Hey!
The fault code means:
91,523 Left Jetstack Heater is too hot.
I do not know how far you wish to go but I would suggest you have a look at the Printhead wiring harness connectors to see if the connectors are undamaged and on place.
Best Regards
Kimzi

My printer was powered off and when I turn it back on, it goes in circles to power on and then off, on and off, forever (2 hours). I was frustrated and tried to call the tech support, only to get a suggestion to have an on-site service which may end up costing a lot.
I unplugged it from the wall and plug it back in and an error message finally appeared:
Printer error: 91,523.00:1968
What should I do?
