I keep getting notifications from HP that just say 'null'. Ive had the printer about 3 weeks and have gotten the null message maybe 6-9 times.

Hi @Dogmama925,

Welcome to the HP Support Community.
 

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

If your HP printer is sending notifications that just say “null”, it’s likely a firmware or app communication bug, especially since you’ve only had the printer for about 3 weeks. Here are a few steps in resolving this issue:

What “null” Notifications Usually Mean

• These are placeholder messages that appear when the printer or HP Smart app fails to load the actual notification content.
• It can be caused by:
  • A firmware glitch.
  • A corrupted app cache.
  • A network sync issue between the printer and HP cloud services.

HP Recommended Fixes

1. Update Printer Firmware

• Go to the Official HP® Drivers and Software Download | HP® Support page.
• Enter your printer model (e.g., HP Smart Tank 6001 or Envy Pro 6400).
• Download and install the latest firmware update.

Firmware updates often fix bugs like “null” notifications.

2. Clear HP Smart App Cache (Mobile or PC)

• On Windows:
  • Go to Settings > Apps > HP Smart > Advanced Options > Reset.
• On Android:
  • Go to Settings > Apps > HP Smart > Storage > Clear Cache.
• On iOS, uninstall and reinstall the app.

3. Re-add Printer in HP Smart App

• Remove the printer from the app.
• Restart your phone or PC.
• Re-add the printer using the Add Printer option.

4. Factory Reset the Printer (if needed)

• For most HP printers:
• Press and hold the Wireless + Cancel buttons until the power light blinks.
• This restores Wi-Fi setup mode and clears cached settings

I hope this helps.

Take care and have an amazing day!
