HP LaserJet MFP M140 was working well with desktop PC as well three iOS devices. Couple of days back, I replaced and older router and modem with new one. Now the printer's blue light keeps blinking and is not printing. Ihave tried all methods recommended by HP but the problem persists.

Hello @Pyade, Welcome to the HP Support Community. 

 

Thanks for reaching out about your query regarding the HP LaserJet MFP M140. 

 

We appreciate the opportunity to assist you and are glad we could help work toward a resolution. We hope our support has been valuable.

 

To help us get started on resolving your issue, please make sure that the printer and the device are connected to the same network and they are close to the router. 

 

Use the buttons on the printer control panel to restore Wi-Fi setup mode.

  • If the printer is in sleep mode (the Ready light is on but dim), press the Cancel button to wake up the printer.
  • Press and hold the Wireless button and the Cancel button for five seconds.
  • Pressing the wireless and cancel buttons
  • Wait for the printer to restart and for the Wireless light to blink.
  • Within two hours, return to the app or software to find and add your printer and complete the setup

 

Take care and have an amazing day!

I'm an HP Employee.
