FAX-L1000 Chapter 1: Safety and Precautions
Jumper plug caution
The lithium battery backup function works when jumper plug JP 2 on the
SCNT board is shorted by a jumper plug. This means that registered data will
be erased when the power cord is disconnected with the jumper plug removed.
Before removing the jumper plug, make sure that you print out all registered
data. The fax is shipped from the factory with the jumper pin shorted by the
jumper plug.
Cautions when replacing the SCNT board
Before replacing the SCNT board during servicing, make sure that you print
out all registered data.
The SCNT board in the service parts is not provided with a jumper plug (JP2),
in order to prevent battery discharge. Therefore, use the jumper provided on the
SCNT board that is to be replaced.
When you turn the power on after replacing the SCNT board, “DELETE
FILE PRESS SET KEY” will be displayed. When you press the Set button
with “DELETE FILE PRESS SET KEY” displayed, the image management
data in the SRAM is cleared. Then “DATA ERROR PRESS SET KEY” will
be displayed. When you press the Set button with “DATA ERROR PRESS
SET KEY” displayed, the user and service data in SRAM will be initialized
to their original factory settings. Next, register the data from the old SCNT
board, referring to the print out.
Lithium battery replacement cycle
The life of the lithium battery is five years with the power turned off.
However, when the power is ON, there is no discharge of power from the
lithium battery, so the actual life of the battery will be over 5 years.
When the lithium battery reaches the end of its life, “DELETE FILE PRESS
SET KEY” or “DATA ERROR PRESS SET KEY” will be displayed after a
power interruption, or when the power is turned on. If this happens, replace
the lithium battery.
When you replace the lithium battery, all the backed up data will be erased
and there will be nothing to print out.
When you turn the power on after replacing the lithium battery, “DELETE
FILE PRESS SET KEY” will be displayed. When you press the Set button
with “DELETE FILE PRESS SET KEY” displayed, the image management
data in the SRAM is cleared. Then “DATA ERROR PRESS SET KEY” will
be displayed. When you press the Set button with “DATA ERROR PRESS
SET KEY” displayed, the user and service data in SRAM will be initialized
to their original factory settings.
