CHAPTER 2 OPERATIONS AND TIMING
Conditions of detection
At time of pre-reversal, the separation sensor
remains on although an original is assumed
to have been moved over a specific distance
(169 mm) after the reversal sensor has de-
tected its leading edge.
At time of pre-reversal, the pre-registration
roller paper sensor remains on although an
original is assumed to have been moved over
a specific length (about 120 mm) after the
trailing edge of an original has moved past
the separation sensor.
At time of pre-reversal, the post-registration
roller paper sensor remains on although an
original is assumed to have been moved over
a specific length (about 50 mm) after the
trailing edge of an original has moved past
the pre-registration roller paper sensor.
At time of pre-reversal, the reversal sensor
remains on although an original is assumed
to have been moved over a specific distance
(about 100 mm) after its trailing edge has
moved past the post-registration roller sen-
sor.
At time of reversal, the reversal sensor de-
tects an original after an original has been
made to arch and then moved over a specific
distance (original length x 1.5; approx.).
At time of reversal, the pre-registration roller
sensor does not detect an original although
an original is assumed to have been moved
over a specific distance (about 197 mm) after
it has been made to arch (S1 area).
At time of reversal, the pre-registration roller
paper sensor remains on although an original
is assumed to have been moved over a spe-
cific distance (original length x 1.5) after the
pre-registration roller paper sensor has de-
tected its leading edge.
