SIGNAL FLOW
OKIFAX 5700/5900
A2 - 19
(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
synchronous signal. In the video block, image processing is performed for printing
and the resultant data is transferred to the LED head.
(7) PC Scanner
The analog data output from the image sensor is input to the MCNT-PCB to be
amplified by the amplifier. The amplified analog data is input to the scanner controller.
Next, the analog data is converted to digital data by the built-in A/D converter. The
digital data is corrected by the internal correction function, transferring binary-coded
data to the IOGA5 every eighth pixel. The data input to the IOGA5 is temporarily
written into the external DRAM (4 megabits x 16 bits). The written data is compressed
to TIF data by firmware, then written into the external DRAM again.
The written TIF data is sent to the MCNT’s parallel I/F through the IOGA5.
