3.9 Stamp Operation

3.9.1 Outline (with the Stamp Unit-B1)

If the stamp function is selected in the FAX mode of the host machine, the stamp solenoid drive signal received from the ADF driver PCB drives the stamp solenoid
(SL1) to affix a stamp indicating that the document has been read or sent.
In the stamp mode, the feed speed is set to 260 mm/s after completion of document reading. The document stops when it has been fed 14.6 mm since detection of
tuning off of the delivery reversal sensor, where a stamp is affixed. The stamp solenoid drive time is 100 ms, and a stamp is affixed at the position which is about
10 mm away from the trailing edge of paper.
