FAX SC CODES

6.3 FAX SC CODES
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 SC Code conditions.
6.3.1 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
6.3.2 SC1202
When the FCU detects an unrecoverable error in the HDD control area of the
EXSAF SRAM, or if the HDD is replaced without initializing the SAF memory, the
fax unit displays this SC code and stops.
To recover from this error, do the following.
1. Disconnect the HDD from the EXSAF.
2. Initialize the SAF files using service mode function 07-2.
3. Connect the HDD again.
If the problem persists, replace the EXSAF.
