The data encoded and HDLC framed in PC is input to IOGA4 via the parallel I/F to be transferred to the DRAM under the control of DMA. The stored encoded data is output from DRAM to the MODEM under the control of IOGA4 (CPU).
  • Page 280 (13) G4 RX mode Figure A.4 (13/13) shows the signal route of this mode. The signal received from an ISDN line is transferred to the dual-port RAM (DPRAM) by the control of the CPU via the ISDN driver and ISDN controller of the G4N board. Notified of the existence of received G4 data by interruption, the IOGA4 (CPU) of the 46F board transfers the data from the DPRAM to the DRAM.

The surface potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the image signal.
  • Page 375 (5) Development The electrostatic latent image on the surface of the OPC drum is changed to a visible toner image by applying a toner to it. Development is performed in the contact part between the OPC drum and developing roller. The sponge roller negatively charges a toner and applies it to the developing roller.

A sheet of paper is placed on the surface of the OPC drum and the positive charge opposite to the negative charge of a toner is applied from the reverse side by the transfer roller.
