1999 CANON INC. CANON SUPER G3 FAX BOARD-F1 REV.0 MAY 1999 PRINTED IN JAPAN (IMPRIME AU JAPON)
C. Memory
The copier is equipped with two types of memories: the "page memory" is used to store images
(read or received) temporarily for processing in preparation for printing; and the "image memory" is
used to store transmission/reception image data after coding.
1. Page Memory
The page memory stores image data which has been processed for reproduction ratio, resolution,
image quality, and binary coding according to the selected fax mode. The page memory may be
expanded by 23 MB through installation of an accessory memory.
2. Image Memory
The image memory is as large as 32 MB (standard), and is used to store transmission/reception
image data after coding (equivalent of about 640 pages of Canon FAX Standard Chart No. 1). The
image memory may be expanded by 32 MB or 64 MB (32 + 32 MB) through installation of an
accessory memory.
The image memory is backed up by a lithium ion secondary battery, so that its contents may be
retained in the event that the copier loses its power because of a power shortage.
When the image memory becomes full during memory transmission or reading operation, the
mode will automatically switch to direct transmission. (See "Processing in a Memory Full
Condition.")
Caution:
Take note of the following when expanding the image memory:
1. Generate output of the contents of the existing memory.
2. Turn SW2 on the FAX Board off to deprive the image memory of power.
3. Install the additional memory.
4. After the work, turn on SW2 (i.e., slide it to the left).
