2.4.1.1.1 Using JP1 to Return to Default Settings
JP1-ON forces the module to use the factory default settings for configuration. All settings are
returned to their default values. The unique, factory assigned Ethernet Address and Serial
Number are maintained.
To use JP1, turn the power off to the printer. Remove the E4 module from the printer. Install the
jumper across JP1. Install the module back into the printer. Power on the printer. Wait for the
printer to initialize (printer feeds paper once), then power down the printer again.
Remove the E4 module from the printer and remove the jumper from JP1.
Re-install the E4 back into the printer and power back up.
The E4 is now running with default settings and can be configured using the various utilities
provided.
