■ Buffer Operation
1. The trailing edge of the paper fed by the host machine is detected by the input sensor (PS101). The paper is fed for a specified
amount where it stops.
2. The flapper motor (M104) is driven to switch the buffer/saddle inlet flapper. The pre-processing/buffer motor (M102) is driven
in reverse to feed the paper to the buffer path unit. The paper trailing edge is detected by the buffer sensor (PS103), and the
paper is fed a specified amount where it stops.
