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. This leads to decrease the server load and to reduce the time lag during transferring the mail.

  • Requirements for destination server:
    • Supports with Internet FAX (as a destination of Internet FAX)
    • Can receive mails (as a destination of mail)
    • Is installed in the same LAN as this machine
    • Supports with the SMTP mail reception, and the reception protocol is set to SMTP

    • Set the port number for [SMTP server] to “25” to enable this feature.
    • If the sender server sends an Internet FAX or a mail using this feature, the SMTP authentication is disabled even if the server sets it.
    • Using this feature, error notification mail will not be sent even if the mail is not properly received.
    • Also, error mail will not be sent even if the mail is not sent properly.
    • This feature refers to A records (not supported with MX records).

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
