Original Size Detection
„
Original length and width are read when the original
passes the skew correction sensor
Service manual, section 6.4.8
ˆ
The original width sensors cannot detect the width until the original has passed the
entrance roller.
ˆ
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 skew correction sensor and clock pulse
counts from leading edge to trailing edge.
ˆ
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.
¾
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.
¾
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.
¾
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.
Writer’s note: If this SP is likely to be useful, I recommend testing this in
the class, using the paper sizes that you will encounter in your market. The
description in the manual could be incorrect (not sure about this). 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. Test the machine in class and find out what
actually happens.
ˆ
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.
