Hi @Luca19731, Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The system initialization loop on your HP Color Laser MFP 179fnw could be caused by firmware corruption, a hardware issue, or a failed component. Since you have already tried a hard reset, here are additional steps to troubleshoot and potentially resolve the issue:
Power Reset with Extended Unplugging
- Turn off the printer and unplug it from power.
- Disconnect all cables (USB, Ethernet, phone line).
- Leave the printer unplugged for 10-15 minutes.
- Plug it back in directly to a wall outlet (avoid surge protectors).
- Turn it ON and check if the issue persists.
Check for Firmware Corruption
If the printer keeps looping during initialization, firmware corruption might be the cause.
Try a forced firmware recovery:
- Download the latest firmware for your printer from HP support page: Click here
- Turn off the printer.
- Connect the printer via USB to a Windows PC.
- Open the firmware update tool and start the update before turning on the printer.
- Turn on the printer while the update is in progress (this might force a recovery).
Check for Paper Jams or Sensor Issues
Sometimes, a small paper fragment inside the printer can cause continuous initialization:
- Open all doors and inspect for jams (use a flashlight).
- Remove and reseat the toner cartridges.
- Check the sensor flags (small plastic tabs near the paper path) to ensure they move freely.
Check Network & Fax Connections
If your printer is connected to a network (Ethernet or Fax line), try:
- Disconnecting the Ethernet cable and booting up.
- If connected to a phone line (Fax), unplug it and restart.
Service Mode Reset (NVRAM Reset)
If the problem persists, try resetting the printer’s NVRAM (Non-Volatile Memory):
- Turn off the printer.
- Press and hold Stop (🔴) and Start Copy (🖨️) simultaneously.
- While holding, turn the printer ON.
- Keep holding the buttons for 10-15 seconds until the printer resets.
I hope this helps.
Take care and have a good day.
