Fax Sc Codes - Ricoh B039 Service Manual

4.2 FAX SC CODES

4.2.1 OVERVIEW
If bit 7 of System Switch 1F is at the default setting, when the FCU detects a Fax
SC Code condition other than SC1201, it resets itself automatically. This initializes
the FCU without erasing files in the SAF memory or resetting the switches.
NOTE: For details on Fax SC Code 1201, refer to the following section.
If bit 7 of System Switch 1F is changed to "1", when the FCU detects any Fax SC
Code condition (not only SC1201), it displays the code on the display and stops
working until the fax unit is initialized using one of the following methods:
• Hold down the "#" and "*" keys for more than 10 s.
• Turn off the main power switch and turn it back on.
The fax unit cannot make automatic service calls in reaction to a Fax SC Code,
because the fax unit cannot make fax communications in fax SC Code conditions.
4.2.2 SC1201
When the FCU detects an unrecoverable error in the SRAM, which requires a
complete SRAM initialization, the fax unit displays this SC Code and stops.
There is no way to recover from this error condition without a complete SRAM
initialization (all the user and service programmed data will be erased).
The possible causes are:
• SRAM backup battery defect, or TB3 on the FCU is at the "OFF" position
• SRAM on the FCU has a physical defect
• Flash memory card or data copy tool connection was loose
