If the HP Embedded Web Server (EWS) local administrator password was set on the host HP printer when the HP Jetdirect 2800w NFC & Wireless Direct Accessory is installed, you must synchronize this password between the two devices. To do this, first clear the existing local administrator password field on the host HP printer, and then reenter it.
note:
If the HP EWS local administrator password was not set on the host HP printer during the installation, no changes are required and you can skip this section.
Failure to properly synchronize the HP Jetdirect 2800w NFC & Wireless Direct Accessory with the HP printer's local administrator password might cause printing issues.
Use the following to synchronize the passwords:
-
From the
Home screen on the host HP printer 's control panel, touch the network

button to display the printer's LAN IP address or host name.
-
Open a Web browser, and in the address line, type the printer's IP address or host name exactly as it displays on the product control panel. Press the Enter key on the computer keyboard. The EWS opens.
-
Select the Security tab, and then select General Security from the left panel options.
-
Scroll to the Set the Local Administrator Password section.
-
To clear the existing password, type the HP EWS administrator password used on the host HP printer in the Old Password text box. (Do not type anything in the New Password or Verify Password boxes. These must remain blank.)
-
Click the Apply button.
-
Verify that the Old Password text box displays Password is not set.
If the Old Password text box does not display Password is not set, repeat the steps to clear the password.
-
To synchronize the password on the two devices, type the HP EWS administrator password in the New Password text box, and then type it again in the Verify Password text box to confirm.

Click the Apply button.
