Hi @Sparky255,

Welcome to HP Support Community.

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

When your HP Color LaserJet Pro MFP M377dw indicates a paper jam but no paper is visibly stuck in Tray 1 or Tray 2, it can be quite frustrating. Here are some comprehensive steps to troubleshoot and resolve the issue:

Step 1: Power Cycle the Printer

1. Turn off the printer and unplug it from the power source.
2. Wait for about 60 seconds.
3. Plug the printer back in and turn it on.

Step 2: Check All Paper Paths

1. Remove All Paper Trays:
   • Take out Tray 1 and Tray 2 and inspect them thoroughly for any small bits of paper or debris.
2. Check the Rear Access Door:
   • Open the rear access door or duplexer and inspect the area for any hidden paper jams.
3. Inspect the Fuser Area:
   • Open the fuser access door and carefully inspect the area. Sometimes, small pieces of paper can be lodged in the fuser assembly.
4. Check the Automatic Document Feeder (ADF):
   • If your printer has an ADF, open it and inspect for any jams or small pieces of paper.

Step 3: Clean the Printer Rollers

1. Clean the Rollers:
   • Use a lint-free cloth slightly dampened with water to clean the paper rollers. Gently rotate the rollers to clean the entire surface.
2. Inspect for Damage:
   • Check the rollers for any signs of wear or damage. Worn-out rollers can cause false paper jam errors.

Step 4: Update Printer Firmware

1. Check for Firmware Updates:
   • Ensure your printer firmware is up to date. Visit the HP support website, search for your printer model, and download the latest firmware updates.

Step 5: Reset the Printer

1. Factory Reset:
   • Performing a factory reset can sometimes resolve persistent issues. Be aware that this will reset all settings to default.
   • To perform a factory reset, navigate to the printer's control panel:
     • Go to Setup > Service > Restore Defaults.
     • Confirm the reset process and wait for the printer to restart.

Step 6: Check for Sensor Issues

1. Inspect Paper Sensors:
   • Paper sensors can sometimes get stuck or dirty, causing false paper jam errors. Carefully inspect and clean the sensors with a soft brush or compressed air.

Step 7: Test with Different Paper

1. Use Different Paper:
   • Try using a different batch or type of paper to rule out any issues with the paper itself.

Step 8: Perform Printer Diagnostics

1. Run Diagnostics:
   • Use the printer's built-in diagnostics tools to check for hardware issues. Navigate to Setup > Reports > Printer Status Report to see if there are any errors reported.

I hope this helps.

Take care and have a good day.
