HP Printer Blinking Blue: Causes and Solutions

Quick Answer: The blue light on the printer head means your printer has been successfully connected to your wifi network, but the internet connection is unstable, which results in not printing anything from a device over the internet.

I have also faced this issue many times, and without any technician’s help, I resolved it myself. You can also do it easily.

Don’t worry. The solution is so simple. You have to just reboot your printer and router to resolve this.

I have a Brother printer and the toner used to blink yellow whenever there is an error with the Toner. To solve that issue, i used to shake my cartridge and reset the printer to its default.

I have written this article for your complete guidance, detailed solution, and reasons behind this blinking. You will find all the possible reasons and solutions to this issue. So to get to know more, stay tuned.

What does It Mean When Blue Light Flashes On the Printer?

The printer uses different lights to indicate different issues. The reason for flashing blue light means your printer is having issues with the Internet connection. Similarly, the if your HP Printer is blinking orange, that means the problem is related to the cartridge and it should be replaced.

The first reason for the blue light to blink is that the printer is not connected to the wifi network and the second reason might be you’ve changed your Internet Service Provider and your printer cannot connect to the wifi network automatically.

To resolve this problem, I’ve provided every single possible solution for you. If you don’t find any solution after that, then directly concern the helpline.  

Why Is My Wifi Light Blinking Blue On HP Printer

If your printer is blinking blue light, it means that the printer has lost connection with your router and you can’t use the wireless printing until you have reconnected with the internet.

To solve any kind of problem, we must know why it occurred and that’s why I have pointed out all the possible reasons why there is a blue light on the HP printer.

Reason 1: Slow Wifi

slow wifi

Sometimes because of the weather or some other connection issue, you see that your WiFi is too slow. This is when you’ll see that there is a blue light blinking on your printer head.

So, it’s completely clear that you need an active and pretty fast wifi connection to keep your device connected to the printer.

Reason 2: Wireless Network

The problem occurs when trying to connect to a wireless network. When you buy a new printer and try to connect it to your computer, make sure it is not connected to another printer. If your computer is connected to other printers, then the new one will not be able to connect because there is no room left.

In this situation, the printer blinks blue to indicate that it is facing a problem connecting to your laptop. So, to stop the blinking, first, disconnect all the printers and try to connect again.

Reason 3: Wifi Router is Too Far

Where is your Wifi router? Is it too far from your printer and laptop? Remember that when your router is too far, it does not catch the proper Wifi signals because of the frequency.

Therefore, if you move your router too far from the printer the connection will break and the printing process will stop. In this situation, the printer starts blinking with blue light indicating that the connection is being disrupted.

Reason 4: Outdated Firmware

The software that connects the printer and the laptop is called Firmware. Every time, the software is updated, companies make sure to add varieties to them. All of these things are not automatically done.

Updating them manually is what you have to do. It can be difficult to communicate with your latest laptop or PC when the printer’s firmware is outdated. So, another reason for the blinking blue light is to keep using outdated firmware.

If you do not upgrade the software of your printer more often, soon there will be a service call error which will indicate by blinking all light on printer.

Reason 5: Printer Gone Sleep Mode

The latest printers have advanced technology. When you don’t print and the printer isn’t on, it automatically goes to sleep.

It blinks with the blue color of light when you suddenly start printing it. What happens is the printer is not fully switched on after being in sleep mode. Wait till the printer reconnects with your router and the blue light blinking stops.

If you do not want to connect your printer by using the WPS button, it’s time for using the most popular way of connecting a printer. This built-in scanning feature depends on software and it’s very normal to get disconnected. Now let’s see how to reconnect if you’ve got disconnected.

Step 1: Go to Menu

Go to the Printer menu and look for the printer setting.

Step 2: Go to Settings
