Paper Switchback Operation - Kyocera Mita KM-2530 Service Manual

(1) Paper switchback operation

Paper of which copying is complete is conveyed to the switchback unit and sent to the switchback section by the feedshift
guide. In the switchback section, paper is conveyed by touching of the switchback press roller rotated by normal rotation of
the switchback feed motor (SBFM), with the switchback press pulley activated by turning on the press solenoid (PRSOL).
When a certain time (depending on the paper size) elapses, the switchback feed motor (SBFM) reverses the direction of
rotation to reverse the rotation of the switchback press roller to switch the direction of paper conveyance.
Paper that has been switched back is conveyed to the saddle finisher by the switchback eject roller rotated by turning on the
switchback eject motor (SBEM) and the switchback eject pulley. At this time, the second paper is conveyed to the
switchback unit, the press solenoid (PRSOL) is turned off, the switchback press pulley separates from the switchback press
roller, and the first paper and the second paper are interchanged in the switchback section.
(Depending on the copier model and the paper size, the press solenoid may not turn off and the switch press pulley may
always touch the switchback press roller.)
