Printer wifi issues and lights blinking

[George750]

Hi, i was feeling comfortable using printer form HP since those issues. Before some days printer didn't worked as normal. Lights blinking and nothing happen. After a restart, everything goes as normally.

The next time printer lost the wifi because it was many hours turned on.

Now facing again wifi probelm and i cant turn it on even printer restarted or unplug it for 1 minute.

The first time (when i bought it) the on/off button did not react. I had to push it many times to turn off the printer and some times to turn on.

What are all those problems with this new HP printer. I am pissed off and cant continue my work.

HP is one of the oldest printer manufacturers. Why this issues and a new technological device??

I made my choice to HP and o abandoned Canon printers i used to have for many many years.

Anyway, how to fix this? Is there a software update or something? Its not easy for me to take it back to store because i bought it online and its far a way from me.

I have got some videos to show you to see what is the problem.

Thanks

George

Hi @George750,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue with your HP Smart Tank 750 All-in-One printer, it seems there may be both hardware and software issues at play.

Let’s go over a few troubleshooting steps to help you get things sorted:
 

1. Wi-Fi Connection Loss

If your printer is losing Wi-Fi connection after being idle for several hours, this may be due to power-saving features or unstable Wi-Fi.

Check Printer's Sleep Settings: Go to the printer's control panel or the HP Smart app to ensure that sleep mode or power-saving mode isn’t affecting the Wi-Fi connection.

Update the Printer Firmware: Update the firmware on an HP printer

• Download the latest firmware update from the HP Support website.
• After updating, restart both the printer and router.

Static IP Address: Sometimes, assigning a static IP to your printer prevents it from disconnecting.

• Log in to your router settings.
• Assign a static IP to the printer based on the printer’s MAC address.

2. Unresponsive Power Button

This issue can be hardware-related or possibly a bug in the firmware.

• Firmware Update: The latest firmware updates often resolve unresponsive power button issues.
• Power Cycle: Try holding the power button for at least 10-15 seconds to force a shutdown.
• Electrical Reset: Unplug the printer from power for at least 5 minutes (instead of just 1 minute). Then plug it back in and try turning it on again.

3. Perform a Printer Reset

Performing a full reset can sometimes resolve weird behaviors with the lights blinking and buttons not responding:

1. Turn the printer off and unplug it from the wall outlet.
2. Wait for 10 minutes.
3. Plug it back in, and turn the printer on.

4. HP Print and Scan Doctor HP Print and Scan Doctor

You can run the HP Print and Scan Doctor software to diagnose and automatically fix connection issues. Download it from here.

5. Check for Software Updates

• Ensure your HP Smart app and printer drivers are up-to-date by checking the HP Support website.
• Sometimes, a driver mismatch or outdated software can cause connection issues and unresponsive buttons.

Hi and thanks for your support on this. unfortunately  non of those helped. WiFi not turning on anymore. Speaking on phone with support, a technician did all the necessary tests but the problems did not solved so they will take the printer for service and i will have a replacement.

I hope not have anymore issues. Its a very good printer and want to continue do my business with this one.

Thanks
