  • Page 70: Driving Of The Timing Roller

    chap.2 c Paper Feed Section (3) Driving of the Timing Roller Timing roller is actuated to rotate by the pinion gear and spring clutch. When the paper feed cam rotates, the reciprocating motion of the timing roller segment is transmitted to the pinion gear, and the spring clutch works to rotate the Timing roller in the direction of conveyance.

  • Page 71: Escape The Guide Roller

    chap.2 c Paper Feed Section (4) Escape the Guide Roller After the Press roller is pressed to the drum, the printing paper is gripped firmly with the drum and Press roller, the Guide roller is released from the Timing roller. This is called "escaped". Escape timing is within a period when the printing paper is conveyed about 10 mm after it is gripped with the drum and Press roller.

  • Page 72: Paper Feed Length

    chap.2 c Paper Feed Section (5) Paper Feed Length The “paper feed length” is the length by which the paper feed roller feeds out the print paper. When the paper feed roller feeds out the print paper, the guide roller is pressed against the timing roller and does not rotate; as a result, the paper arches up between the paper separator and the timing roller, since the distance between these two items is only 80mm, while the length by which the paper is fed out from the paper feed roller is 95mm.
