Figure 2-14 Take-up cassette.
–Take-up cassette. –Six cover screws. –Core. –Clutch adjustment screw.
In order to accept media, the core is driven enough to open the counter-weight
gap. A reflective optical sensor is located in the take-up area. This sensor operates
during the drive sequence and signals the exact point that aligns the core gap to the
entrance chute.
The core is driven by an attached friction wheel, which is engaged against a spring-
loaded, electrically interlocked DC gear motor that resides on the take-up platform.
Reflective tape, which attaches to the bottom of the take-up cassette, covers a sen-
sor on the take-up platform when the cassette is installed into the system. This
informs the system when a take-up cassette is in position for system operation.

2.14.3 Media Punch/Clamp Assembly

The media punch makes registration holes in the media. Refer to Figure 2-15.
The punch assembly achieves high accuracy by punching the media within the
imaging drum, then imaging the media without any intervening media movement.
The head punch assembly is located on the top (take-up side) of the page. The tail
punch assembly is located at the bottom (supply side). These two punch assem-
blies are individually selectable for activation from the operator's control panel.
