  • Page 38: Construction Of Each Section

    2-1 Mechanical construction 2-1-1 Construction of each section The paper conveying section consists of the components shown in Figure 2-1-1. It switches the path for the paper con- veyed from the machine in sort mode. Also the paper conveying section contains a curl eliminator mechanism, which reduces curling of paper with curl eliminator rollers.

  • Page 39: Paper Conveying Operation In Sort Mode

    (1) Paper conveying operation in sort mode In the sort mode, the feedshift solenoid (FSSOL) turns on and the feedshift guide of the machine operates to switch the paper path to the paper conveying unit. After curling of the conveyed paper is eliminated by the curl eliminator rollers, the paper is conveyed to the process table by the feedshift roller.
