3.1.2 Remote Copying
Remote copying occurs when another machine is selected as the printer on the control
panel; in it, image data read by the transmitting side is sent to the output side over the net-
work for printing.
At this time, the image data will be accompanied by such data as on the number of pages,
sorting/stapling instructions, and job information entered from the control panel.
All data is first written to the hard disk on the receiving side, and is read page by page un-
til all copying jobs are done for transmission to the printer unit of the output machine.
In other words, steps (12) through (16) are repeated inside the output machine until all
jobs are done. To make use of this function, the IP address of the output machine must be
registered making the following selections: user mode>copier mode>remote copy print.
REF.
If the auto acquisition function for IP address (DHCP, BOOTP, RARP) is
used in the user's network environment, the IP address of the machine is at
time forced to change, disabling the selected machine to serve as the printer
of remote copying.
