G3 receive Mode
Figure A2.2.3 shows the G3 receive picture signal route
In the G3 mode, the high-speed picture signal arriving from the telephone line at L1 and L2 of NCU
passes through the transformer T1 and the amplifier and is input to the MODEM as “R” signal. After
demodulation by modem, the picture data is sent to CPU. The CPU performs the picture data
processing (decode) for this picture data and stores into the DRAM. Then, the stored picture data is
again written into DRAM (as a page memory) by the picture processing control of CPU. When the
data for one page has been stored in the DRAM/P-SRAM, the data is read out from the DRAM and
sent to IOGA. The picture data is converted into a signal data by the printer control of IOGA and
transferred to the LED print head for printing as HDATA 0/1.
