Service mode functions

Cold reset

A cold reset unlocks menus that have been previously locked and sets all control panel menu items (including EIO settings) back to the factory defaults. However, it does not clear the values in the SERVICE menu (such as the serial number and page counts).

NOTE Before performing a cold reset, print a menu map and a configuration page (see Use information pages on page 38). Use the information on the configuration page to reset any customer-set device configuration values that the cold reset procedure changes.

1.Turn the device off.

2.Turn the device on. When the memory count begins, press and hold the button. Continue holding down the button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.

3.After the message SELECT LANGUAGE appears on the display, press the button or the button until COLD RESET is highlighted.

4.Press . The device performs a cold reset and then continues its power-on sequence.

5.Check all I/O settings and reset any customer-set device configuration values.

NVRAM initialization

CAUTION Initializing the NVRAM resets the serial number, the event log, the page counts, and the EIO card (initializing the NVRAM resets SERVICE menu values to factory defaults). Use the service menu to restore the serial number and page counts. Also reconfigure any computers that print to this device so that the computers can recognize the device. Initialize the NVRAM only when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization to reset device settings (this will retain the values in the SERVICE menu).

NOTE Before performing a NVRAM initialization, print a menu map and a configuration page (see Use information pages on page 38). Use the information on the configuration page to reset any customer-set device configuration values that the NVRAM initialization procedure changes. Take special note of thetotal page count, maintenance count, and the serial number.

1.Remove any installed accessories.

2.Turn the device off.

3.Turn the device on. When the memory count begins, press and hold the button. Continue holding down the button until all three device control-panel lights flash once and then remain on. This might take up to 10 seconds.
