Side Registration Correction Operation Shift Operation
1) After the finisher controller board has detected the trailing edge of the paper at the inlet
sensor (PS3), the paper is fed on for 210mm and then the inlet roller disengage motor (M27)
drives and disengages the disengage roller friction roller. (Grounding performed when the
paper has been fed 38.2mm after the inlet sensor (PS3) goes OFF.)

2) When the finisher controller board has detected the trailing edge of the paper at the inlet
sensor (PS3), the feed motor (M2) begins to rotate forwards after a prescribed period. This
causes the roller inside the shift roller unit to begin to rotate.
3) The finisher controller board computes the side registration correction value from the side
registration detection results.
Then, once the trailing edge of the paper clears the inlet feed roller (*1), and based on
the computed side registration correction value, the side registration shift motor (M7) will
rotate either forwards or in reverse. In this way, the shift roller unit will move either forwards
or backwards, and the paper, nipped by the shift roller will be shunted either backwards
or forwards, as it is being fed through. As a result, the paper's side registration value is
corrected to the prescribed value.
*1
: When the paper is 297mm or less in the feed direction. For paper of 297mm or longer,
this timing is when the trailing edge of the paper enters the finisher inlet.
