SERVICE PROGRAM MODE

MEMORY CLEAR

Basic Machine and MFP Machine

The basic machine (the machine without the optional controller box) stores all the
data in the NVRAM on the BICU. The data is cleared by SP5-801-002 (for
exceptions, see "Exceptions").
The MFP 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").

SP5-801-002 (basic machine) and SP5-998-001 (MFP machine) 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 SP5-802-002 (basic machine) or SP5-998-001 (MFP machine) 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.
