Fax Communication Features SM 131 B786 B786 Fax Option 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. ƒ When using the document server, the SAF memory is not used. ƒ The document is compressed with MMR and stored. ƒ Up to 9,000 pages can be stored. (1 file: Up to 1,000 pages) from the fax application. ƒ Only stored documents from the fax application can be transmitted. ƒ Scanned documents are given a name automatically, such as “FAX001”. But it is possible to change the file name, user name and password. ƒ Up to 30 files can be selected at once. ƒ The compression method of the fax application is different from the copy application. The storing time is longer than the copier storing. ƒ When selecting “Print 1st page”, the stored document will be reduced to A4 size. 5.4.3 INTERNET MAIL COMMUNICATION Mail Transmission This machine supports T.37 full mode. (ITU-, RFC232). The difference between T.37 simple mode and full mode is as follows.

Fax Communication Features B786 132 SM 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: [email protected] SMTP server address: gts.abcd.com In this case this feature destination e-mail address ([email protected]) is read as the SMTP server address gts.abcd.com and the transmissions bypass the SMTP server. Selectable Options These options are available for selection: ƒ 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. ƒ The requirements for originals (document size, scan width, and memory capacity) are the same as for G3 fax memory TX. ƒ The default compression is TIFF-F format.

The machine must be set up for SMTP mail delivery: User Tools> Facsimile Features> E-mail 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> E-mail Settings> SMTP RX File Delivery Settings). 3. If the “SMTP RX File Delivery Setting” is set to 0 to prohibit SMTP receiving, and if there is mail designated for delivery, then the machine responds with an error. (User
Fax Communication Features B786 134 SM Tools> Facsimile Features> E-mail 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: [email protected] Matches and is delivered. [email protected] Does not match and is not delivered. [email protected] Does not match and is not delivered. 2. Conditions ƒ The length of the Access Limit Entry is limited to 127 characters. ƒ 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. ƒ If the Access Limit Entry address is not registered, and if the incoming mail specifies a delivery destination, then the mail is delivered unconditionally. 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
Fax Communication Features SM 135 B786 B786 Fax Option 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 Blind carbon copy 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….

Receive confirmation of mail reception The other party’s machine will not respond to the request unless the two conditions below are met: ƒ The other party’s machine must be set up to respond to the confirmation request. ƒ The other party’s machine must support MDN (Message Disposition Notification). - Setting up the Receiving Party -
Fax Communication Features B786 138 SM 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 1. 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. 2. 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. 3. Receiving the Return Receipt Mail ƒ 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. ƒ When the return receipt reports an error, the journal is annotated with an “E” in the Result column. ƒ 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. ƒ 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
Fax Communication Features SM 139 B786 B786 Fax Option 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. Report Sample
