OKIOFFICE 44 Serv. Man., P/N 59276801
G3 Receive Mode
Figure A2.1.3 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.
