My printer is stuck in Validating please wait while we check the cartridges - I've done all of the troubleshooting steps below and it still is stuck in validating. 

If your HP OfficeJet Pro 8025e printer is stuck on "validating" after replacing the black cartridge, there are several steps you can take to try and resolve the issue.

• Wait Patiently: Sometimes, the printer can take a few minutes to validate the new cartridge. It's possible that it's just performing an extended validation process. Give it some time, and see if it eventually completes the validation.
• Check for Error Messages: Look for any error messages or codes on the printer's display screen. This can provide clues about what might be causing the issue.
• Ensure Proper Installation: Make sure the black cartridge is installed correctly. Open the printer cover, remove the cartridge, and then reinsert it, making sure it clicks securely into place.
• Check for Protective Tape: Sometimes, new cartridges come with protective tape or seals that need to be removed before installation. Ensure that any protective coverings on the cartridge have been removed.
• Update Firmware: Outdated firmware can sometimes cause issues with cartridge recognition. Visit the HP website and check if there are any firmware updates available for your printer. If there are, follow the instructions to update the firmware.
• Restart the Printer: Turn off the printer, unplug it from the power source, wait for about 30 seconds, and then plug it back in and turn it on. This can sometimes reset the printer and resolve minor issues.
• Clean Contacts: If the printer still doesn't recognize the cartridge, remove it again and clean the electrical contacts on both the cartridge and inside the printer using a lint-free cloth lightly dampened with distilled water. Ensure they are dry before reinstalling the cartridge.
• Try a Different Cartridge: If you have access to another black cartridge, try installing it to see if the issue is with the cartridge itself. If the new cartridge is recognized, the original one may be faulty.

We're thrilled to have the opportunity to assist you and provide a solution.  

When an "Encryption Credentials Expired" error displays on your HP printer while printing from macOS, it is typically caused by an expired Embedded Web Server (EWS) certificate. Here’s how to resolve this issue by generating a new self-signed certificate from the EWS:

• Search for and open the HP Smart app.
• If you do not have HP Smart, download the free app from 123.hp.com or your app store.

Access Printer Settings:

• From the homepage of the HP Smart app, select your printer's name or image.
• Select "Printer Settings".

Open Advanced Settings or EWS:

• Select "Advanced Settings" or "Embedded Web Service (EWS)".
• If a login or certificate window displays, complete the information to open EWS.

Generate a New Certificate:

• Select "Network Summary".
• From the General Network Summary page, scroll down to select "Security".
• Click "Certificates".
• Select "Configure", then "Create a New Self-Signed Certificate".
• Click "Next" to create a new self-signed certificate.
• Click the "Finish" button and close EWS.  

Hope this helps! 

Take care, and have an amazing day!

When turning on your HP printer and all the lights flash with an E on the display, it indicates that the printer is in an error state. Here are common error codes and their solutions for HP Smart Tank series printers:

E1/E2 Paper size mismatch

• Cause: The printer detects that the paper size of the printing job does not match the width or length of the paper loaded.
• Solution:
  1. Press the Cancel button to cancel printing.
  2. Load paper that matches the size of the page you want to print, or change the paper size settings in your application to match the size of the paper you are using.
  3. Print the document again.

E3 The carriage inside the printer has stalled.

E4 There is a paper jam.

  1. Turn off the printer.
  2. Unplug the power cord.
  3. Wait for a minute, and then plug the power cord back in.

@wlgyl, thanks so much for the update — and I’m really sorry to hear the issue’s still clinging on despite those steps. I know how exhausting it is when tech just won’t listen, especially after you’ve already tried the reinstall route.

Let’s dive a little deeper:

Double-check connection magic
Even if the printer works fine from your phone, let’s make sure your PC isn’t on a different band (like 5GHz vs. 2.4GHz Wi-Fi). They feel connected, but often they’re not talking to each other properly.

Try adding it manually

Go to Settings > Bluetooth & devices > Printers & scanners

Click Add device, then “The printer I want isn’t listed”

Choose Add a printer using a TCP/IP address, and enter your printer’s IP (you can find it from the printer’s screen or HP Smart app)

Let me know how that goes — we’re in this together and we’ll get you printing again soon. 🖨️✨

Hope this helps! 

Take care, and have an amazing day!

I had exactly the same issue after a windows update. I removed the printer via Windows Settings (bluetooth, then printer, then remove printer). I resarted the PC and reinstalled the printer via the bluetooth settings. Opened HP Smart then entered the pin when requested and the problem was solved.

Received a printer error message.  Turned off, unplugged and plugged back in and turned back on as directed,   Still getting message.

I have tried this wirelessly already, but I'll have to look around for the cord to try again manually.

when I went to print, it stated "printer is in error state " .  Don't know why;  All the lights are flashing on the top

All the lights are blinking on my printer. I have followed everything to the letter and nothing. Over the past few weeks, it has been storming really badly here in Chattanooga, and I thought that my printer just needed to be reset so it could be used again. so i unplugged it and then when i went to plug it back in and turn it on i got a EE error code while the colored ink icon, the icon with a sheet of paper with a down arrow, the power button, and the information icons were all blinking. as ive stated before, i have tried all the methods to fix the issue and nothing has worked. I'm a university student and need my printer for school. So I need help, please.

I have a brand new LaserJet Pro 4002dw. I have set it to sleep after 5 minutes and I have disabled its shut down feature by setting it to never. I have also checked Disable Shutdown when ports are active. It's with the latest Firmware Version YOSHINXXXN002.2513A.00 Built Date  2025-03-28.
Looks like it shuts down after a day and I can't wake it up by any button or printing job. However the wifi light is on and I can access it from the Embedded Web Server but when I try the Power Cycle feature to restart it it stucks on shutting down.
Every time It requres hard reset from the power button.
Is there a possible solution to prevent it from shutting down?
Is this a software problem? If so is there a way to revert the software update?
