Canon iR4570 Series Service Manual page 717

Cause
There is a shortage of memory, not permitting
transmission.
# 701
The group ID set when the job was introduced
no longer exits. Or, the password has been
changed.
# 702
The memory is full, not permitting
transmission.
# 703
The memory image area is full, not permitting
further writing.
# 704
An error has occurred while an attempt is made
to obtain address information from the address
book.
# 705
The image data size is in excess of the upper
limit imposed on transmission data size set in
user mode, thus causing suspension of
transmission.
# 706
An address table is being imported from or to
the remote UI; or, a different transmission
component is being used.
# 711
All memory of the Box is used.
Remedy
1. Decrease the resolution, and try once again.
2. Remove unnecessary files to increase
available space.
Type in the correct group ID or the ID No.
(using the keypad); then, start over.
1. Wait a while. Try again until the ongoing
transmission of a job ends.
2. Try not to transmit to too many addresses at
once; rather, try dividing the address into
smaller groups.
1. Wait a while. Try transmitting after the
ongoing transmission of a job ends.
2. Remove files from the Box; if the operation
still fails to return to normal, turn off and then
back on the main power.
Check the settings of the address, and try once
again; if the operation is still not normal, try
turning off and then back on the main power.
Try changing the upper limit imposed on
transmission data size as part of the
communication control settings of system
control settings (user mode). When selecting
low resolution mode or using i-fax, try
decreasing the number of images to send at one
time so that the transmission will not be in
excess of the upper limit imposed on transfer
data size.
Start over once again.
Delete files from the Box.
