    2.Detailed Descriptions Details Air Paper Feed Mechanism The air paper feed mechanism uses the air produced by the seven fans (float fan / separation fan / side fan (front/rear) / return fan / suction fan 1, 2) to handle and lift up and separate paper during the process of feeding paper.
  • Page 134 2.Detailed Descriptions transport roller [E] by the paper feed belt [D], and then fed to the vertical transport unit. Air blown from the separation fan and float fan is switched on/off by the shutter [F]. The air blown from the side air nozzles assist float and suction of the next sheet of paper. Also, it prevents double feed.
  • Page 135 2.Detailed Descriptions The three feed belts are installed at the same level. This improves the suction power and the feed quality for long paper. Fan Shutter Mechanism There is no shutters for the side fan, so air from the side fan (side air) always blows through while paper is transported.

  • Page 141 2.Detailed Descriptions Remaining Paper Detection The paper remaining is detected by counting pulses of the LCIT lift motor [A], and is shown in a four- stage display on the operation panel. When the bottom plate is lower than the paper height middle sensor [B], the remaining indicator is affected by the pulse count that starts when the plate passes the lower limit sensor [C].

  • Page 145 2.Detailed Descriptions Exit Roller Contact Mechanism This LCIT unit has a new roller contact mechanism (pair of four rollers contacts/separates) to release rollers that grip the trailing edge of paper when the SWIFT unit corrects the position of the paper in the main machine (Pro C9200/C9210 models only).
  • Page 146 2.Detailed Descriptions The contact operation of the rollers is the same way of the LCIT exit roller contact mechanism that is previously employed. As an example, the contact mechanism of the LCIT exit rollers is explained as follows. When the LCIT exit roller contact motor [A] is ON, it turns the cam [C] on the driveshaft via the belt [B]. The roller contact arm [D] moves up/down in conjunction with the cam, and this mechanism separates the slave exit roller [E] from the drive exit roller [F].
