Function
Adjusts the original cut length in Synchro
Cut mode at 1189 mm.
Insert the 1189 mm length original five times
(this number displayed on the copy number
indicator can be changed : 1 to 10). If the
actual original length is different from the
standard length, input the following value in
the cut length indicator before inserting the
original:
Actual Length - Standard Length
Then the machine automatically calculates
the correction value. The data is overwritten
on SP#-39.
Adjusts the synchro cut length when a 297
mm original is used. Increasing the number
will shorten the paper cut length.
Adjusts the synchro cut length when a 1,189
mm original is used. Increasing the number
will shorten the paper cut length.
Displays the real time light sensor output
voltage.
In this mode, the PTL, main motor, QL and
the bias voltage for non-image areas can be
turned on and off using the Copy Media key.
Translucent paper = ON
Translucent Film = OFF
Even if the SP mode is canceled, the
voltage is displayed during the stand-by
condition or copy cycling.
To release this condition, turn the main
switch off and on.
Normally, an original cannot be inserted
from the rear side in Synchro-cut mode. If 1
is selected in this mode, an original can be
inserted from the rear side even if Synchro-
cut mode is selected. This mode cannot be
used with the trailing edge margin function.
In this mode, the copy will be 194 mm longer
than the original (A252 copier only).
