HISTORY
First mass production
Corrects the following:
When scanning originals with the DF in Mixed
Original or Double-Sided Original modes, a
noise can sometimes be heard when the
original is output to the reverse table. To ensure
this noise does not occur, bit4 of the ADF
controller DIPSW has been modified so that the
reverse paper exit speed can be adjusted as
follows:
ADF DIPSW bit4 OFF: 4310pps (pulses per
sec.)
This bit is set at the factory, depending on
which setting produces less noise (most
cases: set to ON). However in the field, if a
noise occurs after replacing the motor or
ADF controller, this can be eliminated or at
least minimized by changing the bit to the
opposite setting (e.g. ON → → → → OFF).
Sometimes with Mixed Original Size mode, the
motor remains on and/or a DF jam occurs.
