4.2.9 MEMORY ALL CLEAR (SP5-801)

NOTE: Memory All Clear mode resets all the settings and counters stored in the
NVRAM to the defaults, except for the following:
• Electrical total counter value (SP7-003)
• Machine serial number (SP5-811)
• Plug & Play brand name and production name setting (SP5-907)
• Some SBU settings (SP4-904-3, SP4-904-4, SP4-906, SP4-909)
Normally, this SP mode should not be used. This procedure is necessary only after
replacing the NVRAM, or when the copier malfunctions because the NVRAM is
damaged.

NOTE: Be sure to print out all the lists. If the NVRAM data upload was not
completed, it is necessary to change the SP mode settings by hand.
