    3BN/3A4 (1) Paper conveying operation in sort mode When a copy is made in the sort mode, the feedshift solenoid (FSSOL) turns on and the feedshift guide of the copier operates to switch the paper path to the feedshift section. The switchback solenoid (SBSOL) then turns on to lower the separation claw and the paper is conveyed to the intermediate tray by the feedshift roller.
