Step 1: Locate the hole on the back of the print server above the word RESET.


Step 2: Using a paper clip, press and hold the Reset button for about 5 seconds and then release.

Step 3: After the print server reboots it will be reset to the factory default settings.

    I have a DP-300U print server. How do I reset it to factory default setting? I tried to use PS Admin. But it keeps on asking me for a password, which I don’t have.

      The password asked by the program is try “SYSxxxx”, where xxxx means the last four digits of the MAC address of your server. (Example: if your MAC address were “12 34 56 A8 FE”, then your password would be SYSA8FE.)

      D-Link DP-300U Rev. H/W Ax, Bx has no reset button. Is it possible to reset the device without knowing the old password?
      If you try via PS Admin (v3.0 & v2.1) the utility program requires a password that you do not know.

            Try that scripts in browser, but first change that “” with your DP-300U IP Address, use PSAdmin utility or Trendnet utility to know it.

              Hey. I know this comment is almost 5 years old, but it just saved my butt. Worked perfectly on an old DP-301P+ whose password was long since forgotten.

              So, if you happen to read this many years later, thanks!
