COMMENTS
Change this bit to 1 when installing the PC-Fax
Expander.
1: The machine does not dial the PSTN access
code programmed in the PC-Fax application
during PC-Fax memory transmission.
This function becomes effective only when the PC
fax application dials using a Quick/Speed/Group
Dial stored in the fax machine.
The machine will not omit dialing the PSTN
access code when a destination number is
programmed manually.
Do not change the settings.
This function is effective for PC memory
transmission.
0: The pages stored in the SAF will be transmitted
from the machine.
1: All data is cleared when an error occurs.
However, if the SAF memory becomes full during
data storage, the setting of system bit switch 1E
bit 1 determines how data is treated.
This function is also effective for PC printing.
This bit determines the resolution unit used for PC
fax communication.
This is because the PC fax application cannot
automatically adjust the resolution unit.
This setting is also effective for PC scanning.
Do not change the settings.

troubleshooting.
