Printer is printing only blank pages

[saravogel]

My HP Printer was working just fine. It ran out of ink and I installed a new 138X laserjet cartridge that I had purchased with the computer when I bought it last year. The computer connects with the printer but it only prints blank pages. I have uninstalled the printer, checked the updates for the printer, drivers and computer and everything is current. I have shut the computer and the printer down multiple times. The printer does connect with the computer - it tells me that everything is ok and it shows the ink levels are full but it only prints out blank pages. HELP!

@saravogel, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand your LaserJet Pro MFP 3101sdw is printing only blank pages after installing a new 138X toner cartridge, even though the printer shows full toner levels and is properly connected. Let's walk through some steps to resolve this:

Check the Toner Cartridge Installation

• Power off the printer and unplug it.
• Open the toner access door and carefully remove the 138X cartridge.
• Gently rock the cartridge side to side to evenly distribute the toner.
• Check for any protective seals or tape that may still be on the cartridge (especially the sealing tape over the drum or toner port).
• Reinstall the cartridge securely and close the door.

Print a Printer Status Report

• On the printer control panel, go to Reports > Printer Status Report.
• If this prints correctly, the issue may be with the computer or driver.
• If it’s still blank, the issue is likely hardware or cartridge-related.

Update or Reinstall the Printer Driver

Go to Control Panel > Devices and Printers, right-click your printer, and remove it.

Download and install the latest driver from HP: Official HP® Support

After installation, restart your PC and try printing again.

Test with Another Document or App

• Try printing from Notepad or a simple PDF file.
• If it prints correctly, the issue may be with the specific app or document.

Firmware Update (Optional but Recommended)

• Ensure your printer firmware is up to date: Update the firmware on an HP printer | HP® Support

I hope this helps. 

Take care and have a good day.
