Hitachi j300 I need to restore the parameters to factory settings, how do I do this..?

Check the manual for instructions on resetting the parameters.

If you already saved your configuration (in the parameter setting -> privacy -> Save my parameters) you can restore them by using the factory reset, android system will offer you to use your saved parameters (with your google account), else, you'll have to refile it, sorry

Try:

To restore factory defaults:

1. POR the machine into Configuration Mode.

2. Use the down navigation button to scroll to the RESTORE

FACTORY DEFAULTS item on the menu.

3. Press Select. The machine performs a POR.

4. The RESTORE FACTORY DEFAULTS sets the MFP non critical

parameters back to the factory settings.

Note: Some settings are not affected: panel language, energy
conserve, paper prompts, registration margins, and page count.

Below are the command sequences that can be applied to default the parameters referenced above:
Examples:
! U1 do "device.restore_defaults" "bluetooth"
! U1 do "device.restore_defaults" "ip"
! U1 do "device.restore_defaults" "wlan"
! U1 do "device.restore_defaults" "power"
! U1 do "device.restore_defaults" "display"
The zpl parameters can be restored to their factory defaults on the P4T series, RW series and QLPlus series by deleting the ZPL_CFG.CFG file. This binary file contains the zpl settings and will be recreated automatically when restarting the printer. The newly created file will contain the binary equivelant of the factory zpl default settings.
The ZQ500, QLn series and the iMZ allows the ^JUF and ^JUN command to be sent to restore parameters to their factory default condition.
Example: ^XA^JUF^XZ^XA^JUN^XZ^XA^JUS^XZ
Please note that the iMZ uses line print mode by default. The command ! U1 setvar "device.languages" command may need to be adjusted to se the iMZ back to ZPL if necessary.
! U1 setvar "device.languages" "zpl"

Log in to the switch as an administrative user (using the login command).

You can type the following command:

reset {config|system}

If you type "reset config" all of the factory default settings are restored on the switch except for the IP address, user
accounts, and the switch history log.

If you type "reset system" all of the factory default settings are restored on the switch.

If you just type "reset" by itself, the switch’s current IP address, user accounts, and switch history log are retained. All other
parameters are restored to their factory default settings.
