The process is repeated until all 10 film frames have been processed and transported to the Storage
Chamber. The 10 film frames and the dark slide will now cause the Full ChamberLink to close the Full
Chamber contacts of the Logic Switch (Figure 2-28), preventing further operation until the chamber is
emptied. The Full Chamber Switch is also used to detect film jams. During each normal cycle, the Full
Chamber Switch is closed and remains closed until the end of the cycle, when it opens.
Should a jam occur, the Chamber Pick will be unable to retract, in turn preventing the Full Chamber switch
from reopening. The camera logic then interprets this as a jam, triggering audible and LED alarms.
