Is your printer flashing at the worst possible moment, just when you have an urgent document to print? Don't panic! This handy guide will help you quickly identify the problem and apply an effective solution to get your printer working again.

1. Check that the printer cover is properly closed

A poorly closed cover may trigger a warning light and prevent the printer from operating.

✅ Solution: Make sure the cover is properly latched, then restart your printer.

2. Check the paper and ink (toner) levels

An empty tray or an exhausted cartridge can block your printer.
• Check the paper tray: It must be full and the sheets must be properly aligned.
• Inspect the cartridges/toners: Check that they are not empty and that they are properly installed.

Tip: After these checks, restart the printer and perform a test print .

3. Update or reinstall printer drivers

An outdated or corrupted driver can cause malfunctions.

🔍 Where to download the latest drivers?

Go to the official website of your printer manufacturer:
🔹 HP France: support.hp.com/fr
🔹 Canon France: www.canon.fr/support
🔹 Brother France: www.brother.fr

You can also use Windows Update or specialized software like Driver Booster to make updating easier.

✅ Once the update is complete, test your printer.

4. Check the power connection

An unstable power supply can also cause the indicator light to flash.

Checks to be carried out:
• Inspect cables and plugs: Make sure everything is plugged in properly and the plug is working properly.
• Try another outlet or adapter: This will rule out any power issues.

⚠️ Caution: A faulty power supply may prevent your printer from starting. Take the time to check each connection carefully.
