Hp printer mechanical problems and solutions

[mditlove]

HP Photosmart b8850 problem, ink light flashes and printer will not work even though a new cartridge has been installed, tested with several new cartridges at considerable expense to make sure the cartridges were not the problem. Is there a way to replace the ink sensor, HP refuses to fix this or any of their printers and they can't replace it since they no longer make it.

Thank you,

There is no ink sensor; the printer keeps track of the picoliters (really!) of ink used, and when it reaches a certain amount it is considered empty. The printer can read a serial number from the cartridge so that is knows if you just remove and replace the same cartridge.

You should first try cleaning the contacts in the printer where the cartridge is installed. Use a cotton swab with distilled water and let it dry before retying a cartridge. If it still does not work you have an electronic problem and it is likely time to replace the printer.

Thanks, but I have removed cartridges and replaced empty ones by mistake and the printer thought the cartridge was full and printed with bad streaks, so maybe the printer is defective, however, it is only three months old after being replaced 6 times by HP, they now refuse to deal with it because it is discontinued and they've used up their warranty with the replacements, surely there must be a way to fix this issue?

I have also cleaned the contacts both with distilled water and later with a soft rubber eraser which is usually preferable to water when there is an oxide on contacts, all to no avail, what is confusing is that although the cartridges are full, different lights keep coming up flashing, does that suggest anything?
