Retrofit information
When installing the fax unit (machine code B383), it is not necessary to install the relay
harness shown in the below figure.
Relay Harness
The relay harness is packed with some of the August and September production lots of the
fax unit to fix a problem with the domestic version product. The harness is not mentioned
in the service manual.
The purpose of the relay harness was to stabilize +5VE power for the FCU by obtaining 5V
power directly from the interface unit power supply unit. This was necessary because
+5VE may drop and reset the CPU when the machine goes back to stand-by mode from
energy saver mode. However, even if the CPU is reset when the machine goes back to
stand-by mode from energy saver mode, no problem will appear with the overseas version
products. Instead, the relay harness may cause the documents stored in the fax memory
to disappear when the main switch is turned off and then on. This is because +5VE is
supplied slightly after +5V when the main switch is turned on, and the battery back up to
the memory is momentarily cut.
