HP ENVY Photo 7830 printer - blue screen error B8494646

HP Recommended
HP ENVY Photo 7830

Our HP ENVY Photo 7830 has stopped responding to print actions. 

When documents are sent to print wirelessly the printer’s touch screen goes blue (which disappointingly seems like a common problem with HP printers) and the error code B8494646 is displayed.


I have tried the usual recommendations - restarting our wireless router, restarting the printer (pulling power cord out whilst printer is on, waiting 60s, plugging back in), removing the cartridges and restarting etc. Nothing has worked, we are unable to print anything.


Very disappointed as the printer isn’t even a year old and it’s a necessity for our work.


Are there any solutions that actually remedy the issue? It is still in warranty, so is a replacement possible?
