2-36 Mechanism Configuration and Operating Principles Rev. A
Operation panel and cover open sensor circuits
There are five LEDs on the operation panel (POWER, ERROR, RECEIPT OUT, JOURNAL OUT,
and SLIP) and two buttons (RECEIPT FEED, and JOURNAL/SLIP FEED). The cover open
sensor uses a photosensor.
These parts are mounted directly on the switch PCB unit, which is linked to the main PCB
assembly via connectors (CN8).
