HP Envy 4512 Scanner not working

[cindialane]

My printer prints fine, but it will not scan.  I am working from an Apple iPhone ( I have an i8plus and i11, but both have same problem.)  I use the HP app.  In the app, my printer says ready, and the green light is on.  It can detect ink levels.  But, when I just want to scan, a wheel just circles and circles, for about 2 minutes, then says printer not ready.  I need to scan.  Please help.

Hi @cindialane,

I'd like to help!

Are you able to make a stand-alone copy using the printer?

If yes, then 

Let's try the below steps to see if that helps -

1.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks!

2.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices is using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

3.) Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it.

4.) Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source.

I'd like to know the following to isolate the issue further-

1.) Are the printer and Mac connected to the same network?

2.) Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual band has different SSIDs for 2.4G and 5G networks.

3.) What is the distance between the router and the printer?

4.)What is the status of the wireless light on the printer, steady or blinking?

Hope this helps! Keep me posted.
