AGFA Avantra 36/44 Service Manual page 82

The supply cassette consists of:
• Cassette housing
• Tension roller
• Two hub and spindle assemblies
Refer to Figure 2-20.
The cassette housing opens in the center to facilitate the loading of media. The ten-
sion roller mounts on the upper half of the housing and keeps the media tightly
wrapped on its core, while the media is either being pulled out or rewound.
Two hub and spindle assemblies, one placed at each end of the cassette housing,
provide support for the media roll and the necessary user width adjustment.
Machined grooves every inch on the spindles provide a detent position for the hubs
to accurately and repeatedly locate the media roll in the cassette. One of the hub
and spindle assemblies has a gear located at the end, which when loaded into the
system, engages the supply cassette motor and gear to facilitate the rewinding of
the media from the drum back onto the media core. This eliminates unnecessary
media waste when unloading and changing to an alternate supply cassette.
