2. Operational descriptions
A. Paper transport section
Paper is fed from each paper feed section and transported to the
resist roller by the transport rollers. ON/OFF control of each trans-
port roller is made by the paper transport clutch. The resist roller
controls the relative positions of transported paper and the transfer
image. The resist roller is driven by the transport motor. The rela-
tive positions of paper and the transfer image are determined...
