E7 error even when filled with ink

[tscottbarsouth]

My printer is showing the E7 error code for out of ink and indicating it is the “k” ink for black ink. The printer is full of ink and was powered on and off with everything in place and still showing this message. How do I proceed/is there a way to reset this? Had issues with this printer showing low ink for the black ink as well prior even tho the ink is full.

Hi @tscottbarsouth,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Smart Tank 7301 All-In-One. Not to worry I will help you to get a resolution to resolve the issue.

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 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 warm-up period finishes and the printer is idle
