until error is cleared I will not get any cartridges shipped to me.  Thank you
