HP Model 7310 Officejet Printer won't come on.

[Kenyarber]

Printer turned off; can't get it back on by pushing the ON button. I checked all the electrical connections are OK. This problem started just after I replaced HP Ink Cartridge 95 tricolor. ON light indicator will not come on. Is there a hidden fuse or interlock switched I'm missing?  Any advice would be useful. Thanks, Ken Yarber

Thanks for joining the HP Forums @Kenyarber, 

I understand your Officejet 7310 will no longer turn on and the 'On' indicator light will not illuminate either. 

Let's perform a hard reset. To do so, leave the printer on and unplug the power cable for 1 minute. While it is unplugged, hold down the power button on the printer for 10-15 seconds to release any built up power, then after the minute has passed, plug the printer back in. Also, even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause.   Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector

Changing the power source (ac wall outlet) to my HP 7310 solved the problem. Apparently one of the receptacles on the power surge bar is defective.  Thanks for the advice. Ken

I have a 7310 ll in one and it will no longer turn on. I have removed and reconnected all the cables to a wall power source. I have checked and replaced the fuse in the plug. What else can I try?

Thanks for your help

Very unlikely  installing the ink cartridge has caused this error. There must be an issue internally with printer
