NOTES:
*A: This operation is performed when there is an original already on the original platform in advance. If there is no original on the original platform, this
operation is not performed.
*B: When there is an original in the original tray, the original set sensor (EMPS) output becomes LOW.
*C: Performance of this operation depends on whether there was any preliminary feed in steps 22 to 28.
Step 87:
Delivery motor (DEM) rpm decrease.
