Power Supply - Oce 3121 Technical & Service Manual

11 Power supply

The power for the sorter is supplied by the copier.
The 5V supply for the logic system is generated from 24V power. It is control-
led by the regulator on the tray control PBA.
The power to the Multitray will be cut when the copier's power is turned off or
the connection between the copier and the Multitray is disconnected. To back
up the data in the RAM (Q8) on the tray controller PCB, the Multitray is
equipped with a back-up power supply PCB whose capacitor is capable of sup-
plying power for about one hour.
