Powered Media Take-Up Cassette - AGFA Avantra 36/44 Service Manual

Section I: Imagesetter
2.14.1.4 Drive Rollers
The drive rollers load and unload media from either spindle A or B. They are
nipped by the spindle A/B gear motor, which is controlled by the spindle A/B sen-
sors.
2.14.1.5 Spindle A/B Sensors
These two sensors shut off the spindle A/B gear motor when the drive roller is
nipped to either A/B drive roller.
2.14.1.6 Supply Jam Sensor
The supply jam sensor detects media jams on the supply side. During media move-
ment, a wheel inside the sensor assembly moves and generates an output. If the
wheel doesn't move, a jam is reported to the control panel.
2.14.1.7 Supply Media Present Sensor
This sensor, which is located in the jam sensor assembly, informs the system when
media is loaded into the system. When the edge of the media passes the sensor
during a rewind, the sensor stops the supply drive and supply cassette rewind
motors.
