1. FAX COMMUNICATION FEATURES​

   1. MULTI-PORT​

      When the optional extra G3 Interface Unit is installed, communication can take place at the same time through the two or three lines at once.
      
      

      Option	Available Line Type	Available protocol Combinations
      Standard only	PSTN	G3
      Extra G3 Interface Unit (single)	PSTN + PSTN	G3 + G3
      Extra G3 Interface Unit (double)	PSTN + PSTN +PSTN	G3 + G3 +G3

   2. DOCUMENT SERVER​

      
      
      
      
      
      The base copier's scanner scans the original at the selected resolution. The IPU video processes the data and transfers it to the controller board.
      Then the controller stores the data in the page memory for the copier function, and compresses the data in MMR (by software) to store it in the HDD. If image rotation will be done, the image is rotated in the page memory before compression.
      For transmission, the stored image data is transferred to the FCU. The FCU decompresses the image data, then recompresses and/or reduces the data if necessary for transmission. The NCU transmits the data to the line.
      The documents can be stored in the HDD (Document Server) from the fax application. The stored documents in the document sever can be used for the fax transmission in many times. More than one document and the scanned document can be combined into one file and then the file can be transmitted.
      • When using the document server, the SAF memory is not used.
      • The document is compressed with MMR and stored.
      • Up to 9,000 pages can be stored (1 file: Up to 1,000 pages) from the fax application.
      • Only stored documents from the fax application can be transmitted.
      • Scanned documents are given a name automatically, such as "FAX001". But it is possible to change the file name, user name and password.
      • Up to 30 files can be selected at once.
        
        
        
        
        Fax Option Type 5002 (D629)
        
        • The compression method of the fax application is different from the copy application. The storing time is longer than the copier storing.
        • When selecting "Print 1st page", the stored document will be reduced to A4 size.
          

   3. INTERNET MAIL COMMUNICATION​

Mail Transmission

T.37 simple and full modes

This machine supports T.37 full mode. (ITU-T Recommendation, RFC2532). The difference between T.37 simple mode and full mode is as follows.

Function	T.37 Simple Mode	T.37 Full Mode
Resolution	200 x 100 200 x 200	200 x100 200 x 200 200 x 400 400 x 400 (if available)
RX Paper Width	A4	A4, B4, A3
RX Data Compression Method	MH	MH (default), MR, MMR,
Signals	Image data transmission only	Image data transmission, exchange of capability information between the two terminals, and acknowledgement of receipt of fax messages

Data Formats

The scanned data is converted into a TIFF-F formatted file. The fields of the e-mail and their contents are as follows:

Field	Content
From	Mail address of the sender
Reply To	Destination requested for reply
To	Mail address of the destination
Bcc	Backup mail address
Subject	From CSI or RTI (Fax Message No. xxxx)
Content Type	Multipart/mixed Attached files: image/tiff
Content Transfer Encoding	Base 64, 7-bit, 8-bit, Quoted Printable
Message Body	MIME-converted TIFF-F (MIME standards specify how files are attached to e-mail messages)

Direct SMTP Transmission

Internet Fax documents can be sent directly to their destinations without going through the SMTP server. (Internet Faxes normally transmit via the SMTP server.)

For example:

e-mail address:	gts@ricoh.co.jp
SMTP server address:	gts.abcd.com

In this case, this feature destination e-mail address (gts@ricoh.co.jp) is read as the SMTP server address "gts.abcd.com", and the transmissions bypass the SMTP server.

Fax Option Type 5002 (D629)



Selectable Options

These options are available for selection:

• With the default settings, the scan resolution can be either standard or detail. Inch-mm conversion before TX depends on IFAX SW01 Bit 7. Detail resolution will be used if Super Fine resolution is selected, unless Fine resolution is enabled with IFAX SW01.
• The requirements for originals (document size, scan width, and memory capacity) are the same as for G3 fax memory TX.
• The default compression is TIFF-F format.
• IFAX SW00: Acceptable paper widths for sending
• IFAX SW09: Maximum number of attempts to the same destination
  Secure Internet Transmission
  SMTP Authentication:
• User Tools> System Settings> File Transfer> SMTP Authentication POP Before SMTP:
• User Tools> System Settings> File Transfer> POP Before SMTP
  
  Mail Reception
  Three Types
  This machine supports three types of e-mail reception:
• POP3 (Post Office Protocol Ver. 3.)
• IMAP4 (Internet Messaging Access Protocol)
• SMTP (Simple Mail Transfer Protocol)
  
  
  
  • For details: Core Technology Manual – Facsimile Processes – Faxing from a PC – Internet/LAN Fax Boards – Mail Reception
    POP3/IMAP4 Mail Reception Procedure
    The machine automatically picks up e-mail from the server at an interval which is adjustable in the range 2 to 1440 min. in 1-minute steps:
• User Tools> System Settings> File Transfer> E-mail Reception Interval
  SMTP Reception
  1. The IFAX must be registered as an SMTP server in the MX record of the DNS server, and the address of the received mail must specify the IFAX.
  2. To enable SMTP reception: User Tools> System Settings> File Transfer> Reception Protocol
     • Even if the MX record on the DNS server includes the IFAX, mail cannot be received with SMTP until SMTP reception is enabled:
     • However, if SMTP reception is selected and the machine is not registered in the MX record of the DNS server, then either IMAP4 or POP3 is used, depending on the setting: User Tools> System Settings> File Transfer> Reception Protocol
     Mail Delivery Conditions: Transferring Mail Received With SMTP
  1. The machine must be set up for SMTP mail delivery:
     • User Tools> Facsimile Features> Reception Settings> SMTP RX File Delivery Settings
  2. If the user wishes to limit this feature so that the machine will only deliver mail from designated senders, the machine's "Auth. E-mail RX" feature must be set (User Tools> Facsimile Features> Reception Settings> SMTP RX File Delivery Settings).
  3. If the "SMTP RX File Delivery Setting" is set to “Off” to prohibit SMTP receiving, and if there is mail designated for delivery, then the machine responds with an error. (User Tools> Facsimile Features> Reception Settings> SMTP RX File Delivery Settings)
  4. If the quick dial, speed dial, or group dial entry is incorrect, the mail transmission is lost, and the IFAX issues an error to the SMTP server and outputs an error report.
     Auth. E-mail RX
  In order to limit access to mail delivery with IFAX, the addresses of senders must be limited using the Access Limit Entry. Only one entry can be registered.
  1. Access Limit Entry
  For example, to limit access to @IFAX.ricoh.co.jp:
  
  

  gts@IFAX.ricoh.co.jp	Matches and is delivered.
  gts@IFAX.abcde.co.jp	Does not match and is not delivered.
  IFAX@ricoh.co.jp	Does not match and is not delivered.

  1. Conditions
     • The length of the Access Limit Entry is limited to 127 characters.
     • If the Access Limit Entry address and the mail address of the incoming mail do not match, the incoming mail is discarded and not delivered, and the SMTP server responds with an error. However, in this case an error report is not output.
     • If the Access Limit Entry address is not registered, and if the incoming mail specifies a delivery destination, then the mail is delivered unconditionally.
  Fax Option Type 5002 (D629)
  
  Handling Mail Reception Errors
  Abnormal files
  When an error of this type occurs, the machine stops receiving and commands the server to erase the message. Then the machine prints an error report and sends information about the error by
  e-mail to the sender address (specified in the "From" or "Reply-to" field of the message). If there is an incomplete received message in the machine memory, it will be erased.
  The machine prints an error message when it fails to send the receive error notification after a certain number of attempts.
  The following types of files are judged to be abnormal if one or more of the following are detected:
  1. Unsupported MIME headers. Supported types of MIME header
     
     

     Header	Supported Types
     Content-Type	Multipart/mixed, text/plain, message/rfc822 Image/tiff
     Charset	US-ASCII, ISO 8859 X. Other types cannot be handled, and some garbage may appear in the data.
     Content-Transfer- Encoding	Base 64, 7-bit, 8-bit, Quoted Printable

     
     
  2. MIME decoding errors
  3. File format not recognized as TIFF-F format
  4. Resolution, document size, or compression type cannot be accepted
     Remaining SAF capacity error
  The machine calls the server but does not receive e-mail if the remaining SAF capacity is less than a certain value (the value depends on IFAX Switch 08. The e-mail will be received when the SAF capacity increases (for example, after substitute reception files have been printed). The error handling method for this type of error is the same as for "Abnormal files".
  If the capacity of the SAF memory drops to zero during reception, the machine operates in the same way as when receiving an abnormal file (refer to "Abnormal files" above).
  Secure Internet Reception
  To enable password encryption and higher level security: User Tools> System Settings> File Transfer> POP3/IMAP4 Settings> Encryption (set to "On")
  
  Transfer Request: Request By Mail
  For details: Core Technology Manual – Facsimile Processes – Faxing from a PC – Internet/LAN Fax Boards – Transfer Request
  The fields of the e-mail and their contents are as follows:
  
  

  Field	Content
  From	E-mail address of the requesting terminal
  To	Destination address (Transfer Station address)
  Bcc	Backup mail address
  Subject	From TSI (Fax Message No. xxxx)
  Content-Type	Multipart/mixed Text/Plain (for a text part), image/tiff (for attached files)
  Content-Transfer-Encoding	Base 64, 7-Bit, 8-bit, Quoted Printable
  Mail body (text part)	RELAY-ID-: xxxx (xxxx: 4 digits for an ID code) RELAY: #01#*X#**01….
  Message body	MIME-converted TIFF-F.

  
  Fax Option Type 5002 (D629)

    Fax Option Type 5002 (D629)
    
    Message Disposition Notification (MDN)
    For details: Core Technology Manual – Facsimile Processes – Faxing from a PC – Internet/LAN Fax Boards – E-mail Options
    The network system administrator can confirm whether a sent mail has been received correctly or not. This confirmation is done in four steps.
    1. Send request for confirmation of mail reception. To enable or disable this request (known as MDN): TX Mode> Reception Notice
    2. Mail reception (receive confirmation request)
    3. Send confirmation of mail reception
    4. Receive confirmation of mail reception
       The other party's machine will not respond to the request unless the two conditions below are met:
• The other party's machine must be set up to respond to the confirmation request.
• The other party's machine must support MDN (Message Disposition Notification).
  • Setting up the Receiving Party -
    The receiving party will respond to the confirmation request if:
    1. The "Disposition Notification To" field is in the received mail header (automatically inserted in the 4th line in the upper table on the previous page, if MDN is enabled), and
    2. Sending the disposition notification must be enabled (User Parameter Setting SW21 (15 [H]) Bit 1 for this model). The content of the response is as follows:
       

    Normal reception:	"Return Receipt (dispatched)" in the Subject line
    IFAX SW02 (Bit 2, 3)	"Return Receipt (displayed)" in the Subject line
    Error:	"Return Receipt (processed/error)" in the Subject line

    Handling Reports
  • Sending a Request for a Return Receipt by Mail -
    After the mail sender transmits a request for a return receipt, the mail sender's journal is annotated with two hyphens (--) in the Result column and a "Q" in the Mode column.
  • Mail Receipt (Request for Receipt Confirmation) and Sending Mail Receipt Response -
    After the mail receiver sends a response to the request for a return receipt, the mail receiver's journal is annotated with two hyphens (--) in the Result column and an "A" in the Mode column.
  • Receiving the Return Receipt Mail -
• After the mail sender receives a return receipt, the information in the mail sender's journal about the receipt request is replaced, i.e. the journal is annotated with "OK" in the Result column.
• When the return receipt reports an error, the journal is annotated with an "E" in the Result column.
• The arrival of the return receipt is not recorded in the journal as a separate communication. Its arrival is only reported by the presence of "OK" or "E" in the Result column.
• If the mail address used by the sender specifies a mailing list (i.e., a Group destination; the machine sends the mail to more than one location. See "How to set up Mail Delivery"), the Result column of the Journal is updated every time a return receipt is received. For example, if the mailing list was to 5 destinations, the Result column indicates the result of the communication with the 5th destination only. The results of the communications to the first 4 destinations are not shown.
  Exceptions:
  If one of the communications had an error, the Result column will indicate E, even if subsequent communications were OK.
  If two of the communications had an error, the Journal will indicate the destination for the first error only.

        1. PAPER FEED MECHANISM​

           
           
           
           
           This machine uses the FRR paper feed system (paper feed roller [E], separation roller [H], pick-up roller [G]).
           When the right door is closed, the tray lift motor raises the tray to the position where the top of the paper stack in the tray interrupts the tray lift sensor [D]. The paper feed motor switches on, then the pick-up solenoid [C] switches off and the pick-up roller drops onto the top of the stack of paper. The paper feed clutch transfers drive to the paper feed roller [E], pick-up roller [G] and separation roller [H].
           The rotating pick-up roller lowers and feeds the first sheet when it contacts the top of the stack. The separation roller [H], in contact with the feed roller, only allows one sheet out of the tray.
           As soon as the paper feed sensor [F] detects the leading edge of the paper, it switches off the pick-up solenoid which raises the pick-up roller. The feed roller feeds the sheet to the registration roller in the main machine through the relay roller .
           This process is repeated for each sheet.
           The paper feed sensor [F] detects "JAM7" and the relay sensor [A] detects "JAM58".

           The lift motor [A] controls the vertical position of the tray through the timing belts .
           
           Tray lifting conditions
           When the tray lift sensor [C] turns off in the following conditions, the tray lift motor raises the tray bottom plate until the tray lift sensor [C] turns on again.
           
        
        
     
     
  
  [*]Just after the main switch is turned on
  [*]During copying
  [*]Just after the tray cover is closed
  [*]Just after leaving the energy saving mode
  
  Tray lowering conditions (Paper supply position)
  In the following conditions, the tray lift motor lowers the tray until the stack sensor [D] turns on (this is the correct tray position for supplying paper).
  [*]Just after the paper end sensor turns on
  [*]Just after the down switch is pressed by the user
  
  Tray lowering conditions (Full-down position)
  In the following condition, the tray lift motor lowers the tray until the lower limit sensor [E] turns on (this is the correct tray position for adding 500 sheets of paper after installing the first stack of paper in the LCT tray).
  [*]Just after the down switch [F] is pressed for 3 seconds or more when the tray is at the paper supply position.
  

1. PAPER HEIGHT AND END DETECTION​

Paper Height

The amount of the paper in the tray is detected by combination of high (1)/low (0) outputs from three sensors (paper height sensor 1 [A], 2 , 3 [D] and sub paper height sensor [C]).

Amount of paper	PH S-1	PH S-2	PH S-3	Sub PH S	Indicator on the operation panel
100%	0	0	0	0	Four lines
70%	0	0	1	-	Three lines
0	0	0	1
30%	0	1	-	-	Two lines
10%	1	-	-	-	One line
End	-	-	-	-	No line

0: No interruption (low), 1: Interruption (high), -: No checking PH S: Paper Height Sensor



Paper End

The paper end sensor [E] monitors the light reflected by each sheet on top of the stack.

When the last sheet feeds, the cutout [F] is exposed, and the paper end sensor receives no reflected light from below because there is no paper. As a result, this signals paper end.
