Product: HP OfficeJet 6958
My printer won’t work, when I first plugged it would just keep starting up over and over again, now its just blinking saying ERROR CODE 0XC9C70000, then at the bottom it says HW_GAUSS_CHIP. It won’t even turn off when I press the power button. I’ve tried plugging and unplugging it and taking out the power cord in the back, I don’t know what else to do.

Hello,
I think its a printer hardware failure, and printer need to be either replaced or serviced.
However you may try the below steps..
- While the printer is ON, unplug the power cord from back of the printer.
- Also unplug other cords like USB , Ethernet or FAX cord from back of the printer.
- Now power off the wireless router.
- Wait for 60 seconds.
- Plug in the power cord directly to wall outlet ( bypass the surge protector / power strip ) and then to the back of the printer.
- If printer does not power on automatically then press the ON button to do so.
- If issue still persists, its time to get the printer replaced if in warranty, or service the printer or go for a new one.
