The Wireless light blinks

The Wireless light blinks when a connection is configuring or when the printer cannot find a wireless signal or cannot connect to the network.

Step 1: Wait for the printer to establish a connection

The Wireless light blinks when the printer is attempting to connect to the wireless router or access point. Wait a few minutes, and then check the light again.
  • If the Wireless light is on and steady, the printer is connected and you can stop troubleshooting.
  • If the Wireless light is still blinking, continue to the next step.

Step 2: Check for issues with the wireless network

The following factors can cause the printer to lose the wireless connection:
  • The network connection is no longer active, or has low signal strength.
  • The printer goes into sleep mode or standby mode.
  • The printer is either too far away from the wireless router, or too close to it. The recommended distance between the printer and the router is 1.0 meter to 1.5 meters (3 ft to 5 ft).
  • A firewall prevents the printer from accessing the computer and wireless network.
  • A nearby device that emits radio signals (such as a microwave or cordless telephone) might interfere with the wireless connection.
  • A virtual private network (VPN) prevents the printer from accessing the computer and wireless network.
Check the Wireless light after correcting any items on the list.
  • If the Wireless light is on and steady, the printer is connected and you can stop troubleshooting.
  • If the Wireless light is still blinking, continue to the next step.

Step 3: Connect the printer to your network

For more information about connecting the printer to the wireless network by installing the printer software, see the following documents.
  • HP LaserJet Pro P1102w and P1109w printers: Go to Wireless Printer Setup.
  • HP LaserJet Pro M12w printers: Go to Wireless Printer Setup (Windows).
  • HP LaserJet Pro M12w printers: Go to Wireless Printer Setup (OS X).

The Attention light blinks

The Attention light  blinks when the printer is in an error state due to missing toner cartridge, the top cover is not properly closed, or the paper is not loaded correctly or is jammed.

The Attention light blinks, and the toner cartridge might be missing

This condition occurs when the toner cartridge is absent or not installed correctly. To resolve the issue, reinstall the toner cartridge.

Step 1: Examine the toner cartridge area

Open the top cover, and then check the toner cartridge.
Figure : Opening the top cover
  • If the toner cartridge is missing, install the missing toner cartridge.
  • If the toner cartridge is in the printer, it might not be installed correctly. Remove the toner cartridge, and then reinstall it.

The Attention light blinks, and the paper might be missing or not properly loaded

This condition occurs if the priority feed slot or input tray is empty. To resolve the issue, load plain paper into the priority feed slot or the main input tray.

Load plain paper print side facing up into the priority input tray. For more information about loading paper, go to Loading Paper, Envelopes.

Load paper into the input tray

Load plain paper print side facing up into the input tray. For more information about loading paper, go to Loading Paper, Envelopes.

The Attention light blinks, and the paper might be jammed

This condition occurs when paper is jammed inside the printer. To resolve the error, find and clear the printer of any jammed paper, or reset the printer if the printer has no jammed paper. For more information about resolving paper jam issues, go to Clearing a Paper Jam to remove jammed paper from the printer.

The Attention and Ready lights are on

This condition occurs when the printer is in a fatal error state.

Figure : Plugging in the power cord

Step 3: Plug the printer directly into a wall outlet

If you are using a surge protector, extension cable, or power strip, plug the printer directly into a wall outlet to make sure the power source functions correctly.
  1. Unplug the power cord from any surge protector, extension cable, or power strip.
  2. Plug the power cord directly into a wall outlet.
  3. Turn on the printer.
If the printer does not turn on, continue to the next step.

Step 4: Make sure the electrical outlet works

Make sure the electrical outlet the printer is plugged into is providing power.
  1. Unplug the power cord from the electrical outlet.
  2. Plug another appliance into the electrical outlet to make sure the outlet works.
  • If the electrical outlet does not work, plug the printer into another outlet that does work.
  • If the electrical outlet works, but the printer still does not turn on, continue to the next step.

Step 5: Test the power with a compatible power cord from a different printer

If you have another available power cord that is compatible with your printer, use the alternate cord to repeat the steps to test the power.
  • If the printer does not turn on with the alternate power cord, continue to the next step to service the printer.
  • If the printer turns on with the alternate power cord, the original power cord caused the issue. Contact HP to replace the power cord.

Step 6: Service the printer

If you have completed all the previous steps and the issue persists, continue to the Service the printer section at the end of this document.
