How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Sometimes power cycling your printer can resolve the issue. Turn off your printer and unplug it, wait 30 seconds, plug your printer back in, and then turn the printer back on.
Start the Network Card Setup Utility. Select this machine from the list. Select [IP Address] from the [Actions] menu. Specify the settings as necessary, and click [Config].
The factory default password is “123456”. To change settings of the machine on the Web page, you must log in as the administrator of the machine.
The password is the same as the “administrator password” on the operator panel. The factory default administrator password is “999999”. If the administrator password is changed, enter the updated password.
Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on. On the taskbar, select the Search icon, type Printers in the search bar, and then select Printers & scanners from the search results to open the Printers & scanners system setting.
Check that the same IP address is set for the machine and the machine`s port setting on the computer. Check that the IP address is not duplicated by another device. Check that the correct IP address, subnet mask, and gateway address are set. If using OKI LPR Utility, check the IP address setting with OKI LPR Utility.
