For information on power requirements, power consumption, dimensions, weight, and other specifications that are 
common to all features of the machine, refer to operation manual for copier.

*1 Transmission speed is for an A4 (8-1/2" x 11") 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.

*2 Image memory can be expanded by installing the optional fax expansion memory (8 MB).
*3 The length varies depending on the scanning resolution and the width of the original. At "FINE" resolution, the maximum size 

is 297 mm (W) x 1000 mm (L) (11" (W) x 39.3" (L)). ("ORIGINALS" (p.9))

*4 Can only be used in Taiwan.
*5 Can only be used in Australia and New Zealand.
