Hi @LcB11, Welcome to the HP Support Community!

Thanks for reaching out! 

Here are some troubleshooting steps to resolve the error on your HP Officejet Pro 8600 e-All-in-One Printer (N911a) after replacing all four cartridges:

Check the Error Message

If your printer screen displays a specific error code or message, note it down. This can help pinpoint the exact issue.

Verify the Cartridges

• Ensure you are using genuine HP ink cartridges for the Officejet Pro 8600. Non-HP or third-party cartridges can cause errors.
• Confirm that all four cartridges are properly clicked into place.
• Check for any protective tape on the cartridges that may still be covering the ink nozzles.

Clean the Printhead Contacts

Since you already cleaned the cartridge area, try this next:

1. Turn off the printer and unplug it from the power source.
2. Remove the cartridges.
3. Take a lint-free cloth slightly dampened with distilled water and gently clean the electrical contacts on the printhead (inside the printer).
4. Let it dry for a minute, then reinsert the cartridges.
5. Power the printer back on.

Reset the Printer

Perform a hard reset:

1. Turn off the printer and unplug the power cord from the wall outlet.
2. Wait 3-5 minutes.
3. Plug the printer back in and turn it on.
4. Check if the error clears.

Check for Paper Jams & Internal Issues

• Open the printer and check for any small paper fragments or dust buildup.
• Remove and reinsert the printhead (if possible, depending on your model).

Update Printer Firmware

• If your printer is connected to Wi-Fi, go to Setup > Printer Maintenance > Update the Printer.
• If not, check HP's website for firmware updates.

Try a Semi-Full Reset (Last Resort)

This resets the printer to factory settings:

1. Turn off the printer.
2. Press and hold the bottom-left and bottom-right corners of the touchscreen while turning the printer back on.
3. Follow on-screen prompts to complete the reset.

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful!

Take care, and have an amazing day!

Hi @maxgo, Welcome to the HP Support Community!

Thanks for reaching out about your query regarding Missing or Damaged Printhead" (19A0027) error! 

Since you've already replaced the printhead and followed troubleshooting steps multiple times, but the HP OfficeJet Pro 8620 still displays the "Missing or Damaged Printhead" (19A0027) error, try the following advanced solutions:

1. Perform a Full Printer Reset

1. Turn off the printer and disconnect the power cord from both the printer and the wall outlet.
2. Wait for at least 10 minutes to ensure a full power reset.
3. Reconnect the power cord directly to a wall outlet (not a surge protector).
4. Turn the printer back on and check if the error persists.

2. Clean Printhead and Contact Points

1. Open the printer and remove the printhead.
2. Check the gold contacts on the printhead and inside the printer for dust or ink residue.
3. Use a lint-free cloth lightly dampened with distilled water to clean the gold contacts.
4. Let it dry completely before reinserting.

3. Reinstall the Firmware via USB

If the printer firmware is corrupt, reinstalling the firmware might resolve the issue.

1. Download the latest firmware update for the HP OfficeJet Pro 8620 from the HP Support website.
2. Connect the printer to a PC via USB cable (even if you normally use Wi-Fi).
3. Run the firmware update file and follow on-screen instructions to update.

4. Reset Printer to Factory Settings

1. On the printer's control panel, press the Back (◀️) button four times to open the Support menu.
2. Navigate to Reset Menu > Semi-Full Reset.
3. Confirm the reset. The printer will restart.

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful!

Hi @PayneIan, Welcome to HP Support Community. 

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

If the printer reports a Paper Jam but there's no visible paper inside, and the rollers are not moving, the problem could be due to sensor issues, roller misalignment, or a mechanical failure.

Troubleshooting Steps

1. Hard Reset the Printer

• Turn off the printer and disconnect it from power.
• Wait 2-3 minutes before plugging it back in and turning it on.
• Check if the error persists.

2. Check for Hidden Paper Jams

• Open all access panels (input tray, output tray, rear panel).
• Use a flashlight to check deep inside the printer for small torn pieces of paper or debris.
• Remove any obstructions gently.

3. Manually Rotate the Rollers

• Turn off the printer and unplug it.
• Open the rear access door or duplexer (if installed).
• Locate the paper feed rollers and gently rotate them manually to see if they are free or stuck.
• If they don’t move, try cleaning them (see Step 4).

4. Clean the Paper Rollers

• Use a lint-free cloth slightly dampened with distilled water or isopropyl alcohol.
• Gently wipe the rollers to remove dust, debris, or dried ink.
• Let them dry completely before turning the printer back on.

5. Reset the Paper Sensor

• Open the front panel and look for the paper path sensor (usually a small plastic flap near the rollers).
• Ensure it's not stuck or bent.
• If stuck, gently move it back and forth to reset it.

6. Check the Encoder Strip

• The encoder strip is a clear plastic strip behind the printhead that helps the printer track movement.
• If dirty or out of place, clean it gently with a dry lint-free cloth.

7. Perform a Printer Self-Test

• On the printer's control panel, go to Setup > Printer Maintenance > Clean Page Smears to force the rollers to engage.
• If they still don’t move, the issue may be mechanical.

8. Update Firmware

• Ensure the printer firmware is up to date by checking on HP website.
• Some firmware updates fix phantom paper jam errors.

I hope this helps. 

Take care and have a good day.

Hi @LRogers23, Welcome to HP Support Community.

Since you've already tried changing the cartridge, cleaning the printhead, and checking the sensors without success, here are some additional troubleshooting steps to resolve the issue with your HP OfficeJet Pro 6978:

1. Check the Cartridge Vent

• Remove the problematic cartridge.
• Inspect the vent (small hole on top). If it's clogged, gently clean it with a pin or paperclip.
• Reinstall the cartridge and check if it works.

2. Perform a Deep Printhead Cleaning

• Go to the printer’s control panel.
• Navigate to Setup > Printer Maintenance > Clean Printhead.
• If the first cleaning cycle does not fix the issue, run up to three cleaning cycles.

3. Check for Printhead Failure

• Print a Print Quality Diagnostic Report:
  • From the printer menu, go to Setup > Reports > Print Quality Report.
  • Look for missing colors or faded sections in the report.
  • If a specific color is missing, it could indicate a printhead failure.

4. Reset the Printer

• Remove all ink cartridges.
• Power off the printer, unplug it from the power source, and wait 5-10 minutes.
• Plug the printer back in, turn it on, and reinstall the cartridges.

5. Update Printer Firmware

• Go to HP Support and check for any firmware updates.
• Install the latest update and restart your printer.

6. Try a Hard Reset

• With the printer powered on, disconnect the power cord from the back.
• Unplug it from the wall outlet and wait 60 seconds.
• Plug it back in and power it on.

I hope this helps. 

Take care and have a good day.

Hi @Donno4, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The "File Corrupt" message on your HP Color LaserJet Pro MFP M277dw when using macOS Monterey (12.0) is likely due to a driver issue, macOS security settings, or a problem with the printing system. Try the following troubleshooting steps:

Reset the Printing System

1. Click on the Apple menu () > System Preferences> Printers & Scanners.
2. Right-click (or hold Control and click) on the printer list and select Reset printing system.
3. Confirm by clicking Reset.
4. Restart your Mac and re-add the printer.

Reinstall HP Printer Drivers

1. Uninstall HP Software:
2. Download the Correct Driver:
   • Go to HP’s official website: HP Software & Driver Downloads.
   • Search for your printer model: Color LaserJet Pro MFP M277dw.
   • Download and install the latest macOS-compatible HP Print Drivers.
3. Reinstall & Set Up:
   • You can use HP smart app and reinstall. 

Use Apple’s Built-in AirPrint (Instead of HP Drivers)

1. Go to System Preferences > Printers & Scanners.
2. Click + (Add Printer).
3. Select your HP M277dw.
4. Under Use, select AirPrint (instead of HP drivers).
5. Click Add and try printing again.

Check for macOS Security Permissions

macOS security settings may block some HP software.

1. Go to System Preferences > Security & Privacy.
2. Under the General tab, look for any messages about HP software being blocked.
3. If found, click Allow.

Try Printing from Preview or Safari

If the error happens only in certain applications, try printing a PDF from Preview or a webpage from Safari. This can help determine if the issue is app-specific.

Check for macOS Updates

• Apple menu () > System Preferences> Software Update.
• If an update is available, install it and restart.

I hope this helps. 

Take care and have a good day.

Hi @djmoorejr, Welcome to HP Support Community. 

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

It looks like your printer is stuck on the firmware update screen. Try these troubleshooting steps:

1. Power Cycle the Printer

1. Unplug the power cable from the printer while it's on.
2. Wait 60 seconds.
3. Plug the power cable back in and turn the printer on.

If the printer reboots but still asks for firmware, try updating again:

• Use HP Smart to check for available updates.
• If using a USB connection, ensure it's plugged directly into your computer (not through a hub).

3. Perform a Hard Reset

1. Turn off the printer.
2. Press and hold the Wi-Fi + Cancel buttons (or Power + Cancel, depending on the model).
3. While holding the buttons, turn on the printer.
4. Release the buttons when the screen turns on.

4. Reattempt the Firmware Update:

• Via USB: Download the latest firmware from the printer manufacturer's website, save it to a USB drive, and follow the instructions to update the firmware using the USB drive. 
• Via Software: Use the printer's software utility on your computer to reattempt the firmware update

I hope this helps. 

Take care and have a good day.

Hi @Beyond2025,

Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check the Printer’s Connection Status:

• First, confirm that your printer is powered on and connected to the local network via Wi-Fi.
• Look for any lights on the printer that may indicate its status. If the lights are flashing or yellow, this typically means there’s an issue.

Restart the Printer:

• Turn the printer off, wait 30 seconds, and then turn it back on. This can sometimes reset the device and resolve minor glitches.
• After restarting, try pressing the Info button again to check if the Wi-Fi Direct option is accessible.

Restore Network Defaults (Factory Reset):

If the Wi-Fi Direct option still isn't working, you might need to restore your printer’s network settings to default:

• Press the Cancel button to ready the printer.
• Press and hold the Wireless button and Cancel button simultaneously until the Power button blinks.
• Wait 60 seconds until the Wireless light blinks blue.
• Within two hours, return to the app or software to find and add your printer and complete the setup.

Use the Printer’s Web Interface (if applicable):

Some printers have an embedded web server that you can access by entering the printer’s IP address in a web browser.

• Find your printer’s IP address (usually printed on a network configuration page).
• Open a web browser and type the printer’s IP address into the address bar.
• Log in (if needed), then go to the Network Settings section.
• Look for the Wi-Fi Direct option and turn it on from the web interface.

Check for Firmware Updates:

Your printer might have a firmware update that could fix the issue.

• Go to the printer manufacturer’s website and search for the latest firmware for your printer model.
• Follow the instructions on how to update the firmware.

Use Printer’s Mobile App (Optional):

If your printer has a mobile app (like HP Smart), you might be able to set up or control Wi-Fi Direct through the app:

• Download the app on your phone or tablet.
• Open the app and connect to the printer using the app’s instructions.
• Once connected, you should be able to enable or manage Wi-Fi Direct.

You can refer to these guides for troubleshooting issues related to Wi-Fi connections and edge lighting, and status lights.

I hope these steps help resolve the issue
