E9 showing on Printer/ WPS not being accepted

[CMarch5]

Hi there! I have 2 problems. The printer wasn't printing and continually said it was offline. This happens a lot. So I did my usual of uninstalling and tried to reinstall that the Whatsapp tech team advised before. But now the WPS number isnt being accepted and I cant reinstall.  Even the wifi only shows up and isnt connecting permanently now, only when I press the button at the back. 

Second problem is the printer is flashing E9 which appears to mean a cartridge problem. I have enough ink in them, have taken them  out checked no odd bits of paper is in them, all fine. But still flashing E9. 

Any help much appreciated.
