Set Info Restore; Cap Pump Check; Log Level - Brother GTX-4 Service Manual

3-1-5-12. Log level

This is a menu item used for the determination of cause for defective operation and not used under normal
circumstances.
Item enables selection of only the basic logs or detailed logs for operational logs recorded within the printer. However,
the "duration of log accumulation becomes extremely short" in the event a detailed operation log is recorded.
Initial setting is "Standard information" logging. Use printer on this setting unless required by the manufacturer. If
switching to "Detailed information" logging mode, be sure to restore mode to "Standard information" after use.

3-1-5-13. Set info restore

Portions of information recorded on the main circuit board are backed up by the panel circuit board.
Upon replacement of the main circuit board, the data backed up within the panel circuit board may be restored onto the
main circuit board using the GTX-4 Service Tool. For details, refer to "6-2-4. Replacement of main circuit board".
Under normal circumstances, part replacement process using the GTX-4 Service Tool should always be implemented
upon replacement of the main circuit board.
As emergency measures in case the GTX-4 Service Tool is unavailable for restoration, the Advanced menu provides the
menu item [Set Info Restore]. The backup data registered within the panel circuit board may be restored onto the main
circuit board by executing this menu item, but this is intended for emergencies only, and is incapable of substituting all
activities required after the replacement of the main circuit board.
