  • Page 36: Switching The Paper Path

    (1) Switching the paper path If the job separator is selected for the eject location, when a print is made, the feedshift solenoid (FSSOL) turns on and the feedshift guide of the machine operates to switch the paper path to the job separator. The printed paper is conveyed to the job separator and then ejected to the job separator tray.
