[User04092022]

Hi

I have djia4100 printer and I have a issue with Printer PIN invalid error when I try to setup on HP Smart on my Android phone or Windows 10 laptop. How do I fix this?

I tried all the ways suggested by HP Smart Doc, blah blah.. Nothing seems to work.

Welcome to the HP Support Community.

I'd be happy to help.

Uninstall and reinstall the HP Smart App on both your Computer and phone.

If the issue persists, let's do a root uninstall and reinstall of the software on your Computer:

Unplug any USB cable, if any, before doing this.

1.) In Windows, search for and open Programs and features

2.) Select your HP Printer

3.) Select Uninstall

4.) In Windows, search for and open Devices and printers

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose 'Delete' or 'Remove Device'

6.) Open up the run command with the "Windows key + R" key combo.

7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers

13.)  Open up the run command with the "Windows key + R" key combo.

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:
