Booklet maker control of paper movement
●
When the leading edge of the paper has passed the inlet flapper, the intermediate-feed roller
and the crescent roller start to move the paper forward.
●
When the leading edge of the paper reaches the intermediate-feed roller, the feed-plate-contact
solenoid (SL4) causes the roller to contact the path bed and move the paper forward. When the
leading edge of the paper reaches the paper-positioning plate, contact is broken.
●
When the leading edge of the first sheet reaches the paper-positioning plate, the paper-
positioning-plate paper sensor (PI8) turns on. Subsequent sheets will not be checked because
the first sheet will still be over the sensor.
