1. BIT SWITCHES - 2​

   
   
   
   • Do not adjust a bit switch or use a setting that is described as "Not used", as this may cause the machine to malfunction or to operate in a manner that is not accepted by local regulations. Such bits are for use only in other areas, such as Japan.

Default settings for bit switches are not listed in this manual. Refer to the System Parameter List printed by the machine.

1. 1. I-FAX SWITCHES​

      
      

      I-fax Switch 00 (SP No. 1-102-001)
      No	Function	Comments
      Original Width of TX Attachment File	This setting sets the maximum size of the original that the destination can receive. (Bits 3~7 are reserved for future use or not used.)
      0	A4	-
      1	B4
      2	A3
      3-6	Reserved
      7	Not used
      	0: Off (not selected), 1: On (selected) If more than one of these three bits is set to "1", the larger size has priority. For example, if both Bit 2 and Bit 1 are set to "1" then the maximum size is "A3" (Bit 2). 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.

      I-fax Switch 01 (SP No. 1-102-002)
      No	Function	Comments
      Original Line Resolution of TX Attachment File	These settings set the maximum resolution of the original that the destination can receive.
      0	200x100 Standard	0: Not selected 1: Selected If more than one of these three bits is set to "1", the higher resolution has priority. For example, if both Bit 0 and Bit 2 are set to "1" Then The Resolution is set for "Bit 2 200 x 400.
      1	200x200 Detail
      2	200x400 Fine
      3	300 x 300 Reserve
      4	400 x 400 Super Fine
      5	600 x 600 Reserve
      6	Reserve
      7	mm/inch
      	This setting selects mm/inch conversion for mail transmission. 0: Off (No conversion), 1: On (Conversion) 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. When this switch is Off (0):

      • 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 received in mm are transmitted in mm. When this switch is On (1):
      • Images scanned in inches are sent in inches.
      • Images scanned in mm are converted to inches.
      • Images received in inches are transmitted in inches.
      • Images received in mm are converted to inches.
        Fax Option Type 5002 (D629)
      
      
      

      I-fax Switch 02 (SP No. 1-102-003)
      No	Function	Comments
      0	RX Text Mail Header Processing
      This setting determines whether the header information is printed with text e-mails when they are received. 0: Prints only text mail. 1: Prints mail header information attached to text mail. When a text mail is received with this switch On (1), the "From" address and "Subject" address are printed as header information. When a mail with only binary data is received (a TIFF-F file, for example), this setting is ignored and no header is printed.
      1	Output from Attached Document at E-mail TX Error
      This setting determines whether only the first page or all pages of an e-mail attachment are printed at the sending station when a transmission error occurs. This allows the customer to see which documents have not reached their intended destinations if sent to the wrong e-mail addresses, for example. 0: Prints 1st page only. 1: Prints all pages.
      2-3	Text String for Return Receipt
      This setting determines the text string output for the Return Receipt that confirms the transmission was received normally at the destination.

      	00: "Dispatched" Sends from PC mail a request for a Return Receipt. Receives the Return Receipt with "dispatched" in the 2nd part: Disposition: Automatic-action/MDN-send automatically; dispatched The "dispatched" string is included in the Subject string. 01: "Displayed" Sends from PC mail a request for a Return Receipt. Receives the Return Receipt with "displayed" in the 2nd part: Disposition: Automatic-action/MDN-send automatically; displayed The "displayed" string is included in the Subject string. 10: Reserved 11: Reserved A mail requesting a Return Receipt sent from an IFAX with this switch set to "00" (for "dispatched") received by Microsoft Outlook 2000 may cause an error. If any setting other than "displayed" (01) causes a problem, change the setting to "01" to enable normal sending of the Return Receipt.
      4	Media accept feature
      This setting adds or does not add the media accept feature to the answer mail to confirm a reception. 0: Does not add the media accept feature to the answer mail 1: Adds the media accept feature to the answer mail. Use this bit switch if a problem occurs when the machine receives an answer mail, which contains the media accept feature field.
      5-6	Not Used
      7	Image Resolution of RX Text Mail
      This setting determines the image resolution of the received mail. 0: 200 x 200 1: 400 x 400 The "1" setting requires installation of the Memory Unit in order to have enough SAF (Store and Forward) memory to receive images at 400 x 400 resolution.

      I-fax Switch 04 (SP No. 1-102-005)
      No	Function	Comments
      0	Subject for Delivery TX/Memory Transfer
      This setting determines whether the RTI/CSI registered on this machine or the RTI/CSI of the originator is used in the subject lines of transferred documents. 0: Puts the RTI/CSI of the originator in the Subject line. If this is used, either the RTI or CSI is used. Only one of these can be received for use in the subject line. 1: Puts the RTI/CSI registered on this machine in the Subject line. When this switch is used to transfer and deliver mail to a PC, the information in the Subject line that indicates where the transmission originated can be used to determine automatically the destination folder for each e-mail.
      1	Subject corresponding to mail post database 0: Standard subject 1: Mail post database subject The standard subject is replaced by the mail post database subject in the following three cases:
      2-7	Not Used

      1. When the service technician sets the service (software) switch.
      2. When memory sending or delivery specified by F code is applied by the SMTP server
      3. With relay broadcasting (1st stage without the Schmidt 4 function).
         • This switch does not apply for condition 3) when the RX system is set up for memory sending, delivery by F-code, sending with SMTP RX and when operators are using FOL (to prevent problems when receiving transmissions).

      I-fax Switch 05 (SP No. 1-102-006)
      No	Function	Comments
      0	Mail Addresses of SMTP Broadcast Recipients
      Determines whether the e-mail addresses of the destinations that receive transmissions broadcasted using SMTP protocol are recorded in the Journal. For example: "1st destination + Total number of destinations: 9" in the Journal indicates a broadcast to 9 destinations. 0: Not recorded 1: Recorded

      I-fax Switch 08 (SP No. 1-102-009)
      No	Function	Comments
      0-7	Memory Threshold for POP Mail Reception
      This setting determines the amount of SAF (Store and Forward) memory. (SAF stores fax messages to send later for transmission to more than one location, and also holds incoming messages if they cannot be printed.) When the amount of SAF memory available falls below this setting, mail can no longer be received; received mail is then stored on the mail server. 00-FF (0 to 1024 KB: HEX) The hexadecimal number you enter is multiplied by 4 KB to determine the amount of memory.
