D. Copier/sorter communication
1) Outline
The copier and the sorter are exchanging the status signals by IPC
(communication IC).
This machine is provided with a new IPC and the old IPC communica-

Selection is made by the DIP switch (SW1) No. 6 on the sorter
controller PWB.

These signals are written into the RAM on the sorter controller PWB
and outputted according to the control signal from the CPU (Q1).
A serviceman cannot check if the status signal is properly transferred
or not. When, however, an error in signal transfer occurs, the self
diagnostics function of the copier functions to display the error code
on the operation section of the copier. (Code: F1-70)
