Did you make any changes to your printer? 🛑The default username and password for your printer would be blank or admin for both username and password. However, if you still have issues try performing a factory reset on your printer and check if it helps. 1.
If your USB printer is not found by the HP Smart app, make sure Windows is up to date, check for USB connection issues, and then reinstall the app. Note: An HP+ or eligible printer cannot enroll in HP Smart Advance or Instant Ink using a USB connection.
The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Check the printer connection status: Make sure the wireless signal is on, and the printer is connected to the same network as your computer or mobile device. If your printer has a light next to a Wireless icon or button , make sure the light is on. If it is off or blinks the printer is disconnected from the network.
Start by checking your hardware
If you`re using a wired printer, make sure that the printer cable is properly connected from the printer to your PC. For wireless printers, check the wireless connection. Make sure the printer`s wireless option is turned on and available.
Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.
