Original Skew Correction - Ricoh B003 Service Manual

ORIGINAL FEED-IN MECHANISM

4.4.2 ORIGINAL SKEW CORRECTION

[C]
This mechanism is the same as the skew correction used by the registration roller
in the main machine.
The feed motor and the skew correction clutch control the skew correction roller.
Immediately after separation, the skew correction sensor [A] detects the leading
edge of the original. The feed belt [B] moves the paper slightly until it presses
against the skew correction roller [C] and buckles slightly to correct any skew.
4.4.3 REDUCING THE INTERVAL BETWEEN PAGES
After performing skew correction, the feed motor runs at a speed higher than its
original speed in order for the next original to catch up to the one ahead of it. This
reduces the gap between the leading edge of the next original with the trailing edge
of the one ahead.
When the leading edge of the original activates the interval sensor [A], the feed
motor slows to match the speed of paper transport.
