Hi @Perth6069,

Welcome to The HP Support Community.  

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

I understand you are getting the "rd" error on your HP LaserJet MFP M234sdwe usually indicates a problem with the ADF (Automatic Document Feeder) or a paper jam. The white flashing light also suggests an issue that requires attention.

 Here's a step-by-step guide to troubleshoot this issue:
 

1. Check for Paper Jams

• Open the ADF and check for any paper that might be stuck.
• Gently remove any jammed paper, making sure there are no torn pieces left inside.
• Also, check the paper path inside the printer.

2. Reset the Printer

• Turn off the printer and unplug it from the power source.
• Wait for about 1-2 minutes, then plug the printer back in and turn it on.

3. Check for ADF Obstructions

• Open the document feeder tray and check if there are any obstructions like dust, paper clips, or small debris.
• Clean the ADF rollers if you notice any dirt.

4. Update Firmware Update the firmware on an HP printer

• Ensure that your printer firmware is up to date. You can download the latest firmware for your printer from the HP Support website.

5. Check for Hardware Issues

• Ensure all doors and trays are fully closed.
• Make sure the paper tray is properly loaded with paper aligned correctly.
