Network Prob;em with printer

[Tom5211]

Hi,

after my printer had worked fine for a couple of days, I now have network problems. The printer is not found by the HP Scan Software, the HP Smart App or PDF-X-Change even though my router shows the printer to be connected to the WLAN.

When I want to reset the WLAN configurations in the printer, I am told that the printer has been set up for my WLAN already. Since the printer cannot be found in the network I can neither print nor scan. Upon restart I get the error message C9.A9.60.0B and am asked to restart the printer.  After restart, the printer finds the network, I can do a scan but then the printer disconnects again when I try additional scans. The problem occurred without any obvious reason. Could the reason be that I tried to scan via PDF-X-Change? There are three version of the printer in the device select list for scanning with PDF-X-Change. I have problems with all three. Can that force the error message in the printer?

Just another comment: PDF-X-Change is not the problem. The HP Scan Software does the first scan alright, and then, when I order the second scan without having closed HP Scan the printer is not found in the network anymore. The blue light on the printer starts blinking. I then manually reconnect the printer under Settings/Network. The blue light stops blinking and is on continuously, but the printer is not found by the HP Scan software. I have to restart the printer. Then I can start another scan. But before the scan is finished to be processed by the HP Scan software, the software claims again that the printer cannot be found in the network, even though the blue light is continuously on. HP Scan does not return the Scan PDF to me even through the scan has run through the printer. Windows 11 also claims that the printer is offline, even though the router sees it inside the WLAN.

I'm also having the C9.A9.60.0B error.  I've made no changes to the printer, network, or settings.  There was a firmware update this weekend.  The error appears randomly and the printer won't restart when holding power.  I have to pull the power cord.  I can get it to print once or twice before the error reappears and I need to restart.  Occasionally, it also has issues with connecting to the network that requires power down and back up again, but holding power will work for that.

Hi @Tom5211,

Welcome to HP Support Community.

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

It sounds like your HP OfficeJet Pro 9120e is experiencing network connectivity issues and potentially some software conflicts. Here’s a detailed troubleshooting guide to help you resolve these problems:

1. Check Printer Connection and Status

• Network Connection: Ensure that the printer is connected to the correct Wi-Fi network. Verify that it’s connected to the same network as your computer.
• Router Issues: Restart your router to clear any network glitches. Also, try restarting your printer to refresh its network connection.

2. Reset Network Settings on Printer

If the printer is showing network issues, it might help to reset its network settings and reconnect to your Wi-Fi:

Access Network Settings:

• On the printer's control panel, go to the Settings or Setup menu.
• Navigate to Network or Wireless Settings.
• Look for Restore Network Settings or Reset Network Configuration and confirm the reset.
• After resetting, follow the on-screen instructions to reconnect your printer to your Wi-Fi network.

3. Check for Firmware Updates

1. Using Printer Control Panel: Check if there is an option for firmware updates directly from the printer’s control panel.
2. Via HP Support:
   • Go to the HP Support website and search for your printer model.
   • Download and install any available firmware updates.

4. Update or Reinstall HP Software

The HP software might need an update or reinstallation:

Uninstall Old Software:

• Go to Settings > Apps on your Windows 11 computer.
• Find HP Smart or any other HP software, select it, and choose Uninstall.
• Visit the HP Support website.
• Download and install the latest version of HP Smart and other relevant drivers.

5. Troubleshoot the Error Code

The error code C9.A9.60.0B might indicate a specific issue. You can try the following:

1. Restart the Printer: Turn off the printer, wait a minute, and turn it back on.

I hope this helps.

Take care and have a good day.

I have tried most of these things on my 9135e and still having issues. Can you post update/reinstall instructions for a Mac, please?

After working with HP support, I was finally able to get a resolution - reset the printer to all factory defaults and reconfigure the Wi-Fi to my network and Firmware Update settings to Auto Update.

Hi,

this comes with a delay because I was away from my printer for a week. I could not repair the network problems by any of the suggested means. Thus I reset the printer to factory settings according to the procedure that has been suggested to me before by Irwin6 and tried to reinstall the printer. Unfortunately, the setup procedure does not complete. It gets stuck in an apparent loop the preparation phase before the alignment page is being printed. I am quite desperate, because now I have the printer in an undefined state and can neither print nor copy nor scan! I also cannot reset anymore!

[Tom5211]

After continuing problems with the network and the computer becoming arrested in setup I contacted the German hotline which guided me through reset and setup. In the end, it seems the solution to the problem was setting the WLAN frequency to 2.5GHz.
