For information on power requirements, power consumption, dimensions, weight, and other specifications that are
common to all features of the machine, refer to page 8-2 of "Operation manual (for general information and copier
operation)".
*1 Transmission speed is for an A4 or 8-1/2"x11" document with approximately 700 characters at standard
resolution (8x3.85 lines/mm) sent in high speed mode (33.6 kbps (JBIG) or 14.4 kbps (MMR)). This is only the
time required to transmit the image information; the time required to send protocol signals is not included.
Actual transmission times will vary depending on the contents of the document, the receiving machine type,
and telephone line conditions.
