If you've recently encountered problems with your HP Smart Tank 670 printer after replacing the printhead, you're not alone. Users have reported issues like all lights blinking, rendering the printer unusable. In this technical overview, we'll explore potential solutions to get your printer back in working order.

Understanding the Printhead Issue: The HP Smart Tank 670 printer is known for its efficient printing capabilities. However, users occasionally face problems, particularly with the printhead. If your printer stopped printing a specific color, like red ink, replacing the printhead is a common and seemingly straightforward solution.

Replacing the Printhead: The process of replacing the printhead is generally simple. Users can purchase an original printhead and follow the provided instructions to swap out the old one. However, as reported by some users, this seemingly easy fix can lead to a new set of challenges.

Troubleshooting the Blinking Lights Issue: If you find yourself in a situation where all lights on your HP Smart Tank 670 are blinking after replacing the printhead, follow these steps to troubleshoot the problem:

1. Power Cycle the Printer: Start by turning off the printer, waiting for a few minutes, and then turning it back on. This basic step can sometimes resolve temporary glitches in the printer's system.
2. Check Connections: Ensure that all connections, including power and data cables, are securely plugged in. Loose connections can cause communication issues, leading to the blinking lights problem.
3. Reset the Printer: Most printers come with a reset option. Consult your printer manual to locate the reset function and follow the instructions to reset the device.
4. Inspect for Jammed Paper: Sometimes, a small piece of paper or debris may be causing the issue. Open the printer and carefully check for any jams or foreign objects that might be obstructing the printer's normal operation.
5. Update Firmware: Outdated firmware can lead to compatibility issues. Visit the official HP website, locate your printer model, and download the latest firmware update. Follow the installation instructions to ensure your printer is running on the most recent software.
6. Perform a Hard Reset: If the problem persists, perform a hard reset by disconnecting the power cable, waiting for at least 60 seconds, and then reconnecting it. This can sometimes resolve more stubborn issues.

After attempting these troubleshooting steps, monitor your printer to see if the issue persists. If the blinking lights problem continues, it may be worthwhile to contact HP customer support for further assistance.
