FAX SC CODES

7.2 FAX SC CODES

7.2.1 OVERVIEW

When the FCU detects a Fax SC Code condition other than SC1201 and SC1207,
it resets itself automatically (default setting). This initializes the FCU without
erasing files in the SAF memory or resetting the switches.
NOTE: For details on Fax SC Codes 1201 and 1207, refer to the following
sections.
If bit 7 of System Switch 1F is changed to "1", when the FCU detects a Fax SC
Code condition, 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.
• Remove the rear cover, and press SW2 on the FCU.
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.

7.2.2 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 SW1 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

7.2.3 SC1207

This is the same as SC1201 except the error location is the SRAM on the EXFUNC
board.
The possible causes are:
• SRAM backup battery defect, or SW1 on the EXFUNC board is at the "OFF"
position.
• SRAM on the EXFUNC has a physical defect.
• The EXFUNC connection was loose.
