OKIDATA OF1050, Service Manual

Page: 200 / 449

The report data is read into DRAM (for OKIFAX 1050)/P-SRAM (for OKIFAX 2350/2450) in the sequence
the contents of data stored in the FLASH memory in advance under the control of CPU. The contents of
data is edited on the DRAM/P-SRAM. The data is read out from the DRAM/P-SRAM and sent to IOGA.
The data is converted into a serial data by the picture control of IOGA and transferred to the LED print
head for printing as HDATA.
3.6.07 Memory Transmission
This signal route describes the memory transmission used in broadcast mode, delayed broadcast mode,
etc.
The stored encoded data undergoes buffering, passes through CPU, MODEM and NCU and then sent out
to the telephone line.
3.6.08 Memory Reception
This signal route describes the memory reception used in no-paper mode, no-toner reception, confidential
mode, etc.
The encoded data received by the same route of (3) G3 receive mode undergoes the picture data
processing and stored into memory (DRAM for OKIFAX 1050/P-SRAM for OKIFAX 2350/2450) as such.
In case of printing, When the data for one page has been stored in the memory (DRAM/P-SRAM), the
data is read out from the memory and sent to IOGA. The printed data is converted into a serial data by the
printer control of IOGA and transferred to the LED print head for printing as HDATA.
