Removal of the Note Acceptor
The note acceptor positively locks into the System chassis. A spring-loaded release on the left side of the
acceptor engages a tab on the chassis to lock the acceptor in place. All connections between the note
acceptor and the rest of the System are made or broken automatically through a 14-pin connector on the
back of the note acceptor and its mate on the chassis.
To remove the acceptor:
1. Locate the spring release tab on the left side of the acceptor (Figure 3-2 Item 1).
2. Press the tab inward, toward the side of the acceptor and hold.
3. While maintaining pressure on the tab, pull the acceptor from the chassis.
To open the acceptor (after acceptor is removed from the chassis): Refer to Figure 3-2
1. Grasp and pull forward both acceptor cover release pins at the front corners of the acceptor cover,
and hold.
2. While maintaining pressure on the release pins, lift the acceptor cover.
Before replacing the acceptor, open the acceptor and check that no notes or other materials remain in the
note path. When inserting the acceptor into the chassis refer to the instructions: Insert Acceptor Module
into the chassis in Section 2, Installation.
Operational Notes - Cassette Stacker
The cassette stacker is a single-compartment unit, which can hold up to approximately 500 notes in
average, circulated condition. The cassette stacker does not contain any electronics or active drive
components. The acceptor provides drive to the stacker through gears located at the front and rear of the
stacker. See the previous sections, which describe these drive systems.
The internal drive mechanisms in the cassette stacker consist of a pinch roller set in the rear top of the
stacker, on either side of the note inlet, and a belt/screw mechanism located inside the front of the stacker
and along the bottom left of the stacker. Both mechanisms are driven through gears by motors in the
acceptor. The pinch rollers act as a drive-down for incoming notes. The belt/screw system operates the
stacker punch. See Figure 3-3.
The cassette stacker contains two positions for key locks. Keys can be removed only if both locks are in the
locked position. Both keys must be removed before the stacker can be seated in the chassis. The locks must
both be unlocked before the stacker top cover can be opened for emptying of notes. There is a screw inside
the cassette stacker that must be removed to disassemble the stacker. If this screw is not removed, it is not
possible to dismantle or open the cash box without serious damage.
Removal of the Cassette Stacker
The cassette stacker positively locks into the system chassis through the action of a spring-loaded release
lever located on the right side of the chassis (Figure 3-1). To remove the stacker, depress the lever, and then
pull the stacker out of the chassis.
