Refer to 6.4.3. READ SECTION for circuit descriptions.
**The CCD BOARD installed on the CCD UNIT is adjusted precisely in our production line.
Therefore, if the CCD board is reinstalled while making repairs, it must be readjusted after troubleshooting. (Refer to 3.3. CCD
ADJUSTMENTS.)
If the printout is correct while receiving test printing but incorrect while copying, the read section may be broken.This is caused by
the CCD UNIT or ASIC (IC501) [Digital board]. First, perform a SCAN CHECK to determine if the LED array lights. (Refer to 2.5
TEST FUNCTIONS.)
IC501 outputs the signal for the CCD UNIT correctly.But the
CCD UNIT doesn't output an analog image signal.
IC501 outputs the signal for the CCD UNIT correctly.But the
