If an original fed out of the rear exit is longer than 450 mm
(18"), the rollers will stop and hold the trailing edge. The
operator must pull the original out and remove it from the
tray.
If the original is shorter than 450 mm, the rollers feed the
original out to the rear original exit tray.
This feature prevents long originals from falling off the rear
exit tray.

This feature can be switched off and on with SP4975. The default setting is on
(the rollers do not release the trailing edges of originals longer than 450 mm).
This SP must be turned off if a rear original stacker is used. Otherwise, only
one original can be fed at a time.
The machine does not hold the trailing edge of copies.
