Hi @lfsditto,

Welcome to the HP Support Community.
 

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

Seeing error code 19a0042 on your HP printer can feel like hitting a wall, especially when you're in the middle of something important. You're not alone in this, and I’m here to help you get back on track.

Steps to Fix Error 19a0042

Step 1: Power Reset

  1. Turn off the printer.
  2. Unplug it from the wall (not just the back).
  3. Wait 2 minutes.
  4. Plug it back in and turn it on.

This clears temporary memory glitches.


Step 2: Reseat the Printhead

  1. Open the printer access door.
  2. Gently remove the printhead and cartridges.
  3. Clean the electrical contacts with a lint-free cloth.
  4. Reinstall the printhead and cartridges securely.

Be gentle, printheads are sensitive and need precise alignment.


Step 3: Update Firmware

Outdated firmware can cause detection issues.

  • Visit the Official HP® Support and enter your printer model.
  • Download and install the latest firmware for macOS.


Step 4: Use HP’s Diagnose & Fix Tool

HP offers a built-in tool in the HP Smart app for Mac:

  1. Open the HP Smart app.
  2. Click your printer > Diagnose & Fix.
  3. Follow the on-screen instructions.

I hope this helps.

 

Take care and have an amazing day!
