1.function
The image processor PCB has the following functions.
Control Panel Control Block
The control panel control block receives the state of control keys while sending/receiving data in serial communication with the control IC of the control panel PCB.
Also, it sends LED and LCD signals to the control panel PCB.
Image Processing Control Block
- It subjects the digital image data from the analog processor PCB to enlargement/reduction processing, smoothing, and other image processing, thereby converting
it to 600x600-dpi image signals (VD0, VD01*, VDO2, VDO2*).
- It converts the analog image data from fax communication into 600x600-dpi image signals (VD0, VD01*, VDO2, VDO2*).
- It uses a horizontal sync signal (BD0*) as a trigger to send image signals (VD0, VD01*, VDO2, VDO2*) to the laser unit.
Smoothing
The 600 x 600-dpi image data from the PC is converted into image data equivalent of 1200 x 600 dpi.
Sensor Detection
It detects the state of each sensor of the reader unit and the ADF.
ESS Control
It controls the ESS function used to reduce the power consumption while the machine isin standby state.
Memory Storage
Image data is stored in SDRAM, and is retained for about 1 hr even after the power is removed by the work of the super capacitor mounted on the modem PCB.
The system software and various data (e.g., user data, service data) are held by flash ROM.
SEND Function (if equipped with SEND functions.)
The SEND function uses a network to send image scanned by the reader unit to an external device.
Speaker Control (if equipped with fax functions.)
It turns on/off or control the volume of the error sound, key sound, and line monitor sound generated by the speaker.
MEMO:
The volume of the line monitor or the sound of the key sound or the error sound is adjusted in user mode.
