Ink errors and "No entry" sign on HP 6950 printer

HP Officejet 6950
Microsoft Windows 10 (64-bit)

After changing an ink cartridge, it showed Low very quickly (even though it is genuine HP from Viking who is usual supplier for years. Then others said they were low, and despite changing immediately says it is low !

 

After changing another ink,  the printer displayed that there was a fault and no ink had been installed at all. Every ccartridge has a "No entry" sign on it in the ink display window - even though they are all present and have varying levels of ink. The printer has been switched off and back on again to no avail.

 

I think I had the printer about a year.

Clean the electrical contacts

  1. Open the door to access to the ink cartridges.

  2. Wait until the carriage stops moving before you continue.

  3. Push the tab on the ink cartridge indicated by the error message, and then pull the ink cartridge from its slot.

       CAUTION: 

    Clean the ink cartridges one at a time. Do not leave an ink cartridge outside of the printer for more than 30 minutes.
