5. Sub Scan Resolution Conversion

Standard: The machine feeds the document in 7.7 line/mm steps, and scans
it in accordance with the setting of scanner bit switch 00, bit 4. A scanning
resolution of 3.85 lines/mm means that the machine scans once every two
motor steps.
Immediate tx/ Copying
Scanning to memory

The scanned lines are transmitted without any conversion.
Fine: The machine feeds and scans the document in 15.4 line/mm steps.
The scanned lines are transmitted without any conversion. In memory trans-
mission, if the other terminal cannot receive a message at Fine resolution,

6. Stamping

FDU
FCE
FCIP
The original always stops at the stamping position after the page was trans-
mitted (immediate transmission) or stored (memory transmission)
successfully.
If the Stamp LED is turned on, the cpu drops the voltage at CN18-5 for 500
ms to activate the stamper solenoid [A]. Then the original is fed out of the
scanner.
If the Stamp LED is turned off, the machine feeds out the original without
stamping.
