@GOINDA, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The E7 error on HP Smart Tank printers typically indicates a low ink or out of ink. 

Try the following steps to resolve the issue:

1. Power Reset the Printer

• With the printer turned on, unplug the power cord from the back of the printer.
• Also unplug it from the wall outlet.
• Wait for 2–3 minutes.
• Press and hold the Power button on the printer for 30 seconds to discharge any residual power.
• Plug the power cord directly into a wall outlet (avoid surge protectors).
• Reconnect the power to the printer and turn it on.

2. Check Ink Levels Visually

• Open the ink tank lid and verify that all tanks are filled to the correct level.
• If the black ink tank is full but still shows an error, proceed to the next step.

3. Clean the Ink Sensor

• Open the ink tank area and gently clean around the ink sensor using a lint-free cloth.
• Look for any dried ink or dust that might be blocking the sensor.

4. Update Printer Firmware

• Visit the HP Software and Driver Downloads page and enter your printer model.
• Download and install the latest firmware for your printer.
• Alternatively, you can update via the HP Smart App.

5. Perform a Test Print

• After restarting and updating, try printing a test page to check if the error persists.
