ed.1 21 Sorter 515
Outputs from the Tray Control PBA (2/2)
Communication with the copier
The sorter communicates with the copier in IPC communication mode, using
a communication IC.
As shown, the communication IC (Q11) on the Multitray’s tray controller PCB
and the copier’s communication IC exchange status signals and data, and such
exchanges are controlled by the microprocessor of each machine.
IPC communication uses communication ICs, freeing the copier’s microproc-
essor from some work loads.
Warning: If the self diagnosis function becomes activated because of a com-
munication error, turn off the copier’s power supply, detach the Multitray, and
then turn on the copier’s power supply. This way, the copier may be used for
making copies.
