Original Size Detection
!
Original length and width are read when the
original passes the separation sensor
#
The original width sensors cannot detect the width until the original has passed
the entrance roller.
#
Some small sizes cannot be detected by the sensors (A5SEF, B6SEF, B6LEF),
because the sensor outputs for these sizes are identical (all sensors are off). In
this case, the length is detected using the separation sensor and clock pulse
counts from leading edge to trailing edge.
#
The machine cannot tell the difference between certain original sizes, such as
DLT (11 x 17”) and 11 x 15”. The machine assumes such originals are 11 x 17.
To change this, use SP 6016 and SP 5126.
$
North America: There are two sets of four sizes. To switch from the default
set to the other, input 120. The other set of four sizes will then be detected.
To change back again, input 0.
$
Europe: There are two sets of three sizes. To switch from the default set to
the other, input 7. The other set of three sizes will then be detected. To
change back again, input 0.
$
It is not possible to change just one of the settings. All three (or all four in
the case of N. America) must be changed at the same time.
Test this, using the paper sizes that you will encounter in your market.
The description in the manual could be incorrect. Perhaps you have to
enter a decimal number equivalent to the 0/1 settings of an 8-bit register.
Look at the accompanying file ‘SP6016-alternativemethod.doc’ for what
may actually happen.
#
The maximum length of an original in the ADF is 440 mm (17”). This can be
changed to 1260 mm (49.5”) with the Special Original function at the operation
panel.
#
In the scanner below the exposure glass, there are also some sensors, as in
previous models.
#
There are some differences between the Europe and North America versions

EU: Length sensor x 1, NA: Length sensor x 2
