When mail is sent, there is no negotiation with the 
receiving machine at the destination, so the 
sending machine cannot make a selection for the 
receiving capabilities (original width setting) of the 
receiving machine. The original width selected 
with this switch is used as the RX machine’s 
original width setting, and the original is reduced 
to this size before sending. The default is A4. 
If the width selected with this switch is higher than 
the receiving machine can accept, the machine 
detects this and this causes an error.

When on (set to “1”), the machine converts  millimeters to inches for sending mail. 
There is no switch for converting inches to millimeters.  
Unlike G3 fax transmissions which can  negotiate between sender and receiver to 
determine the setting, mail cannot negotiate between terminals; the mm/inch 
selection is determined by the sender fax.

Images scanned in inches are sent in inches. 
Images scanned in mm are sent in mm. 
Images received in inches  are transmitted in inches.

Images scanned in mm are c onverted to inches. 
Images received in inches  are transmitted in inches.
