@Mayank180, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Blinking Light on HP LaserJet Pro MFP M126nw! 

We're thrilled to have the opportunity to assist you and provide a solution.  

The blinking triangle with an exclamation mark (!) on your HP LaserJet Pro MFP M126nw indicates an error that needs urgent attention. Here are the steps you can take to troubleshoot this issue:

Check the Display Screen:

• If the display screen is blank, ensure that the printer is powered on and the power cord is securely connected to a working power outlet.

Identify Error Codes:

• Look for any error codes or messages that might appear briefly on the screen when you power on the printer. These can provide specific guidance on what needs fixing.

Paper Jams:

• Ensure there are no paper jams inside the printer. Check the input tray, output bin, and any other accessible areas for blockage.
• Clear any jammed paper, if present, according to the instructions in your printer's manual.

Toner Cartridge Check:

• Inspect the toner cartridge for any damage or incorrect installation.
• If the toner cartridge is low or needs replacement, the triangle light might blink to indicate this.

Reboot the Printer:

• Turn off the printer by pressing the power button.
• Disconnect the power cord from the outlet and wait for about 30 seconds.
• Reconnect the power cord and turn the printer back on.

Check for Obstructions:

• Ensure that all printer doors and covers are closed securely.
• Look for any obstructions in the paper paths and remove them.

Reset the Printer Settings:

• If you have recently made changes to the printer settings, you may try resetting them to default to see if that resolves the issue.  

Hope this helps! 

Take care, and have an amazing day!
