Hi @Ting10,

Welcome to the HP Support Community

I understand you are facing an error in incompatible ink cartridges with your HP envy photo 7155. Not to worry I will help you to get a resolution to resolve the issue.

To assist better

• Is the light blinking on the printer?

While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove the USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle
