GW Machine

The GW machine (the machine with the optional controller box) stores the engine data in the NVRAM on the BICU, and stores the other data in the NVRAM on the optional controller. To distinguish between the engine data and the other data, see SP5-801-003 through 015. This service program (SP5-801) handles the controller data. Any data that is not handled by SP5-801 is the engine data. The data in the BICU NVRAM (engine data) is cleared by SP5-998-001 while the data in the controller NVRAM (controller data) is cleared by SP5-801-xxx (for exceptions, see "Exceptions" as described below).

Machine	Data	NVRAM	Cleared by	Remarks
GW	Engine data	BICU	SP5-998-001	Any data other than controller data
	Controller data	Controller	SP5-801-xxx	SCS, IMH, MCS, Copier application, Fax application, Printer application, Scanner application, Web service/network application, NCS, R-Fax, DCS, UCS

Exceptions

SP5-998-001 clears most of the settings and counters stored in the NVRAM on the BICU (the values return to their default values). However, the following settings are not cleared:

• SP5-807 (Area Selection)
• SP5-811-001 (Serial Num Input [Code Set])
• SP5-811-003 (Serial Num Input [ID2 Code Display])
• SP5-812-001 (Service TEL [Telephone])
• SP5-812-002 (Service TEL [Facsimile])
• SP5-907 (Plug & Play)
• SP7 (Data Log)
• SP8 (History)

Use SP5-998-001 after you have replaced the BICU NVRAM or when the BICU NVRAM data is corrupted. When the program ends normally, the message "Completed" is displayed.
When you have replaced the controller NVRAM or when the controller NVRAM data is corrupted, use SP5-801-001. The message is the same as the basic machine.

Memory Clear Procedure

1. Print out all SMC data lists.
2. Do SP5-998-001.
3. Press the OK key.
4. Select "Execute." The messages "Execute?" followed by "Cancel" and "Execute" are displayed.
5. Select "Execute."
6. When the program has ended normally, the message "Completed" is displayed. If the program has ended abnormally, an error message is displayed.

8. Adjust the printer and scanner registration and magnification (* "Copy Adjustment" in the chapter "Replacement and Adjustment").
9. Refer to the SMC lists, and enter any values that differ from the factory settings. Double-check the values for SP4-901.
10. Adjust the standard white level (SP4-428).
11. Initialize the TD sensor (SP 2-214).
