  • Page 428 SIGNAL FLOW (6) PC Print The data input from the MCNT’s parallel I/F is input, through the IOGA5, to the DRAM using DMA. The input data is transferred to the DEC block in the IOGA5 using DMA. In the DEC block, the data is expanded in the 1-line raster buffer in the IOGA5. Then, the expanded data is sent to the video block in the IOGA5 in response to a 1-line syn- chronous signal.

    OUTLINE Functions When the Second Paper Feeder is installed with the OKIFAX 5750/5950 series facsimile transceiver, the Second Paper Feeder is connected to the facsimile by a connector. The Second Paper Feeder supplies paper automatically through the operation of pulse motor (hopping), which is driven by signals sent from CPU of the Second Paper Feeder under the control of the facsimile.

  • Page 537: Mechanism Description

    MECHANISM DESCRIPTION General Mechanism The Second Paper Feeder feeds the paper into the facsimile by receiving the signal from the facsimile, which drives the pulse motor inside the Second Paper Feeder, and this motion is transmitted to rotate the one-way clutch of the hopping frame assembly. The paper is delivered from the hopper into the facsimile through the turning of the hopping roller and feed roller.
